Close to the same story. My dad finally gave me his 87 targa gte 5speed supra, that he got for his graduation vehicle. It is in need of restoration. I've been going through all your supra videos and learning all kinds of things. Thank you and keep them coming.
This is a good Supra to start with. No need to spend a big money on a replacement turbo especially if it on a Turbo 7M-GTE and it probably sound better too with Naturally Aspirated and not too fast for beginners either I see you out turbo on it. Well if someday I get wealthy then I can convert 7MGE to have turbo like 7M-GTE
Investing in a standalone that has short AND long term fuel trim was the best decision I made when re-wiring my 7M. With just a 2jz base map for the rough ignition table the ECU tuned the entire fuel table by itself and saved me big dollars on the dyno. Having a new loom is a big plus too as the old wiring is crusty as hell due to age and also limits you to stock perhipherals. This thing is looking to be a nice 7M! I do love the old M series, they seem to have a lot more character than the 1JZ that came in the later models. I have owned my 1988 Turbo A for over 6 years now and it was stock except for a turbo back exhaust. I have modified it over the years and its nearly done except I need to fit my cams and valvetrain upgrades. Starting from a bone stock chassis it has been great to feel the improvement after doing the coilovers, poly bushings/mounts, ECU, piping and brakes. I picked it up for AUD13.5k in 2016 which was top of the market given the rarity of the model and the fact it wasn't missing any parts. Nowadays mint examples are going for $60K its just crazy! I am glad I got one while I could afford it, prices were on the rise even back then. I look forward to seeing what you do with this mate
Thanks for reaching out man! Yeah I cannot believe how much some of these cars are going for. I was contemplating selling the car and I'm glad I decided to just hang onto it. Ive seen some 1989s going for upwards of 50-60k and in terrible condition. With my dad being the original owner it should have stayed in better condition but unfortunately with time and actually driving the car, things wear out and just get old. Oh the standalone has already been worth the money. I will do a whole video of when I send it out to get tuned (hopefully soon). I won't be even be close to utilizing all the features the ecumasters has to offer. I first purchased the DIY auto standalone and it was a waste of money and time. I was surprised at how easy it has been getting all the sensors and stuff wired in with this ecumaster. I'd love to see some pics of your car. follow me on my new instagram account supraluver and message me some pics. I just started to post pictures of mine and will also use that to document my build process. thanks again for reaching out man! best of luck on your build. Hit me up if you run into any issues.
Hey man, don't apologize for being a talking video. I actually really like your walk through of your mods VS 99% face cam. I have a 90 7mgte, so love seeing 7m content. I'd rather see the technical content VS the clickbaity shit. Subd
Thanks man! I appreciate it. I personally like the walk through stuff too. I will pump out some more videos and give more in depth info on my setup. I want to just keep it real and more personal. Thanks again for the comment and the sub man!
I don’t know how I got to this channel , but I’m glad I did, this is the type of build I want for mine , and I never thought of putting the turbo version taillight I guess I will do them now lol thank you for that , great video bro keep up the good work.
Thanks man! I really appreciate it! I'm glad you found my channel! I'm always looking for ideas for new content. I will do a video of the install for the turbo taillights. It's pretty easy but there are a few little tricks that make the install go smooth. Thanks again for the sub!
Awesome! Good decision! You won't regret it. I ran the hks mhg for a while and decided to switch over to the cometic gasket. Saved some money and the quality in my opinion was a little better.
@@nolan1812 yeah it's great quality. I'd suggest their full gasket set too. Pretty inexpensive and comes with all the replacement gaskets you need for a full rebuild.
I feel lucky coming across this video! I rarely see forward facing intake manifolds for the 7m motors. I have a 7mgte swap in my mx83 and i love this motor. I have a 2j in my garage waiting to be swapped in but I want to keep my 7m going because it's such it's not as popular and just different from what's normal today. Keep these 7m videos coming
Yes! Keep the 7m alive! No but seriously they are great motors. I've pushed mine pretty hard and it hasn't given me a bunch of problems. Yeah it's a built bottom end and of course a metal head gasket with ARP head studs, but honestly I'm happy with the motor and don't have any intentions on swapping it out. Keep up the work man and thanks for watching the vids!
@Jumpin through Hoopes funny thing is I spun a crank bearing back in 2016... it's been drifting and pushed hard even with a little knock. My friends tell me to swap the 2j but I keep telling them that the 7m just won't die and if that's the case it deserves to stay in the car
@ae86mia Haha that is awesome! Yeah I spun a bearing a while back and figured it was gonna blow and it never did so I decided to do a full rebuild and make it better and stronger. I've considered getting another 7m to do another build.
Recently purchased an 88mge-t car, apex-i piggyback using a 7mgte wiring harness. I got the head studs and head gasket done+ wide-band 02. Upgraded inter cooler, aluminum piping all the way around. I'm still in the process of decoding exactly what I bought and what I got myself into, but I'm excited for it.
Thanks for doing this video. Keep ‘em coming. Reading forum tips is one thing but actually seeing it is better. I have an ‘89 Turbo I’ve had since it was born. Planning on rebuilding for bigger HP so your content is helpful.
Radical man.. my 7mge has been sitting for several years but it's finally time to tinker. For real great video. I enjoyed staring at your engine bay & brainstorming. Thank you.
Love the car, love your work. Please keep the content coming. Not many people have channels about mk3 builds with 7M motors. I am teaching myself, I have a 7mge. Looking for all the help I can get haha 😂
@@deonghee5473 thanks man! I will definitely be posting more. I'm looking for around 500-600. I think I should be able to achieve that goal with what I've done with the motor.
That's the car I wanted in 88 so I really appreciate your video. Now I know what I'll have to pay to get one and what I'll want to do with it to make it nice
Mine is also a 7mge. I have been looking for a 2JZ but I recently picked up Another 7m but with targa roof. Been debating just fully doing what you did with your set up. Sweet build man!
I've got an 87 in my back yard. I told myself it needs to be done before my daughter's 16th birthday. She's 5 now so I need to get it going. I do plan on keeping the 7m ge because a 2jz swap would just be too obvious. I'll end up buying a 2jz for something else but this is pretty much the goal for mine
Hey! I bought a 7MGE '89 Supra a few years ago as a senior in high school. I didn't realize at the time what a complicated and unsupported car/engine I had bought, and its been giving me constant issues (300k miles, flood car, etc). I had never done an oil change on a car, yet decided to get it anyway because it was only $1,500. What you have is pretty close to my dream build. I want to keep the 7M, turbo it, etc. But so far, I've done nothing but strip out the interior and change the wheels. I just don't have a ton of time to work on it while in college Right now, it stalls on idle occasionally, the rear lamp failure box is faulty so my brake lights don't work, and the engine just feels very shaky, especially above 4-5k rpm. Do you have any recommendations for easy mods to make it run better, or to fix these problems? I'm excited to be a part of such a small community, I look forward to having a nice build at some point. Definitely subscribed, I want to see more of your Supra in the future.
Dude thanks for sharing your story man! Unfortunately as you have experienced, these cars are getting harder to find and Unfortunately most of them are in horrible condition and have been left outside to rot away. I'm glad to hear you are working on getting it back to the condition it should be in! As for the rough idling issue, I'd start with the simple stuff. Check the spark plugs, distributor, spark plu wires, boots...etc. check the spark plug galley and see if the valve covers have leaked oil into the spark plug holes. Check the distributor cap for cracks, look at the rotor and see if the contacts are worn out (easy to replace). When I had a misfiring issue similar to yours, my valves were burned up and causing similar rpm issues. Hopefully yours is something simple like I listed. Check those little things first and hit me up if its still having issues. I've been stoked hearing from all these other guys about their Supras and the progress they have made with them. It's a pretty awesome community and everyone is so willing to help out. I appreciate your feedback and I will continue to post videos. Thanks again man!
Nice car from glad to see someone else messing with the 7M. Your probably going to want to uncap that valve cover you have blocked off. Since you have A standalone you should definitely ditch that distributor and get a true trigger setup and coil on plugs.
That's the plan. That cap is just temporary. I will be making an AN line going from the valve cover back to the block. I will eventually do a trigger wheel and a coil over plug setup. Curious to see what the stock distributor limits are.
Your engine bay is looking amazing im definitely going to subscribe. I've been have really good results on my 86 mkiii running 7MGE electronics and fueling mods with my 2jzge build @8psi.
We just got an '87 Turbo model for my son in the same color, I do like the spoiler yours has in the rear compared to his. His GTR has the distributorless ignition. We're actually also in Utah.
Oh man he is super lucky! These cars are becoming more and more rare. The three piece spoiler looks really good on the car. My supra was a base model and didn't come with a spoiler at all, so it was a good addition. Yeah the distributor takes up a lot of space and limits my ability to tune. Hopefully I can do away with it soon. Don't hesitate to message me if you guys have any questions about the car.
What's up? I'm just in west valley. Pro machine has machined at least 7 4g63s for me, they do great work. Just got my wife a 89 mk3 like 95% original. She wanted to go 2jz but I think I'm just going to build the 7m. She wants about 500whp daily.
Dude thanks for reaching out! Yeah live promachine. I will continue to use them. They also did a 4g63 for me years ago. As for the supra I'm all about the 7m but that's just me. If you have promachine deck the head and block to run a metal headgasket with ARP studs will hold together no problem. I'd maybe look into some forged internals for some added reliability. I did wiseco 84mm pistons strapped to some eagle H beam rods.
@mainstreambuilds I've built over 50 engines. I actually build turbos for a living. Just sold my 535whp 92 galant vr4. Bought a 05 is300 I'm going to build to a gte spec. Are you running emu from ecu masters?
@richardwilliams9815 oh that's rad! I had a 2dr mitsubishi mirage with a 4g63. It was a blast. Yeah I'm running the emu classic. It's sort of on a stand still until the weather warms up a little more and I find the motivation haha. It's super close right now I'm just slightly off on timing and need to check it again. Other than that everything seems to be working pretty well.
I live in Utah too. In the Layton area. I have had 240sx, FC RX7, and wanted to get into the 85-88 280sx. I definitely want to stay in the 80’s though. I wanted something different then what everyone else is doing. Then I remember seeing an old abandoned turbocharged 88 celica supra and haven’t seen anyone really get into one. So I started to do some research and landed on your video. Your car is damn good looking and just inspired me even more to go ahead and pull the trigger on one. So thank you for that. Also, did you know you used the spacers, UH and UHM, or some variant of them 157 times in this vid😂😂😂. Well now you do. Keep up the good work.
Haha thanks for the feedback man! Keep goin on those projects! We need more of these cars on the road. Haha yeah I noticed the ummm and uhhh as well. Haven't done a video in a while so I was uhhhh ummming a lot. Hopefully my videos get better as I make more.
That's awesome! I've toyed with the idea of swapping motors but the 7m is a decent motor and can hold some good power with a little work. My machine shop told me that the factory 7m (turbo) rods are plenty strong for decent power. My plans were 500ish and the shop was certain the rods could hold it. Pistons on the other hand not so much.
Nice ride ...I definitely know what you mean when you say everything has been modified. I've owned a few Supra's over the years. My Mk3 Supra also has plenty of mods including full interior upgrades and exterior paint. Always garaged and barely drive it now due too value and idiot drivers 🤬. 18x9 fronts 19x10 rears Swapped 2jzgte engine that's been built with just about every new part available. GR T-56 installed 1300 whp is my goal. 😂👌🏁🏁🏁
Beautiful build, maybe I missed it but the hose that goes from the valve cover to the block what did you do for that? On intake side see you blocked it off by the oil cap.
I actually learned it's not ideal to just block that off. I did another video where I use a -10AN push lock fitting and run the hose down to the block.
@@mainstreambuilds thanks for the update, I ended up going 1JZ vvti and truly regret selling my 7MGTE instead of building it but have buddy’s out here in Texas that still run the 7M.. I’ll check out that other video!
@JSXECO I thought about going that route as well. I'm glad I built my 7M. Great learning experience and have had a ton of fun in the process. I actually just dropped the car off to the tuner tonight so I will be doing an update video very soon!
I keep tossing the idea around with going 1 or 2j, but then I think why? It's a great power plant. Honestly, any engine will need a little work to produce some good power. It's a simple motor, strong, and sounds good!
I’m not sure if I missed but you mentioned oil squirters on the 7mgte, did you add oil squirters to your ge?? & how much did this build run you? Just got my hands on an 86 Supra and trying to map things out
Since I ended up going with forged internals, it wasn't necessary to add oil squirters. I was actually talking to a guy the other day about overall costs. I saved a bunch of money by doing all the fab stuff myself, but I'd say overall, I'm probably 8-10k.
Thanks for checking out the vid. I've been through several different types. I'm currently running royal purple but will be switching to valvoline on my next change.
Sorry man didn't see your message. I snagged mine off ebay. I made sure it was decent quality. The xs powersports plenum will accommodate a 4 bolt 90mm throttle body. I think mine is the OBX billet 90mm body that works with the older toyota throttle position sensor.
hey my dude, cool vid and thanks for pouring content on your build. i found me a blue 86 hardtop and purchased it yesterday! do you have a guide from going to ge to gte and if not, may you create a spreadsheet and video for noobs like me? mines a ge and overheard the engine was bored out (is doing a compression test a way to determine how much the engine was bore?). overall, i'm looking to get a nice fun street car like how you were mentioning. also, glad to say i'm officially in the supra gang:)
Sorry it's been so long my man! Hopefully all is well and your able to cruise around. I'd be more than happy to make a list for you. I'm sure with how much time has passed you might have already done some research on your own. Let me know if you still need this info and I can do a short video. These motors are actually pretty fun to tinker with and might seem a little complex but they are very simple. Congrats on the purchase! You will not be disappointed.
Looks amazing. I own a 1990 NA 5speed, This is exactly how I want my 7MGe to look but I’m good with out the turbo I just want a cleaner look like what you did with the intake. Also good idea for the valve covers by making look flat on top , I’m not a big fan of how they look with the dip in the middle . Love the car . Can’t wait to see it through the changes of the ecu and also see the power numbers . Keep the Vids coming . All Mk3 and supra owners need this type of content to keep us motivated to work on our own cars. Best of luck with the channel . I’m here to stay
Thanks man! I really appreciate the feedback. I agree with you as far as the lack of mk3 supra content on RUclips. I hope my videos are informative and help.
@@mainstreambuilds yea man you’re the only one I know of that explains everything thoroughly . I literally was looking for some content today to get motivated to work on the Mk3 and I came across your Channel. Glad I did hehe , good look with everything man.
Hey just coming across your channel and just wondering if you’ve had the same problem as me, so this is my 2nd mk3 but this one is new which is a 87 with a 91 swap and a warlboro 255, but for some reason whenever you start the car and the engine is warm it tends to need a rev typically up to 2k or it’ll stall, or if I’m just chillin in neutral and rev it under 2k it’ll start to stall out and I have to rev it back to life, if anyone else has had this issue lmk
I've heard of other people having this issue as well. I haven't experienced this personally, but I wonder if is making the car run rich so the 02 sensor is telling the ecu to kill power. Do you have the factory fuel pressure regulator and fuel damper?
@@mainstreambuilds I noticed that the cam angle sensor had these cheap crimp on connectors so I replaced those and soldered the wires and it seemed to remedy the random dying out a little but it’ll occasionally come back but it completely fixed the occasional misfire i was having
Thanks man! And thanks for checking out my channel. The intake manifold is an XS powersports plenum welded to the 7m runners. The plenum kit is for a 2jzge. It worked out perfect, looks and sounds amazing.
@Nick McDermott haha everyone asks about the intake manifold so I just assumed. We tig welded the manifold using weld els from treadstoneperformance.com it's a T3 manifold so I'm sure I'm a little limited on power, but it gets the job done. Its fitted with a 38mm wastegate, but that will be upgraded eventually.
I have a '87 Toyota Supra one owner car. I have had it parked for a good while, and now trying to get it started again. Do you know it the 87 has a crankshaft sensor, and where it is located?
@ManuelLopez-ti9od that's awesome! Get er runnin! The 7mge doesn't have a crank sensor. The only "sensor" You have is the distributor. It will run off the cam and deliver spark through the rotar inside the distributor. My guess if it's not running the fuel is probably bad or clogged injectors. I'd run through and just check spark on each spark plug as you crank it over. I'm willing to bet it's something with fuel. Injectors, fuel pump, fuel filter....etc
@@mainstreambuilds I have another question if you would be so kind to answer. Do you know where the fuel inlet line is to the fuel rail on the '87 Supra? I have a line (fuel-?) at the end of the fuel rail near front of car that is connected to some device screwed into the fuel rail; I have a line (fuel-?) 2/3rds back towards the firewall; and I have a line (fuel-?) that is at the end of the fuel rail closest to firewall screwed into another similar to front device. Not sure which of these is the fuel inlet line. I am using a fuel injector cleaning kit to bypass the gas tank.
@ManuelLopez-ti9od not a problem at all! So the one at the front of the rail is going to be your return to the tank and the thing screwed into the rail with the banjo fitting is a small fuel pressure regulator. The fitting in the middle of the two towards the back of the rail us the feed for the cold start injector. The fitting at the very back of the rail will be the inlet from the tank to the fuel rail. You could pop the back fitting off and place in a bucket or some sort of a catch and then turn the motor over and see if any fuel comes out of that fitting. Again be careful as you will be dealing with pressurized fuel. Also the little weird fitting thing on the back of the rail where the fuel comes in is a fuel damper to help prevent a little fuel surge.
@@mainstreambuilds Thank you for your feedback. I appreciate it. I will try to use my fuel injectors cleaning device to connect to the back inlet fuel line to pressurize and bypass filthy gas tank.
i have a 7m-ge toyota cressida with arp headstuds and brand new head gasket but i keep hearing theyre too expensive to be worth it over a jz and im considering a swap.
I definitely contemplated doing the swap myself but I wanted to try and keep it "original". I definitely want to turn mine up more. Keep me posted on what you do!
@lucioucz oh I super content with my 7M. It holds great power and I haven't had to throw a ton of money at it. I got the block and head machined a few years ago and haven't had any issues. The forged internals didn't cost an arm and a leg either. In my opinion it's a great motor to learn on.
Do you still have the MK3 ? I just recently bought one and I am taking out the engine to get it rebuilt, do you have any recommendations that I can use to start ?
@erosa5025 sure do! Actually just got back from a short drive. If you are in the salt lake area, I used a company called pro machine in murray. They have been around for a looong time. They build a lot of supra motors for the local guys. Highly recommend!
Considering this video is 9 months ago, did you ever install your ecu into the stock wiring harness? Which ecu did you use and what were some changes you made to the stock harness? Personally Im gonna have to find an aem or pro efi ecu since tuners around here use that, but I need an idea of what changes Im looking at before I do my own na-t project. I love the build by the way the FFIM really modernizes the engine bays of these cars.
Yeah I've been slacking on the uploads and haven't given a recent update on this. I decided to bag the megasquirt and went with the ecumaster EMU classic. I finished wiring all the inputs and ran into an issue with the ignition signal. I got the adapter harness from ecumaster and I guess the wiring isn't correct so I've been needing to figure that out. So far it's been super easy to work with and I would recommend it. Another guy I know is running 500hp on his 7m with the ecumaster. I will try to do an update video on this soon.
Hey I was curious if you had any issues running the pnp adapter for the ecumasters standalone. I know the GE and GTE harnesses have a slightly different pinout, and they don't have a GE adapter. It's really the only thing that's kept me from buying it. I have GTE harnesses but they're hacked and my GE is mint so I'd prefer not to change it if I don't have to.
So I havent had to repin anything on my actual harness. All the cutting and splicing is done on the pnp adapter and ecumasters has done a great job with showing you how to add sensors and how to test everything on the ecumasters tuning software. If you do need to move the jumper wires, ecumasters provides great documentation on how to do it. I made sure to get the pnp for the ge (yellow connector not the grey) I haven't gotten it tuned yet but so far everything seems to be working properly through the tuning software. I've added intake air sensor, Mac valve for boost control, marlin crawler transmission speed sensor (for launch control), wired in a wide band 02 sensor, and a fuel pressure sensor. I should be getting it tuned very soon and I can give you guys some feedback.
I will do a video on my ecumasters setup. Hopefully that will give everyone a better idea. I'd definitely recommend it. Great unit for a decent price. I'm no genius when it comes to electronics and I was able to figure this out. Ecumasters has uploaded a ton of very well done videos on RUclips which give step by step instructions.
@@mainstreambuilds Ok thanks for the info. It definitely seems like the best route short of building a custom harness for any other standalone. I’m also tempted to keep my distributor and coil like you have, just curious what the power limits will be before the coil will need to be upgraded. Make sure to post videos whenever you get it tuned too!
@@_Bonez12 yeah you shouldn't need to cut anything besides the pnp. I was in the same boat as you. I even bought a separate used harness just in case but didn't end up using it. The guy tuning my car said the distributor will definitely limit the HP but it should get me around the 500hp mark I'm looking for. I will definitely keep you posted. Worse comes to worse I will drop some coin and get a trigger wheel and do a coil over plug setup.
I bought my mk3 about a year ago, it runs pretty good and it has about 200k miles, the last owner did a few cosmetic modifications but the engine is a stock 7mge and I’ve been thinking about turboing the engine. Where would you recommend I start?
It really comes down to how much you are willing to spend. A built 7mgte would obviously be better than a stock 7mge. If you are going to turbo the GE I would start out with building a decent foundation. Headgasket will most likely be your main issue. The factory headgaskets and head bolts aren't sufficient enough for boost. I'd look at maybe getting block and head resurfaced and run a metal headgasket with arp studs. Unfortunately I learned the hard way and kept fixing little bits here and there when I should have just pulled the motor out and installed a metal headgasket, studs, forged rods and pistons, and a shimmed oil pump.
It can definitely be done, it just needs a little work 320 isn't insane, but it is roughly 100hp more than factory. Doesn't seem like a lot but it can take some work to get there. I hope you do it! I love hearing people experimenting with the 7M and making it what it should be! Keep me posted.
I recently bought an '88 7M-GE and would like to turbo it in the future. Right now its not in running condition due to a broken timing belt issue. Do you have any advice for getting it working again?
I will be doing another video soon on how to turbo the 7m. Hopefully I can crank that out soon. As for the timing belt issue, if there is no internal damage from the belt breaking and pistons hitting valves. If all is good you could reset timing and throw in another timing belt. I would pull the spark plugs and crank the engine over by hand and see if it seizes or locks up during the rotation. The last thing you want is a catastrophic failure.
@@mainstreambuilds Thanks! I'm new to the car sphere but want to get into it as a project car. I do have some mechanical know how and have friends who are professional mechanics. Is there and online group or something for the mk3 supra I could join to learn more about this car?
@CaptainAwsome73 oh very nice. These cars are relatively simple to work on. You could always scroll through supra forums and get some good info there. Some of the info can be pretty old but still worth scrolling through.
It actually works pretty well. Low boost and 550cc injectors, it seems pretty happy. I will eventually run a trigger wheel setup with coil over plugs just so it's more efficient, but I've been running it on stock electronics for a while and haven't had any issues.
I've always loved this car. I'm 33 years old now and I remember my dad dropping me off at school in "the supra". I will try and keep this car in my family as long as possible. I still joke with my wife about how much attention this car gets. She experienced it first hand when I was stopped at the gas station and the kid wanted pictures and videos and kept saying "I can't believe I'm seeing this". His reaction made it all worth it. Hopefully you can keep your supra in your family for a very long time.
My dad is also giving me his supra and its completely stock besides repaired parts, and I want to ask if you think it's worth it to put a turbo on the original 7M-GE?. I plan to rebuild the engine anyways but finding parts is hard and I'm not sure if I should take the risk and put a turbo.
@amazinjason4959 that's awesome! So that's what I did, put a turbo on my GE. The only thing you need to be mindful of is that stock head gasket and head bolts. They won't hold boost and will pop pretty easily. I'd have the the block and head decked by a machine shop and throw in a metal headgasket with some ARP head studs.
@amazinjason4959 It can definitely be done and I highly recommend it. Turbos are everything haha! If you have questions along the way feel free to ask.
@amazinjason4959 Nope, only if you decide to run a bigger fuel pump, injectors, wideband......etc. I ran my car on factory wiring and ecu. I wired in 550cc injectors, bigger fuel pump, and wideband to watch AFRs. Obviously it's ideal to run a standalone so it can be tuned and run efficiently.
my dad is finally giving me his stock 7mgte mk3. it was a junkyard supra from what he told me and brought it back to some life. still not in its best state and has lots of issues. when braking it stutters and doesnt brake all the way, just kinda goes in and out until it fully stops. another issue is when turning the steering wheel clockwise it starts to make a rattling noise in the front left wheel. I have lots of plans for it but i atleast want to make it drivable as of now. Im pretty clueless when it comes to working on a car but im determined to fix this beauty. what should i start with ?
Thanks for sharing man! That's awesome! So to me it sounds like some new brake rotors might be needed. I'd also check the brake master cylinder and even the slave cylinder. It may have a small leak in the brake system from it sitting. I'd bleed the system and see if that fixes your issues. As for the rattling that could be a wheel bearing which isn't too difficult to replace. I personally would get that stuff sorted out before throwing performance stuff at it. If you have the money and time I'd start with a metal head gasket and ARP head studs. The engine will require some machining so the gasket completely seals. The head and block will need to be resurfaced in order for this to work. This process will be a good base to start with. The 7MGTE/GE are notorious for blowing headgaskets and can cause some major damage when they fail. You could also do some simple things such as replacing the mass air flow sensor with the Lexus mass air flow sensor, do the is300 coil pack conversion, and going with slightly larger fuel injectors. The CT26 turbo is great but very limited when it comes to increasing boost. You could get the CT26 that has been modified to flow a little more air. You could also do an exhaust with a larger downpipe and even a slightly larger intercooler. These cars have a lot of potential the hardest part is figuring out where to start. Hope this helps steer you in the right direction.
@@mainstreambuilds thanks for all this information. Im 21 and it looks like ill be dumping a fair amount of money until im satisfied. Please dont disappear because you are one of the few 7mgte youtubers that i look forward to watching and learning
in other words, you got any parts that you think I could turbo this on the cheap end? I cant really weld an intake manifold but i can drill into the oil pan and such
I'm actually planning on doing a video on this soon when I go to swap out turbos. It's not super involved. I had the bottom end built to support the boost and not huck a rod, cometic metal headgasket, arp head studs, wiseco pistons, eagle rods, and arp main and rod bolts.
@Crispified98 I wanted a good base to build on. The 7M can definitely hold the power with a little work. In my opinion it's worth building. Like 1j and 2js the 7ms are now going up in proce quite a bit and worth hanging on to.
So both my seats are stiff back (don't recline). I used the corbeau solid brackets. Once I did my roll cage I couldn't slide my seats back and forth. Corbeau sells the brackets specifically for our cars. I can do a short video talking about them if you are interested.
@@mainstreambuilds I was hoping you had a different bracket because I bought a set of Corbeau RRX’s not too long ago with the Corbeau sliders and brackets but it made me sit too high. Even without the sliders I didn’t sit right. I was going to buy another set of seat brackets from a different manufacturer but after looking at it, there can’t be much of a difference with another brand either. I’m guessing the seats possibly play a role in seating position as well. It would be nice to see how yours is mounted though. 👍
@@shuexiong2620 I have the fx1s and I had the same issue. They would sit way too high. The non-sliding brackets are a lot lower but they are fixed and won't move. The brackets definitely have enough material to drill the holes forward or back to adjust the seat if needed. I will do a video on it for ya. I've had other people asking about them too.
Lucky! Don't let go of it! As for advice I'd figure out what you want to do with the car. Do you want it for a few around town car, drift car, drag car? That will help with pointing you in the right direction for what power plant would be best. The possibilities are endless, however parts are getting harder to find and expensive. Try to find what you need and get building! These cars are so much fun and pretty easy to work on.
@@Confestus its going great! Making 352whp and 496nm torque, running healthy on a pretty basic setup. Hasn't given me much trouble to be honest, if you have any troble with your build contact me! Glad to hear you are starting a great project like this car is!
Naaa. If anything it might be a little on the small side. I have another dual ball bearing turbo with a larger turbine housing I may throw on eventually. The holset I have now is pretty limited and will max out fairly quickly.
Everyone kinda has their own opinions when it comes to this topic. A lot of people will say the 1jz is far more reliable. I've driven my supra from Utah to Nevada several times and the only issue I had was my AC compressor went out. Other than that the car ran flawlessly. I've also seen a 1jz supra over heat and stop running. It had to be towed to the next town. In my opinion both motors are great. I'd for sure have the 7m block decked and head resurfaced and throw in a metal headgasket with ARP studs. I had this done many years ago and drove the supra as a daily for a while with no issues. Whenever I get asked this question I usually respond with "what is your goal for the car?". Depending on what you want to do with the car you may need some deep pockets. I put quite a bit of money in my car but I enjoy it and drive the s*** out of it.
@@mainstreambuilds ah I see, thanks for sharing your experience :D to be honest i love A70 and im having a plan to bought one, the only problems that i had right now was umm you know the engine itself 7M that giving me a doubts, and many people owning A70 mostly swap the 7M with 1 or 2JZ engine, could you gave me some advice? maybe a guide about purchasing A70? :D
Yes! Very true. Slap a turbo on it and have fun! People get too caught up in all the turbo vs non-turbo stuff. If it makes turbo noises and brings happiness then goal accomplished!
Close to the same story. My dad finally gave me his 87 targa gte 5speed supra, that he got for his graduation vehicle. It is in need of restoration. I've been going through all your supra videos and learning all kinds of things. Thank you and keep them coming.
0:22 Woah bro why you staring at me like that 🥶
This is a good Supra to start with. No need to spend a big money on a replacement turbo especially if it on a Turbo 7M-GTE and it probably sound better too with Naturally Aspirated and not too fast for beginners either
I see you out turbo on it. Well if someday I get wealthy then I can convert 7MGE to have turbo like 7M-GTE
Investing in a standalone that has short AND long term fuel trim was the best decision I made when re-wiring my 7M. With just a 2jz base map for the rough ignition table the ECU tuned the entire fuel table by itself and saved me big dollars on the dyno. Having a new loom is a big plus too as the old wiring is crusty as hell due to age and also limits you to stock perhipherals.
This thing is looking to be a nice 7M! I do love the old M series, they seem to have a lot more character than the 1JZ that came in the later models. I have owned my 1988 Turbo A for over 6 years now and it was stock except for a turbo back exhaust. I have modified it over the years and its nearly done except I need to fit my cams and valvetrain upgrades. Starting from a bone stock chassis it has been great to feel the improvement after doing the coilovers, poly bushings/mounts, ECU, piping and brakes.
I picked it up for AUD13.5k in 2016 which was top of the market given the rarity of the model and the fact it wasn't missing any parts. Nowadays mint examples are going for $60K its just crazy! I am glad I got one while I could afford it, prices were on the rise even back then. I look forward to seeing what you do with this mate
Thanks for reaching out man! Yeah I cannot believe how much some of these cars are going for. I was contemplating selling the car and I'm glad I decided to just hang onto it. Ive seen some 1989s going for upwards of 50-60k and in terrible condition. With my dad being the original owner it should have stayed in better condition but unfortunately with time and actually driving the car, things wear out and just get old.
Oh the standalone has already been worth the money. I will do a whole video of when I send it out to get tuned (hopefully soon). I won't be even be close to utilizing all the features the ecumasters has to offer. I first purchased the DIY auto standalone and it was a waste of money and time. I was surprised at how easy it has been getting all the sensors and stuff wired in with this ecumaster.
I'd love to see some pics of your car. follow me on my new instagram account supraluver and message me some pics. I just started to post pictures of mine and will also use that to document my build process.
thanks again for reaching out man! best of luck on your build. Hit me up if you run into any issues.
Hey man, don't apologize for being a talking video. I actually really like your walk through of your mods VS 99% face cam. I have a 90 7mgte, so love seeing 7m content. I'd rather see the technical content VS the clickbaity shit. Subd
Thanks man! I appreciate it. I personally like the walk through stuff too. I will pump out some more videos and give more in depth info on my setup. I want to just keep it real and more personal. Thanks again for the comment and the sub man!
I don’t know how I got to this channel , but I’m glad I did, this is the type of build I want for mine , and I never thought of putting the turbo version taillight I guess I will do them now lol thank you for that , great video bro keep up the good work.
Thanks man! I really appreciate it! I'm glad you found my channel! I'm always looking for ideas for new content. I will do a video of the install for the turbo taillights. It's pretty easy but there are a few little tricks that make the install go smooth. Thanks again for the sub!
Same happy to find it and follow all mk3 builds save the 7m!!
this is rad keep the 7m content coming! just pulled mine to do mhg and refresh
Awesome! Good decision! You won't regret it. I ran the hks mhg for a while and decided to switch over to the cometic gasket. Saved some money and the quality in my opinion was a little better.
@@mainstreambuilds sweet i'm glad i decided to go with the cometic gasket too!
@@nolan1812 yeah it's great quality. I'd suggest their full gasket set too. Pretty inexpensive and comes with all the replacement gaskets you need for a full rebuild.
I’m on the same mission
I feel lucky coming across this video! I rarely see forward facing intake manifolds for the 7m motors. I have a 7mgte swap in my mx83 and i love this motor. I have a 2j in my garage waiting to be swapped in but I want to keep my 7m going because it's such it's not as popular and just different from what's normal today. Keep these 7m videos coming
Yes! Keep the 7m alive! No but seriously they are great motors. I've pushed mine pretty hard and it hasn't given me a bunch of problems. Yeah it's a built bottom end and of course a metal head gasket with ARP head studs, but honestly I'm happy with the motor and don't have any intentions on swapping it out. Keep up the work man and thanks for watching the vids!
@Jumpin through Hoopes funny thing is I spun a crank bearing back in 2016... it's been drifting and pushed hard even with a little knock. My friends tell me to swap the 2j but I keep telling them that the 7m just won't die and if that's the case it deserves to stay in the car
@ae86mia Haha that is awesome! Yeah I spun a bearing a while back and figured it was gonna blow and it never did so I decided to do a full rebuild and make it better and stronger. I've considered getting another 7m to do another build.
Subscribed! Good to find MK3 content for inspiration - Have a '91 JZA70 so very relevant. Coming up 12 years that i started upgrades, ha!
Thanks man! Keep it up man! We need more of these cars on the streets. It's such a fun car to own and it's always turning heads!
Recently purchased an 88mge-t car, apex-i piggyback using a 7mgte wiring harness. I got the head studs and head gasket done+ wide-band 02. Upgraded inter cooler, aluminum piping all the way around. I'm still in the process of decoding exactly what I bought and what I got myself into, but I'm excited for it.
Keep me posted! It can always be a mystery with these cars ha.
Thanks for doing this video. Keep ‘em coming. Reading forum tips is one thing but actually seeing it is better. I have an ‘89 Turbo I’ve had since it was born. Planning on rebuilding for bigger HP so your content is helpful.
Thanks I appreciate it! I will keep them coming for sure!
Sick build man! Thanks for sharing. I’ll be diving into my 7M-GTE build hear soon. Saving this for inspiration 100p!
Thanks for checking out the channel man! Get that thing out on the road asap!
Radical man.. my 7mge has been sitting for several years but it's finally time to tinker. For real great video. I enjoyed staring at your engine bay & brainstorming. Thank you.
Thanks man! I really appreciate it!
Same . This got me so motivated to work on mine .
Love the car, love your work. Please keep the content coming. Not many people have channels about mk3 builds with 7M motors. I am teaching myself, I have a 7mge. Looking for all the help I can get haha 😂
Thank you! I definitely will! Hopefully I can get some more videos out really soon! Hit me up if you ever have any questions.
Nice video man, good quality keep em up :) not alotta new 7m content on RUclips
and what are your HP goals?
@@deonghee5473 thanks man! I will definitely be posting more. I'm looking for around 500-600. I think I should be able to achieve that goal with what I've done with the motor.
Great video mate, when you get a min have a look at my mk3 7mgte, we're nearly ready to race. Thanks.
Will do man! Thanks for checking out the channel.
That's the car I wanted in 88 so I really appreciate your video. Now I know what I'll have to pay to get one and what I'll want to do with it to make it nice
Thanks for checking out the video! If you get your hands on one, don't let it go!
Mine is also a 7mge. I have been looking for a 2JZ but I recently picked up Another 7m but with targa roof. Been debating just fully doing what you did with your set up. Sweet build man!
Oh nice! You should totally do it! I've been really happy with my setup!
I've got an 87 in my back yard. I told myself it needs to be done before my daughter's 16th birthday. She's 5 now so I need to get it going. I do plan on keeping the 7m ge because a 2jz swap would just be too obvious. I'll end up buying a 2jz for something else but this is pretty much the goal for mine
Nice dude! Look forward to seeing the progression. Let me know if you have any questions!
got me a mk 3 91 , think ill be following this channel for further info ,mine is very similar to yours, even got the same color bro
Sweet! Glad you stumbled across my channel! Keep me posted on your build and if you have any questions feel free to message me!
Keep enjoying your hard work ☺️ you make me want to get mine ready for spring 🌱
Thank you! We need more supras out there!
7m yesssss much love building mine no crazy power just want it bullet proof drop more info and updates
Will do man! Actually editing a video as we speak.
Finally someone with a good video on the Mk3👌 thanks and keep it coming please
Absolutely! Thanks for watching and supporting the channel. More videos to come!
Hey! I bought a 7MGE '89 Supra a few years ago as a senior in high school. I didn't realize at the time what a complicated and unsupported car/engine I had bought, and its been giving me constant issues (300k miles, flood car, etc). I had never done an oil change on a car, yet decided to get it anyway because it was only $1,500. What you have is pretty close to my dream build. I want to keep the 7M, turbo it, etc. But so far, I've done nothing but strip out the interior and change the wheels. I just don't have a ton of time to work on it while in college
Right now, it stalls on idle occasionally, the rear lamp failure box is faulty so my brake lights don't work, and the engine just feels very shaky, especially above 4-5k rpm. Do you have any recommendations for easy mods to make it run better, or to fix these problems?
I'm excited to be a part of such a small community, I look forward to having a nice build at some point. Definitely subscribed, I want to see more of your Supra in the future.
Dude thanks for sharing your story man! Unfortunately as you have experienced, these cars are getting harder to find and Unfortunately most of them are in horrible condition and have been left outside to rot away. I'm glad to hear you are working on getting it back to the condition it should be in!
As for the rough idling issue, I'd start with the simple stuff. Check the spark plugs, distributor, spark plu wires, boots...etc. check the spark plug galley and see if the valve covers have leaked oil into the spark plug holes. Check the distributor cap for cracks, look at the rotor and see if the contacts are worn out (easy to replace). When I had a misfiring issue similar to yours, my valves were burned up and causing similar rpm issues. Hopefully yours is something simple like I listed. Check those little things first and hit me up if its still having issues.
I've been stoked hearing from all these other guys about their Supras and the progress they have made with them. It's a pretty awesome community and everyone is so willing to help out. I appreciate your feedback and I will continue to post videos. Thanks again man!
hey man how's the car been?
Nice car from glad to see someone else messing with the 7M. Your probably going to want to uncap that valve cover you have blocked off. Since you have A standalone you should definitely ditch that distributor and get a true trigger setup and coil on plugs.
That's the plan. That cap is just temporary. I will be making an AN line going from the valve cover back to the block. I will eventually do a trigger wheel and a coil over plug setup. Curious to see what the stock distributor limits are.
@@mainstreambuilds sounds good lmk if you have any trigger questions.
@@TheMotoxxx87 what trigger wheel and coils would you recommend for the ecumasters
Your engine bay is looking amazing im definitely going to subscribe.
I've been have really good results on my 86 mkiii running 7MGE electronics and fueling mods with my 2jzge build @8psi.
Thanks man! Yeah it works surprisingly well. Thanks for the sub! I have some plans for some good upcoming videos.
Nice car man... Love the MK3 Toyota Supra
Thanks man!
We just got an '87 Turbo model for my son in the same color, I do like the spoiler yours has in the rear compared to his. His GTR has the distributorless ignition. We're actually also in Utah.
Oh man he is super lucky! These cars are becoming more and more rare. The three piece spoiler looks really good on the car. My supra was a base model and didn't come with a spoiler at all, so it was a good addition. Yeah the distributor takes up a lot of space and limits my ability to tune. Hopefully I can do away with it soon. Don't hesitate to message me if you guys have any questions about the car.
@@mainstreambuilds thank you, I appreciate it and I'm sure my son will also!
nice man, just a fun fact... some of the JDM GTE's didn't come with oil squirters either, but all euro GTE's did
What's up? I'm just in west valley. Pro machine has machined at least 7 4g63s for me, they do great work. Just got my wife a 89 mk3 like 95% original. She wanted to go 2jz but I think I'm just going to build the 7m. She wants about 500whp daily.
Dude thanks for reaching out! Yeah live promachine. I will continue to use them. They also did a 4g63 for me years ago. As for the supra I'm all about the 7m but that's just me. If you have promachine deck the head and block to run a metal headgasket with ARP studs will hold together no problem. I'd maybe look into some forged internals for some added reliability. I did wiseco 84mm pistons strapped to some eagle H beam rods.
@mainstreambuilds I've built over 50 engines. I actually build turbos for a living. Just sold my 535whp 92 galant vr4. Bought a 05 is300 I'm going to build to a gte spec. Are you running emu from ecu masters?
@richardwilliams9815 oh that's rad! I had a 2dr mitsubishi mirage with a 4g63. It was a blast. Yeah I'm running the emu classic. It's sort of on a stand still until the weather warms up a little more and I find the motivation haha. It's super close right now I'm just slightly off on timing and need to check it again. Other than that everything seems to be working pretty well.
@@mainstreambuilds that's awesome. We are selling her evo 9 to fund all of this. Probably tear the engine out next month and start going on it.
@@richardwilliams9815 oh sweet! Keep me posted. Feel free to hit me up anytime if you have questions.
You doing good bro we appreciate all you do!
Thanks man! I appreciate it
Love the car keep it up
Thanks! More to come!
Interesting setup.
I live in Utah too. In the Layton area. I have had 240sx, FC RX7, and wanted to get into the 85-88 280sx. I definitely want to stay in the 80’s though. I wanted something different then what everyone else is doing. Then I remember seeing an old abandoned turbocharged 88 celica supra and haven’t seen anyone really get into one. So I started to do some research and landed on your video. Your car is damn good looking and just inspired me even more to go ahead and pull the trigger on one. So thank you for that. Also, did you know you used the spacers, UH and UHM, or some variant of them 157 times in this vid😂😂😂. Well now you do. Keep up the good work.
Haha thanks for the feedback man! Keep goin on those projects! We need more of these cars on the road. Haha yeah I noticed the ummm and uhhh as well. Haven't done a video in a while so I was uhhhh ummming a lot. Hopefully my videos get better as I make more.
Awesome… keep on doing more videos
I’ve got a healthy 7m in my cressy, also have spare 1jz and 2jz….. but really keen on keeping the 7m and boosting it. Rods will handle 500hp yeah.?
That's awesome! I've toyed with the idea of swapping motors but the 7m is a decent motor and can hold some good power with a little work. My machine shop told me that the factory 7m (turbo) rods are plenty strong for decent power. My plans were 500ish and the shop was certain the rods could hold it. Pistons on the other hand not so much.
Nice ride ...I definitely know what you mean when you say everything has been modified. I've owned a few Supra's over the years. My Mk3 Supra also has plenty of mods including full interior upgrades and exterior paint. Always garaged and barely drive it now due too value and idiot drivers 🤬. 18x9 fronts 19x10 rears Swapped 2jzgte engine that's been built with just about every new part available. GR T-56 installed 1300 whp is my goal. 😂👌🏁🏁🏁
I have 1 86.5 and 1 87mgte with vintage old school vintage hks on the 87 .. turbo spun rod bearings.......manual w58 and R154 on 87 ...._Philly
Man i want one of these cars so bad! So hard to find her in NY!
Unfortunately they are getting harder to find everywhere.
I've got a 1985 Celica Supra GTS that I'm trying to put a 7m-GTE Motor in replacement of the 22RE and I'd love to talk to you about the swap
Awesome! I'm all ears man! Hit me up on instagram messenger @supraluver
thumbs up for a fellow 7M!
Thanks man!
Beautiful build, maybe I missed it but the hose that goes from the valve cover to the block what did you do for that? On intake side see you blocked it off by the oil cap.
I actually learned it's not ideal to just block that off. I did another video where I use a -10AN push lock fitting and run the hose down to the block.
@@mainstreambuilds thanks for the update, I ended up going 1JZ vvti and truly regret selling my 7MGTE instead of building it but have buddy’s out here in Texas that still run the 7M.. I’ll check out that other video!
@JSXECO I thought about going that route as well. I'm glad I built my 7M. Great learning experience and have had a ton of fun in the process. I actually just dropped the car off to the tuner tonight so I will be doing an update video very soon!
why is the oil drain line from the valve cover blocked off? getting the oil back down to the pan is pretty important
just got a 1987 supra 7mge. i think you came through my subway down in draper 😂 would be cool to meet up and take some pics 🤙
Haha yep that was me! I'm always down to meet up man!
@@mainstreambuilds where’s the best place to get in touch
@@GroovyTrout do you have instagram?
Nice channel bro!
Have you considered going coil over plugs and removing the AFM, since you have an ECU Master?
Yep. Currently in the works. Just got my hall sensors and had a few extra trigger wheels made. Hopefully I can get it all done very soon.
Keep the 7ms alive they are so underestimated
I keep tossing the idea around with going 1 or 2j, but then I think why? It's a great power plant. Honestly, any engine will need a little work to produce some good power. It's a simple motor, strong, and sounds good!
@@mainstreambuilds can’t forget the torque lol I completely agree
I’m not sure if I missed but you mentioned oil squirters on the 7mgte, did you add oil squirters to your ge?? & how much did this build run you? Just got my hands on an 86 Supra and trying to map things out
Since I ended up going with forged internals, it wasn't necessary to add oil squirters. I was actually talking to a guy the other day about overall costs. I saved a bunch of money by doing all the fab stuff myself, but I'd say overall, I'm probably 8-10k.
I really like how you kept the stock look under the hood. What kind of engine oil do you use?
Thanks for checking out the vid. I've been through several different types. I'm currently running royal purple but will be switching to valvoline on my next change.
Where did you source the 90mm throttle body?
Sorry man didn't see your message. I snagged mine off ebay. I made sure it was decent quality. The xs powersports plenum will accommodate a 4 bolt 90mm throttle body. I think mine is the OBX billet 90mm body that works with the older toyota throttle position sensor.
I really liked your video
Thank you!
hey my dude, cool vid and thanks for pouring content on your build. i found me a blue 86 hardtop and purchased it yesterday! do you have a guide from going to ge to gte and if not, may you create a spreadsheet and video for noobs like me? mines a ge and overheard the engine was bored out (is doing a compression test a way to determine how much the engine was bore?). overall, i'm looking to get a nice fun street car like how you were mentioning. also, glad to say i'm officially in the supra gang:)
Sorry it's been so long my man! Hopefully all is well and your able to cruise around. I'd be more than happy to make a list for you. I'm sure with how much time has passed you might have already done some research on your own. Let me know if you still need this info and I can do a short video. These motors are actually pretty fun to tinker with and might seem a little complex but they are very simple.
Congrats on the purchase! You will not be disappointed.
Looks amazing. I own a 1990 NA 5speed, This is exactly how I want my 7MGe to look but I’m good with out the turbo I just want a cleaner look like what you did with the intake. Also good idea for the valve covers by making look flat on top , I’m not a big fan of how they look with the dip in the middle . Love the car . Can’t wait to see it through the changes of the ecu and also see the power numbers . Keep the Vids coming . All Mk3 and supra owners need this type of content to keep us motivated to work on our own cars. Best of luck with the channel . I’m here to stay
Thanks man! I really appreciate the feedback. I agree with you as far as the lack of mk3 supra content on RUclips. I hope my videos are informative and help.
@@mainstreambuilds yea man you’re the only one I know of that explains everything thoroughly . I literally was looking for some content today to get motivated to work on the Mk3 and I came across your Channel. Glad I did hehe , good look with everything man.
Well done!
7MGE. End GTE 👍
Hey just coming across your channel and just wondering if you’ve had the same problem as me, so this is my 2nd mk3 but this one is new which is a 87 with a 91 swap and a warlboro 255, but for some reason whenever you start the car and the engine is warm it tends to need a rev typically up to 2k or it’ll stall, or if I’m just chillin in neutral and rev it under 2k it’ll start to stall out and I have to rev it back to life, if anyone else has had this issue lmk
I've heard of other people having this issue as well. I haven't experienced this personally, but I wonder if is making the car run rich so the 02 sensor is telling the ecu to kill power. Do you have the factory fuel pressure regulator and fuel damper?
@@mainstreambuilds yes I have a factory regulator and fuel rail
@@mainstreambuilds I noticed that the cam angle sensor had these cheap crimp on connectors so I replaced those and soldered the wires and it seemed to remedy the random dying out a little but it’ll occasionally come back but it completely fixed the occasional misfire i was having
Good job.
Thank you!
Good to see some 7M love out there still!!! What manifold do are you running? Looks good man!
Thanks man! And thanks for checking out my channel. The intake manifold is an XS powersports plenum welded to the 7m runners. The plenum kit is for a 2jzge. It worked out perfect, looks and sounds amazing.
@@mainstreambuilds my bad, I meant what exhaust manifold haha
@Nick McDermott haha everyone asks about the intake manifold so I just assumed. We tig welded the manifold using weld els from treadstoneperformance.com it's a T3 manifold so I'm sure I'm a little limited on power, but it gets the job done. Its fitted with a 38mm wastegate, but that will be upgraded eventually.
I have a '87 Toyota Supra one owner car. I have had it parked for a good while, and now trying to get it started again. Do you know it the 87 has a crankshaft sensor, and where it is located?
@ManuelLopez-ti9od that's awesome! Get er runnin! The 7mge doesn't have a crank sensor. The only "sensor" You have is the distributor. It will run off the cam and deliver spark through the rotar inside the distributor. My guess if it's not running the fuel is probably bad or clogged injectors. I'd run through and just check spark on each spark plug as you crank it over. I'm willing to bet it's something with fuel. Injectors, fuel pump, fuel filter....etc
@mainstreambuilds Thank you for your feedback.
@@mainstreambuilds I have another question if you would be so kind to answer. Do you know where the fuel inlet line is to the fuel rail on the '87 Supra? I have a line (fuel-?) at the end of the fuel rail near front of car that is connected to some device screwed into the fuel rail; I have a line (fuel-?) 2/3rds back towards the firewall; and I have a line (fuel-?) that is at the end of the fuel rail closest to firewall screwed into another similar to front device. Not sure which of these is the fuel inlet line. I am using a fuel injector cleaning kit to bypass the gas tank.
@ManuelLopez-ti9od not a problem at all! So the one at the front of the rail is going to be your return to the tank and the thing screwed into the rail with the banjo fitting is a small fuel pressure regulator. The fitting in the middle of the two towards the back of the rail us the feed for the cold start injector. The fitting at the very back of the rail will be the inlet from the tank to the fuel rail. You could pop the back fitting off and place in a bucket or some sort of a catch and then turn the motor over and see if any fuel comes out of that fitting. Again be careful as you will be dealing with pressurized fuel. Also the little weird fitting thing on the back of the rail where the fuel comes in is a fuel damper to help prevent a little fuel surge.
@@mainstreambuilds Thank you for your feedback. I appreciate it. I will try to use my fuel injectors cleaning device to connect to the back inlet fuel line to pressurize and bypass filthy gas tank.
i have a 7m-ge toyota cressida with arp headstuds and brand new head gasket but i keep hearing theyre too expensive to be worth it over a jz and im considering a swap.
I definitely contemplated doing the swap myself but I wanted to try and keep it "original". I definitely want to turn mine up more. Keep me posted on what you do!
@@mainstreambuilds for sure will, i have another project though. for yours, has it been reliable? are parts cheap?
@lucioucz oh I super content with my 7M. It holds great power and I haven't had to throw a ton of money at it. I got the block and head machined a few years ago and haven't had any issues. The forged internals didn't cost an arm and a leg either. In my opinion it's a great motor to learn on.
My build is remarkably similar to yours!
@@ImpactMotorZ add me on instagram. I'd love to see it!
Do you still have the MK3 ? I just recently bought one and I am taking out the engine to get it rebuilt, do you have any recommendations that I can use to start ?
@erosa5025 sure do! Actually just got back from a short drive. If you are in the salt lake area, I used a company called pro machine in murray. They have been around for a looong time. They build a lot of supra motors for the local guys. Highly recommend!
If your running a standalone ECU, why are you still using the AFM ?
@@joelcr250 I'm not now. This was an older video. I need to do an updated overview of the car now. AFM has found a new home haha.
Considering this video is 9 months ago, did you ever install your ecu into the stock wiring harness? Which ecu did you use and what were some changes you made to the stock harness? Personally Im gonna have to find an aem or pro efi ecu since tuners around here use that, but I need an idea of what changes Im looking at before I do my own na-t project. I love the build by the way the FFIM really modernizes the engine bays of these cars.
Yeah I've been slacking on the uploads and haven't given a recent update on this. I decided to bag the megasquirt and went with the ecumaster EMU classic. I finished wiring all the inputs and ran into an issue with the ignition signal. I got the adapter harness from ecumaster and I guess the wiring isn't correct so I've been needing to figure that out. So far it's been super easy to work with and I would recommend it. Another guy I know is running 500hp on his 7m with the ecumaster.
I will try to do an update video on this soon.
Hey I was curious if you had any issues running the pnp adapter for the ecumasters standalone. I know the GE and GTE harnesses have a slightly different pinout, and they don't have a GE adapter. It's really the only thing that's kept me from buying it. I have GTE harnesses but they're hacked and my GE is mint so I'd prefer not to change it if I don't have to.
So I havent had to repin anything on my actual harness. All the cutting and splicing is done on the pnp adapter and ecumasters has done a great job with showing you how to add sensors and how to test everything on the ecumasters tuning software. If you do need to move the jumper wires, ecumasters provides great documentation on how to do it. I made sure to get the pnp for the ge (yellow connector not the grey) I haven't gotten it tuned yet but so far everything seems to be working properly through the tuning software. I've added intake air sensor, Mac valve for boost control, marlin crawler transmission speed sensor (for launch control), wired in a wide band 02 sensor, and a fuel pressure sensor. I should be getting it tuned very soon and I can give you guys some feedback.
I will do a video on my ecumasters setup. Hopefully that will give everyone a better idea. I'd definitely recommend it. Great unit for a decent price. I'm no genius when it comes to electronics and I was able to figure this out. Ecumasters has uploaded a ton of very well done videos on RUclips which give step by step instructions.
@@mainstreambuilds Ok thanks for the info. It definitely seems like the best route short of building a custom harness for any other standalone. I’m also tempted to keep my distributor and coil like you have, just curious what the power limits will be before the coil will need to be upgraded. Make sure to post videos whenever you get it tuned too!
@@_Bonez12 yeah you shouldn't need to cut anything besides the pnp. I was in the same boat as you. I even bought a separate used harness just in case but didn't end up using it. The guy tuning my car said the distributor will definitely limit the HP but it should get me around the 500hp mark I'm looking for. I will definitely keep you posted. Worse comes to worse I will drop some coin and get a trigger wheel and do a coil over plug setup.
I bought my mk3 about a year ago, it runs pretty good and it has about 200k miles, the last owner did a few cosmetic modifications but the engine is a stock 7mge and I’ve been thinking about turboing the engine. Where would you recommend I start?
Also I saw a guy on facebook market selling a 7mgte built block and I was thinking about buying it. Do you think I should?
I’m only aiming for about 320hp
It really comes down to how much you are willing to spend. A built 7mgte would obviously be better than a stock 7mge. If you are going to turbo the GE I would start out with building a decent foundation. Headgasket will most likely be your main issue. The factory headgaskets and head bolts aren't sufficient enough for boost. I'd look at maybe getting block and head resurfaced and run a metal headgasket with arp studs. Unfortunately I learned the hard way and kept fixing little bits here and there when I should have just pulled the motor out and installed a metal headgasket, studs, forged rods and pistons, and a shimmed oil pump.
It can definitely be done, it just needs a little work 320 isn't insane, but it is roughly 100hp more than factory. Doesn't seem like a lot but it can take some work to get there. I hope you do it! I love hearing people experimenting with the 7M and making it what it should be! Keep me posted.
I recently bought an '88 7M-GE and would like to turbo it in the future. Right now its not in running condition due to a broken timing belt issue. Do you have any advice for getting it working again?
I will be doing another video soon on how to turbo the 7m. Hopefully I can crank that out soon. As for the timing belt issue, if there is no internal damage from the belt breaking and pistons hitting valves. If all is good you could reset timing and throw in another timing belt. I would pull the spark plugs and crank the engine over by hand and see if it seizes or locks up during the rotation. The last thing you want is a catastrophic failure.
@@mainstreambuilds Thanks! I'm new to the car sphere but want to get into it as a project car. I do have some mechanical know how and have friends who are professional mechanics. Is there and online group or something for the mk3 supra I could join to learn more about this car?
@CaptainAwsome73 oh very nice. These cars are relatively simple to work on. You could always scroll through supra forums and get some good info there. Some of the info can be pretty old but still worth scrolling through.
I love how you didn't just swap over to the 7mgte electronics like most people do. I plan to do the same to mine. Had mine since I was 16.
It actually works pretty well. Low boost and 550cc injectors, it seems pretty happy. I will eventually run a trigger wheel setup with coil over plugs just so it's more efficient, but I've been running it on stock electronics for a while and haven't had any issues.
I hope to pass down my supras to my son someday
I've always loved this car. I'm 33 years old now and I remember my dad dropping me off at school in "the supra". I will try and keep this car in my family as long as possible. I still joke with my wife about how much attention this car gets. She experienced it first hand when I was stopped at the gas station and the kid wanted pictures and videos and kept saying "I can't believe I'm seeing this". His reaction made it all worth it. Hopefully you can keep your supra in your family for a very long time.
My dad is also giving me his supra and its completely stock besides repaired parts, and I want to ask if you think it's worth it to put a turbo on the original 7M-GE?. I plan to rebuild the engine anyways but finding parts is hard and I'm not sure if I should take the risk and put a turbo.
@amazinjason4959 that's awesome! So that's what I did, put a turbo on my GE. The only thing you need to be mindful of is that stock head gasket and head bolts. They won't hold boost and will pop pretty easily. I'd have the the block and head decked by a machine shop and throw in a metal headgasket with some ARP head studs.
@amazinjason4959 It can definitely be done and I highly recommend it. Turbos are everything haha! If you have questions along the way feel free to ask.
@@mainstreambuilds Thanks, and I'm guessing by adding a turbo there will be new wiring correct?
@amazinjason4959 Nope, only if you decide to run a bigger fuel pump, injectors, wideband......etc. I ran my car on factory wiring and ecu. I wired in 550cc injectors, bigger fuel pump, and wideband to watch AFRs. Obviously it's ideal to run a standalone so it can be tuned and run efficiently.
my dad is finally giving me his stock 7mgte mk3. it was a junkyard supra from what he told me and brought it back to some life. still not in its best state and has lots of issues. when braking it stutters and doesnt brake all the way, just kinda goes in and out until it fully stops. another issue is when turning the steering wheel clockwise it starts to make a rattling noise in the front left wheel. I have lots of plans for it but i atleast want to make it drivable as of now. Im pretty clueless when it comes to working on a car but im determined to fix this beauty. what should i start with ?
Thanks for sharing man! That's awesome! So to me it sounds like some new brake rotors might be needed. I'd also check the brake master cylinder and even the slave cylinder. It may have a small leak in the brake system from it sitting. I'd bleed the system and see if that fixes your issues. As for the rattling that could be a wheel bearing which isn't too difficult to replace. I personally would get that stuff sorted out before throwing performance stuff at it.
If you have the money and time I'd start with a metal head gasket and ARP head studs. The engine will require some machining so the gasket completely seals. The head and block will need to be resurfaced in order for this to work. This process will be a good base to start with. The 7MGTE/GE are notorious for blowing headgaskets and can cause some major damage when they fail.
You could also do some simple things such as replacing the mass air flow sensor with the Lexus mass air flow sensor, do the is300 coil pack conversion, and going with slightly larger fuel injectors. The CT26 turbo is great but very limited when it comes to increasing boost. You could get the CT26 that has been modified to flow a little more air. You could also do an exhaust with a larger downpipe and even a slightly larger intercooler. These cars have a lot of potential the hardest part is figuring out where to start.
Hope this helps steer you in the right direction.
@@mainstreambuilds thanks for all this information. Im 21 and it looks like ill be dumping a fair amount of money until im satisfied. Please dont disappear because you are one of the few 7mgte youtubers that i look forward to watching and learning
@@keven6691 thanks man I really appreciate it!! I will for sure continue making videos!
so what all did you do to the GE to get it turbo ready? What are all your parts?
in other words, you got any parts that you think I could turbo this on the cheap end? I cant really weld an intake manifold but i can drill into the oil pan and such
I'm actually planning on doing a video on this soon when I go to swap out turbos. It's not super involved. I had the bottom end built to support the boost and not huck a rod, cometic metal headgasket, arp head studs, wiseco pistons, eagle rods, and arp main and rod bolts.
@@mainstreambuilds I saw that in the video, I just gotta keep saving up but soon I'm gonna get there!
@Crispified98 I wanted a good base to build on. The 7M can definitely hold the power with a little work. In my opinion it's worth building. Like 1j and 2js the 7ms are now going up in proce quite a bit and worth hanging on to.
Beautiful car. Mk3 Supra owner myself and interested in seeing your seating setup. What kind of brackets/sliders are you using for your seats?
So both my seats are stiff back (don't recline). I used the corbeau solid brackets. Once I did my roll cage I couldn't slide my seats back and forth. Corbeau sells the brackets specifically for our cars. I can do a short video talking about them if you are interested.
@@mainstreambuilds I was hoping you had a different bracket because I bought a set of Corbeau RRX’s not too long ago with the Corbeau sliders and brackets but it made me sit too high. Even without the sliders I didn’t sit right. I was going to buy another set of seat brackets from a different manufacturer but after looking at it, there can’t be much of a difference with another brand either. I’m guessing the seats possibly play a role in seating position as well. It would be nice to see how yours is mounted though. 👍
@@shuexiong2620 I have the fx1s and I had the same issue. They would sit way too high. The non-sliding brackets are a lot lower but they are fixed and won't move. The brackets definitely have enough material to drill the holes forward or back to adjust the seat if needed. I will do a video on it for ya. I've had other people asking about them too.
A '92 fell into my lap recently. No drivetrain at all, any advice or help is appreciated.
Lucky! Don't let go of it! As for advice I'd figure out what you want to do with the car. Do you want it for a few around town car, drift car, drag car? That will help with pointing you in the right direction for what power plant would be best. The possibilities are endless, however parts are getting harder to find and expensive. Try to find what you need and get building! These cars are so much fun and pretty easy to work on.
My mk3 supra is runnin arp head studs and cometic head gasket as well😎😎
is it the 7mgte? and how has it been? what should i know before starting. gonna start building mine this month
@@Confestus its going great! Making 352whp and 496nm torque, running healthy on a pretty basic setup. Hasn't given me much trouble to be honest, if you have any troble with your build contact me! Glad to hear you are starting a great project like this car is!
did you delete the ABS system ? I don't see it. and if you did can you list the lines that need to be purchased ??
My model did not come with ABS. I think driftmotion.com has an ABS delete kit.
Hello,
Which oil pump?
Thanks,
Factory oil pump that has been shimmed to increase the pressure.
This is so epic
Sorry but did the Camry throttle cable come from an I4 or the V6?
1992-1995 toyota camry 4 cylinder.
when you say over revving how high? I rev mine to 7,200rpm.
I was being dumb and red lining it a lot because I thought it sounded cool ha.
@@mainstreambuilds gotcha lol
What intake manifold is that ?
This is a custom intake. 2jzgte plenum welded to the 7m runners.
Is a 61 mill turbo too big for a 7m
Naaa. If anything it might be a little on the small side. I have another dual ball bearing turbo with a larger turbine housing I may throw on eventually. The holset I have now is pretty limited and will max out fairly quickly.
Where did your FFIM came from?
This is a one of a kind home built. 2jzge ffim bolt on for the Lexus is300 (usdm) we welded the 7m cast runners onto the intake plenum and ported it.
@@mainstreambuilds thanks dude!!! And where did you get your throttle from?
@@arne8837 you bet man! I got just a generic 90mm billet body from ebay.
Hey umm does 7m reliable enough for daily Comparing 1jz?
Everyone kinda has their own opinions when it comes to this topic. A lot of people will say the 1jz is far more reliable. I've driven my supra from Utah to Nevada several times and the only issue I had was my AC compressor went out. Other than that the car ran flawlessly. I've also seen a 1jz supra over heat and stop running. It had to be towed to the next town. In my opinion both motors are great. I'd for sure have the 7m block decked and head resurfaced and throw in a metal headgasket with ARP studs. I had this done many years ago and drove the supra as a daily for a while with no issues. Whenever I get asked this question I usually respond with "what is your goal for the car?". Depending on what you want to do with the car you may need some deep pockets. I put quite a bit of money in my car but I enjoy it and drive the s*** out of it.
@@mainstreambuilds ah I see, thanks for sharing your experience :D to be honest i love A70 and im having a plan to bought one, the only problems that i had right now was umm you know the engine itself 7M that giving me a doubts, and many people owning A70 mostly swap the 7M with 1 or 2JZ engine, could you gave me some advice? maybe a guide about purchasing A70? :D
@@mainstreambuilds i'm seriously fallin love with A70 supra but doesn't know how to bought the good conditions A70,
Anyway love your videos :)

Yeah pretty funny
My buddy did a Turbo on his all motor 2jz on the Lexus and I’ll tell ya you don’t need a 7M or 2j that comes Turbo when you can make one
Yes! Very true. Slap a turbo on it and have fun! People get too caught up in all the turbo vs non-turbo stuff. If it makes turbo noises and brings happiness then goal accomplished!
@@mainstreambuilds because people are gonna remove the stock turbo anyway as well
@@kaybevang536 that's so true. First thing my buddy did on his 1j was pull the stock turbo and ma if old before he even started the swap.
@@mainstreambuilds my buddies Lexus IS the USDM Altezza with the all motor version of the 2J it’s similar

This video was fucking badass dude
Thanks man! I plan on doing another one with all the updates. This video was one of my first ones and it wasn't my best haha.
