I HAVE A 2007 2.0 MAZDA3..I did a swap with a 2007 2.3 engine ..but wen the car comes to a regular temperature .the car stalls and don't want to run.i really need help...
the 2006 and up is a pretty direct swap with some replacements from 2.5 to 2.3. But overall its a pretty easy going swap compared to the more intermediate swaps
This swap also works for the Mazda 5, but the 2006-2007 5 has the same camshaft issue that your early Mazda 3 does - you need to use the older intake cam. I opted to buy a new one from Mazda since my donor engine had only 10K miles on it and I didnt want to try and swap the gear. I have done two of these swaps into Mazda 5s now and would definitely do it again. The intake adapter (available on ebay) is definitely worth the $60 it costs. I painted it black as I live in a state with emissions inspection and technically this swap and this spacer arent legal. Painting the adapter spacer black makes it look like part of the intake manifold and both of my swapped cars went through inspection without a second glance.
Very, very helpful detailed summary of everything involved in swapping engines. Thank you very much. Now I think I'll skip the swap! LOL I'm advanced DIY'er, but my '04 M3 is my only daily driver. So a weekend swap I can handle, but this... no. Thanks again. Very helpful info to make the decision.
This was a good watch. I learned alot. You can't buy time, depending on how you value your time, I recommend staying with the 2.3l personally. I hope your son enjoys the car. I love mine!
I am planning to do this swap with my son’s 2006 Mazda 3. It has a rod bearing knock that was due to oil starvation. I getting a 2.5 engine from a 2011 Mazda 3 that is fully dressed with over 100K kms. Will this swap entail all the procedures you mentioned like stripping the 2.5 down and transferring parts from the 2.3 or is it a direct swap since it’s a Mazda engine and not a ford? Most searches I’ve seen is the fusion engine swap so far. Thanks in advance.
It's been a while since I've done my swap so I'm a little rusty. Keep that in mind. If I recall correctly, with the 2011 Mazda engine, it should be a direct swap into the 2006. I believe the camshaft timing wheels are the same number of teeth, and that the oil pan and intake manifold are the same. Mazda to Mazda is the easiest swap and the Fusion swap is the one that requires the stripping down and swapping of parts that I talk about in the video. I advise you to visit Mazda3Forums.com for further swap details and to double check.
Baxrok2 thank you for the info. I did go to Mazda forums to check and even started a thread regarding this swap, but unfortunately I did not get any answers. Thanks again!
@@ianrafols2970 I think you'll be okay. Verify the following just to be sure. 1) The number of teeth on the cam shaft sensor wheels are the same. 2) The oil pan is the same. 3) The intake manifold is the same. I think that in 2006, the cam sensor wheel changed and so it should be the same as the 2011 engine. The oil pan should have the space for the A/C compressor. The intake manifold, you can keep from the 2011 and it should be identical including the flap solenoids and throttle body mounting holes.
Ok this actually seems like a straight forward swap. Nothing different than any long block you get. As far as cam just find timing Mark on cam, point straight up, Mark both and swap. This is an easy weekend project. Got my brothers engine out in 2 hours through the bottom.
04 Mazda to 09 fusion Changed the timing cover, degreed the cam cog and swapped cam sensor cog to the 2.3, using the 2.3 flywheel and crank sensor. Car will fire one time and shoot fuel one time and then shuts down
I read someone else with that issue had put the cam cog on backwards. Is your crank sensor aligned correctly, I believe I remember it needing to be aligned correctly. Did you ever fix it?
The cog isnt set correctly relative to the camshaft - this is normal when it cant get the cam signal correct. It fires once and when it doesnt get he correct signal it shuts off.
Ahh I really wanted this engine...I hear it doesn’t have engine oil burning probs down the road. My Mazda is also 08 and I noticed that my valve cover has the dipstick there so I’m sure there’s even more diff to look out for like the timing wheel, Oil pan, etc...
What about put the fusion 2.5 engine to fusion 1.5 ecoboost (engine fairlure) and then install a turbo kit there. Simplest way coz i need need daily car. What do ya think about that?
Thank you. This was very informative. I think I’ll just bore out a 2.3 block. I was being told the 2.5 was a simple drop in and I knew there was no way that was correct
Baxrok2 the 2.3 engine I have the previous own never changed the oil and it lost the rod bearing is cylinder 4 so I’m just going to rebuild the whole thing and slap a 6 speed manual transmission on it. The oil filter, can I take the screw on type and replace the cartridge type with it?
Sounds like a good plan! Not sure about the oil filter. Visit Mazda3Forums.com for that info. If it can be done, somebody has most likely done it and made a DIY on it! Good luck!
That 2.5 engine is the 5 cylinder Volvo engine isn't it? Over here in the UK they make about 220 HP in standard form. When all the parts are swapped over from the 2.3 I imagine the new set up will at least match what the origonal Speed 3's horse power was (274 in North America) ?
Why would you swap n a motor that was only .2 of a liter bigger? I bet it was because the 2.5 is more available? I'm looking for a 2.3 for an 05 mazda 3 and so far the only ones I find are newer and nobody says they will fit., but no body knows why. I could get one at "Bucks auto wrecking" ( like pick a part) but don't look forward to laying on the ground without an impact and paying $300 for something with unknown Kms.
Mazda motors are three times as expensive and harder to find. The Ford option is the least expensive and easiest to find. First gen Mazdas can use up to a 2011 Ford block but it's a process to fit all the Mazda parts back on. The easiest swap is the 2006 Mazdas and up because the camshaft timing wheels are the same as the Ford.
Cheaper, more available, more reliable, can find them from newer cars so less mileage. The power bump isn't huge, but it's there. And the additional torque/power in the mid-low range makes it especially appealing on cars with 4 speed autos.
Hey wondering if you could answer a question for me. Which engine should I get? The one with oval variable valve timing solenoid connector? Or a rectangle variable valve timing solenoid connector? Thanks
Curious, do the heads line up? Under a quick google search that partially brought me here I thought I saw the blocks are the same so you could just do the heads. -peace
Ever run into an axle on the driver’s side being hard to get out from the transmission end? I’ve got more than half my 2.3 out but that driver’s side axle is throwing me for a loop. FYI, my 3 is a 2007.
Baxrok2 Thanks for the encouragement, I did manage to get it off without damaging it...I think. I tried the FWD CV Axle Puller set up from Auto Zone, basically a very big crows foot that bolts onto an air hammer but that did nothing. Even tried throwing a chain around it and using my come along attached to my squat rack with all the weights on it...that was total shade tree mechanic but I braced it properly as not to pull the car of the jacks and no dice. Finally, I used a very big adjustable crescent wrench which I was able to stabilize perfectly over a bolt on the transmission case and a heavy hammer. Couple good wracks and it came out. Only thing is, there’s a an open ring around a slot near the end of the axle that came off with it. Not sure if that also was supposed to come out but I don’t see how you couple possibly get the axle off without that coming out too. You think that’s normal?
How hard will it be to pull an engine from a 2006 mazda3 while in a junkyard with gravel on the ground....I watched a video of an engine pull by a dealer with a car lift and an engine cart (the engine came out the bottom).....the junkyard does have a A-frame engine puller on wheels with a chain fall......
Most JY pullers have the large pneumatic tires which make it easier to move them over gravel. Unfortunately, they are large and heavy and hard to move. Just bring a few friends for help! Good luck.
I have a 06 mazda 6 2.3 4 cyl w frame damage on the passenger side (Was Tboned), Just installed a new Radiator, AC Compressor, Belts, And we put in a low mile jdm 5 speed trans w new clutch. I want to swap everything from my car into a clean 03 mazda 6 w a v6 5 speed. Is this a hard swap it sounds pretty simple? Any advice would be greatly appreciated. My mechanic has a full access garage w lift so just wanna know if its worth it in my situation.
I own two Mazda 6's a 2003 and a 2006. However, I've never done a swap on a 6, so I won't be much help. Going from a V6 to a 4 in my opinion would be a challenge if not impossible. Wiring, PCM, hoses, etc will all be different. I could certainly be wrong but if I were you I'd do a very close inspection of every component before considering the swap. For more info you can go to a Mazda 6 forum online to see if anyone has done this kind of a swap. Good luck!
The question I have for you..... Would you do this again? And.... Would you consider using a different transmission? I feel like the 5 speed isn't tall enough and you could get better mileage and comfort at highway speeds. But, not sure if it's worth the additional cost/time.
I would not do it again. I did it because it was something that I had always wanted to do. The best way to do it is to get a Mazda 2.3 engine and do the swap. You could easily do it in a weekend. Unfortunately, the 2.3 is a crappy engine and they are crazy expensive if you can even find one. The 2.5 swap is a pain in the ass to be honest and it was too expensive in the end. I wouldn't have considered swapping to another transmission. We liked the manual.
Great series thanks for the effort. I am in the midst of replacing an oil pan on my son's 3 with the 2.0L after an "off road" mishap. It is a 2008, and the book says front engine cover has to come off to remove the pan. 2010 forward docs don't mention front cover removal. It looks like there are 4 small 7mm bolts pretty shallow through the front cover into the pan. It would seem to me if I just take out those 4 bolts (and of course the remaining pan bolts) I should be able to get the old pan off an new one on. Was that your experience? What did you use for silicone to reseal? I assume there is no real pan gasket aside from the silicone. Thanks!
During my swap, I had the engine out and the transmission off so it's hard for me to say. So, I'm purely speculating here! I can't guarantee anything since I've never done what you are attempting to do. Understand that please. You're in a real jam. I agree about the bolts through the timing cover into the pan and the other pan bolts. I'm guessing that you have the engine in and the trans on. In that case, there is a lip roughly 5mm that sticks out at the rear of the pan which might prevent you from dropping the pan straight down past the trans housing. On the other hand, if you can drop the pan down, past the timing cover, you may be able to move it forward a bit to clear the trans housing. Hopefully, the pulley won't be in the way preventing you from moving it forward. The big problem will be on reassembly since you'll have to seal everything up! That will be quite a challenge since you can't slide the pan directly into place and not disturb the gasket maker material. This will be particularly true at the timing cover since you'll essentially be sealing the pan to the block and the timing cover at the same time. Quite the challenge. At the very least, in order to attempt this, you'd want to remove the trans to have better access. That way, you can put the pan in while going in towards the timing cover and up towards the block at the same time. In my opinion, even then, this will be a very tough to do properly without having oil leaks. Let us know what you decide to do and how it goes. No, there is no oil pan or timing cover gasket. You will need to use Permatex Ultra-Gray to seal things up. Don't forget to allow some time for it to cure before exposing it to fluids.
Well I got it off, came off pretty straight forward. Had to remove the lower motor mount for pan to clear. My new pan should be here later this week, I'll try a couple "dry fits" to see how I can best get it on and maintain a proper seal. Fingers crossed!! Thanks for the quick reply, and a shout out to Eric and Ivan at SMA + PHAD from whom I've learned so much to even think about attempting this!!
Fantastic! Nice work. I went by the manual and used an approximately 4mm wide bead of the Permatex all around the pan and timing cover. Pay close attention to the area around the rear main seal. If you have a manual trans and you have an oil leak back there you may contaminate your clutch. Sounds like you're doing a great job and will be able to pull this off. Let us know how it goes. Good luck! Oh yeah, those guys are truly an inspiration.
Success! Got the new pan on without too much trouble. Read a Mazda TSB that said loosen each of the trans bolts one turn to allow for a tiny bit more clearance. Waiting for permatex to cure, we'll know for sure tomorrow.
Outstanding! That's great. Hopefully no major leaks. Let us know, or heck, make a video and show us! The fact that you can remove the pan like that makes me wonder if one can replace piston rings without engine removal? You know, like Ivan did on his friends Prism and like the Toyota guys do on the early Corollas. Remove pan, remove head, remove pistons, replace rings, reassemble. Hmmm.
I'm not sure as I've never done the research on it. I'd advise you to go to Mazda3Forums.com and search there for answers. If it can be done, someone there has surely done it.
Do you think a 05 focus 2.0l duratec 5 speed to a fusion 2.5l would be a similar swap? This is for a hill climb car so it would be getting aftermarket cams, intake, exhaust, and an egr delete. Again this would be for a racecar so there will be some stuff that is eliminated or replaced with aftermarket parts.
Yes, I do. You can visit the Ford Fusion/Focus forums for more information. Those guys are doing pretty much the same thing as the Mazda guys when it comes to the engine swaps so there are threads with the same kind of information. I think that some guys just use the 2.5 short block and put the 2.0 heads on it. Good luck!
It's been a while since I did the swap, but if I recall correctly the 2.3 and 2.5 exhaust ports and bolt pattern are the same. However, I don't know if the 2.3 Turbo head is the same as the 2.3/2.5 heads. For that info, you'd probably want to go to Mazda3Forums.com. If it can be done, someone there has probably done it.
Baxrok2 thanks for the quick response. I contacted so many performance companies and no luck for my 2012 mazda3 s grand touring (2.5l). Luckily I contacted mazda today and they will have an answer for me by next day.
No. It's not necessary. Pull the 2.3 and put in the 2.5. 2.3 wiring and PCM are good to go. Why do something that doesn't need to be done and may in fact cause problems.
Baxrok2 thanks for your input. my question was. if i have am 05 mazda can i get the ecu from and 09 and the wiring harness. and swap them and then continue the swap as a 09mazda 3 to 2.5 fusion engine. since it seems the major issue is the cam style. and if you Have an 09 ecu it should be looking for an fusion style cam. id rather not mess with the timing unless i have to. i have an 05 my brother has an 09 both hopefully will get fusion swaps
I don't know if you can do it that way. The challenge is that you don't know exactly the small subtle electronic & wiring differences between the 05 and 09. Maybe there aren't any differences but you'd have to try it to find out. So, you have a tradeoff. You can replace the 09 timing wheel with the 05 wheel on the intake cam or gamble and experiment with the PCM swap. If you do the timing wheel swap and the set the timing with the 05 PCM, then you're done. If you do the 09 PCM and engine swap then you may have to diagnose potential electrical and computer problems. I advise you to join Mazda3Forums.com and search for the 2.3 to 2.5 engine swap threads. If it can be done, the guys will have posted step by step how to do it. I haven't visited the site lately and have not kept up with what they might be doing. Good luck and let me know what you find out!
Greetings. I'm sorry but I don't have any experience with the Ford Fiesta vehicles. Go to a Ford Fiesta forum on the internet for answers to your question. Good luck!
I was wondering if anyone has done this swap except with a Gen2 Mazda 2.3L? I may try to tackle it in 2009 Mazda5 van with a bad engine. Just wondering if anyone has any leads on the discrepancies between Gen1 vs Gen2 swap. Anything is appreciated!
Justin, I advise you to go to Mazda3Forums.com for details. If it can be done, somebody there has probably done it or knows why it can't be done. Good luck.
@@davidgonzalez-wz5sl IMO, an engine that uses that much oil is already bad because it can leave you stranded. If it's your daily driver then that's something to think about. Also, I have never worked on a turbo engine so I'm not 100% aware of all of the additional details of a Speed 3 swap. As far as I know, the 2.5 will work in place of the 2.3 in the Speed. However, I strongly encourage you to visit Mazda3Forums.com or a Speed 3 specific forum for the important details of a Speed 3 2.3 to 2.5 swap.
@@davidgonzalez-wz5sl you can swap the 2.5 in the speed. You need to swap the disi head and tee off the filter housing for the oil feed and drill in the oil pan for the oil return
Amigo muchas gracias tu vídeo fue de mucha ayuda para mí ya que estoy en el proceso de hacer este swap en miazda 3 2.3, muchas gracias de verdad te ganastes un seguidor de mi parte
No, they don't. It's actually very straight forward. You use the slot in the camshaft as a reference point. You'll see that the tips of the timing wheel will line up with the slot. Put a straightedge into the slot and you'll see that the tip of the timing wheel lines up almost perfectly. If you do it you should make a video for others to see how it's done!
Thank you for the response and for the detailed videos you made. They help me understand what's really involved in this swap which I'm considering for my 06 Mazda 5. I'm sure you'll get quite a few more views out of me as I decide whether to tackle it and then if/when I do it.
If you have an 06 you shouldn't have to change the timing wheel. It's been a while but I'm pretty sure the 06's have the five tooth wheel as do the newer 2.5's!
That would be my hope but I haven't verified the exact differences between the motors in the 3 and 5. The specs are slightly different with the 5 motor being tuned for more torque. Thanks again!
swap my 2005 mazda 3 2.3l with a 2012 ford fusion 2.5l,i only swap the crank shaft pulley,timeing cover,oil pan,vavle cover from 2.3l to 2.5l and the car works fine
Really? No swapping of the cam timing gear? I've read everywhere that the engine won't even start/run like shit if you don't on 04-05s. I have an 04 I'm about to swap myself. Doing research on it right now
hey man im about to go through with this swap. can you help me out the only part as of now that im not sure about is the intake manifold situation. how do i trick the ecu to use the 2.5 manifold and also where do you get the throttle body adapter? is that all i need?
You don't trick the ECU to do anything. Just use the 2.5 manifold and you won't have any problems. You will need the TB adapter or you can use a Speed 3 TB or a 2.5 TB I think. I used the adapter kit to use the 2.3 TB with the 2.5 manifold. You can get the TB adapter kit on ebay or you can go to Mazda3Forums.com and go to the engine swap threads to find the guy who makes them. It's been a while since I did my swap but I think that's all you'll need. Don't forget the cam timing wheel if you have an '04 or and '05. Again go to Mazda3Forums and go through the swap threads for details. Also, you can watch my How Much Did It Cost video to see what I used in my swap for some more ideas. Good luck!
@@baxrok2. ive watched every one of your vids on this topic man thankss by the way. so i dont have to do anything witht the vacuum acuators in order to not get a CEL. i may end up going with a 2.5 TB from a mazda
one guy on the forum was saying i need to make the purge valve a 2 port vacuum source but he diddnt say why. any idea on that?? i asked but havent responded yet.
also you said you have to mount a solenoid on the bottom of the 2.5 intake manifold is that just like a solenoid fromthe 2.3 thats not used on the 2.5 and you just have it plugged in to make the computeer happy?
If you keep the 2.3 mani all you need is the adapter to go between the mani and the 2.5 head. Beware of vacuum leaks! All of the connections are the same. If you keep the 2.5 mani, you need the TB adapter kit and you have to keep the IMRC solenoids and vacuum actuator connected. They will no longer be needed but need to be connected to avoid CELs. You can attach the vacuum actuator to the bottom of the mani using one of the available mounting posts as I point out in the video. The TB kit comes with (should come with) the needed vacuum ports on it as well as a new nipple for the purge valve. @@Samiam_ariel
Yes, manual or automatic, it does not matter. A Mazda engine swap is the easiest way to go. Otherwise, if you use the Fusion engine, you have to do a lot of part swapping.
I put a 2011 Fusion engine in my 2005 3. For all of the details and choices you have go to HappyWrenching.com and look for the 2.3 engine swap article and blog. For more info, you can look through the info at Mazda3Forums.com. I put links to the good stuff in the description for you.
It's actually pretty easy to do but very hard to explain! Use a regular gear puller to pull it off and a press or socket and hammer to get it back on. Go to this link and look for the picture of the two camshafts and timing cogs. www.mazda3forums.com/61-powertrain-2004-2009-mazda3/647562-04-2-3l-swap-2-5l-successful.html#/ Line up the camshaft just like it is in the picture. Using the slot in the end of the camshafts as your guide, draw a horizontal line through the top edge of the slot and all the way out past the ends of the legs on the timing cog. Moving to the right side of the camshaft, you will see that the line will intersect almost perfectly with the bottom side tip of the timing cog leg that is opposite the slot. It's perfect for reference! You'll see that this is true for both camshafts and timing cogs. Line those up and you're good to go. Hope this helps and if you do it let me know how it goes!
Thank you for the response. I just purchased a 2015 Fusion engine with 10K miles for $546 out the door from a Nashville junkyard. I'm putting it in a 2004 Mazda 3 hatchback that has a manual trans. I just tore down the 2.3 tonight and marked the timing cog per your instructions. Everything you said was right on. I have a couple of other questions. I bought a adapter plate on Ebay for the intake to run the 2.3 manifold and keep it fairly stock. The intake is sludged up pretty badly and after watching your videos and reading the forum I believe I'm going to do the the Fusion intake and a Mazda 3 2.5 throttle body from Ebay. Questions: -Where did you get the adapter for the purge valve hose connection? It looks like you deleted the purge valve and have a adapter there. -Also, where would I tie in the vacuum solenoids for the old intake runner control? It looks like you tied into a T/B adapter. Where did you get that? I read about a guy using the 2.5 T/B making a vacuum manifold and tying it in with the purge valve port. Does that sound doable. -How did you tie in the brake booster hose? -Any suggestions on the brand/type of clutch kit to install? I know those are a lot of questions. Don't mean to monopolize your time. Thank you in advance.You are a wealth of knowledge. Your timing how to is great.
Yeah, I'd keep the 2.5 intake and get the 2.5 TB. Skip the intake adapter. The purge valve setup and the tie ins for the runners came with the TB adapter kit that I bought. I purchased the TB adapter kit since I hadn't really thought things through at the time. I should have bought the 2.5 TB. My swap is now a year old and honestly I'm not remembering the routing of all the lines. Sorry. I do think that you could fabricate a manifold of some sort to create a vacuum source. I'll have to look at my brake booster line to see what exactly I did with it but I don't recall doing anything special with it. If I can I'll look tomorrow. If you watch my Problems, Problems video you may be able to see all of the routing and connections at the TB. I bought my clutch off of RockAuto. I bought the Exedy (Daily Driver grade) clutch kit. $154. MZK1003. I'm happy with it. Pedal pressure is medium to light and seems a lot lighter than the stock pedal pressure. Hope this helps.
Did you notice a discrepancy in the oil level between the two dipstick locations? I left the spin on filter on the Fusion engine and blocked the oil pan dipstick hole to eliminate it on the 2.3 pan. After the install I added 4.5 quarts of synthetic oil and ran the engine. It now reads 1/4 quart over on the fusion dipstick. I was wondering if you found a difference in the two sticks as you were originally running both. I did finish the swap btw and used some of your suggestions. I swapped the cam gear according to your direction and also timed the engine using your videos for reference. I'm running the Fusion intake, valve cover, VVT solenoid, oil filter setup and '09 Mazda 6 2.5 T/B. Had to swap the VVT connector from the Fusion harness which I got with the engine thankfully. Running a M-Pac stage 1 clutch.
@@ohiojayohio9643 As far as I know, yes. However, I've never worked on a 6 and they are different from the 3's. This guy did a pretty good write up on the swap and has some good information that might help you. www.happywrenching.com/mazda/6/mazda-6-and-ford-fusion-23l-engine-swap.html
In one of my other videos I talk about the time factor. A straight Mazda 2.3 to Mazda 2.3 swap can IMO be done in a weekend. The Fusion 2.3 swap was much more involved, not to mention how I work (alone/slow/methodical), how often I worked on it (after work/weekends), the fact that it was my first swap (learning as I went), and all the bumps (parts needed, etc,) along the way. Unfortunately, this time frame also included almost three weeks of diagnostics (turned out to be that the timing was set wrong by someone I paid set it.) Total time was almost a month. Without the timing snafu it probably could have been done in half the time.
Hi, thank you for the great and detailed video! I was wondering if you could possibly help and/or point me in the right direction. I have a 2005 hatchback and wanted to look into putting a 2006 2.3L engine. I know the intake cam is different, but wondering what options I have. Thanks!
I don't know what other options you have other than options on how to deal with the different cam wheel. Some folks just use the 2005 cam on the 2006 engine and others, like me, just swap the 2005 cam wheel over onto the 2006 cam. Not many folks I know would be willing to put a worn cam into a newer engine, however if the engines are both of a similar age, mileage, and overall condition that may not be such a big deal. I put a 2011 engine with 58kmi into my car so no way I was using the old 2005 cam! For more info go to Mazda3Forums.com. If it can be done then these guys have done it!
@@baxrok2. thank you! Can the timing wheel be replaced without removing cam or messing with the timing stuff? I really don't want to go down that rabbit hole, if possible.
goZander this is the mistake I made after completing my swap. Car would crank but won’t start. A more informed DIYer questioned me on things I switched over, not realizing I should have done something with the camshaft, then figured out the timing wheels were different. Can’t believe I made it this far only to discover a (what I consider) major mistake. Now I’m trying to figure out how to correct it. Hoping Baxrok2 may have some insight to help guide me.
It sounds your son is going to have a nice car when your done. Learning is why we share and I'm sure this will help someone. I'm like you, a DIY'er who's been working on stuff since 14 but learning all the time. Especially in the world of diagnostics. Send me your address if you like because I'd like to send you one of my stickers. Merry Christmas.
No doubt. Those guys make it look easy. I'm fussing with this 1998 Chevy that won't start when it's cold outside. Right now it seems to be okay, but I don't trust the fix.
That's the rub right, confirming the fix. Experience matters and those guys have it! I actually wrote to Ivan to see if he would contract with me to work remotely. He could suggest direction and I'd do the work. No response from him so, I'm guessing that's a no. lol Oh well, I'm pressing on. Merry Christmas!
ok, i note that you said it wont be easy or as straight forward. But in my case i just want to swap the same engine from my old mazda to my new one. They are both 2.3L so would the process be as difficult or maybe less challenging?
Eduardo Duran Less challenging for sure! If you watch my video, I say clearly that a Mazda to Mazda swap can easily be done in a weekend. Good luck and let me know how it goes!
Wait a minute, you asked if the 2.5's will fit in the 2.3. I misread that. I can't say for sure since I only tried to put the 2.3's in the 2.5 and they fit. The 2.5's should fit in the 2.3 but you may have to play around with the fuel rail to get it right. Sorry, bout that.
Most people, myself included, feel that the 2.3 PCM can easily handle the 2.5 injectors. Of course, there are many factors in play so you'll basically have to experiment to be sure. I ran the 2.3 injectors in the 2.5 without a single problem so can't see why it wouldn't work the other way around.
bhadz100 I can tell you it boils down to the physical size of the passages. Putting in a 2.5 Mazda engine in place of my Mazda 2.3, the intake passages for the 2.5 are bigger so I bought an aluminum adapter with a gasket on eBay to avoid air leaks.
The 2.3 liter has 135 Hp & 153 Lbs torque. The 2.5 liter has only 119 Hp & only 146 pounds of torque! Why would you want to switch a more powerful & more fuel efficient engine for a less powerful and less fuel-efficient engine?!!
Because when your garbage 2005 2.3 fails, a 2011 2.5 is easy to get, cheap to buy, and way more reliable! lol Why wouldn't you want to! I think your HP numbers are wrong btw.
Well, yeah. I even titled it Blah, Blah, Blah as a warning. lol Surely you didn't think I'd make a video with only the 10 minutes of content that was relevant to you!!
Ehh, i rather just keep my regular 2.3l in my 2006 Mazda 3. The 7 HP extra horsepower from the 2.5L doesn't seem worth the time and headaches in doing this swap.
I HAVE A 2007 2.0 MAZDA3..I did a swap with a 2007 2.3 engine ..but wen the car comes to a regular temperature .the car stalls and don't want to run.i really need help...
the 2006 and up is a pretty direct swap with some replacements from 2.5 to 2.3. But overall its a pretty easy going swap compared to the more intermediate swaps
This swap also works for the Mazda 5, but the 2006-2007 5 has the same camshaft issue that your early Mazda 3 does - you need to use the older intake cam. I opted to buy a new one from Mazda since my donor engine had only 10K miles on it and I didnt want to try and swap the gear. I have done two of these swaps into Mazda 5s now and would definitely do it again. The intake adapter (available on ebay) is definitely worth the $60 it costs. I painted it black as I live in a state with emissions inspection and technically this swap and this spacer arent legal. Painting the adapter spacer black makes it look like part of the intake manifold and both of my swapped cars went through inspection without a second glance.
Very, very helpful detailed summary of everything involved in swapping engines. Thank you very much.
Now I think I'll skip the swap! LOL I'm advanced DIY'er, but my '04 M3 is my only daily driver. So a weekend swap I can handle, but this... no.
Thanks again. Very helpful info to make the decision.
Hey how about the mazda 2 engine swap from diesel to petrol
I think cam have extra nodgels and coil packs are different perhaps vct
This was a good watch. I learned alot. You can't buy time, depending on how you value your time, I recommend staying with the 2.3l personally. I hope your son enjoys the car. I love mine!
I am planning to do this swap with my son’s 2006 Mazda 3. It has a rod bearing knock that was due to oil starvation. I getting a 2.5 engine from a 2011 Mazda 3 that is fully dressed with over 100K kms. Will this swap entail all the procedures you mentioned like stripping the 2.5 down and transferring parts from the 2.3 or is it a direct swap since it’s a Mazda engine and not a ford? Most searches I’ve seen is the fusion engine swap so far. Thanks in advance.
It's been a while since I've done my swap so I'm a little rusty. Keep that in mind. If I recall correctly, with the 2011 Mazda engine, it should be a direct swap into the 2006. I believe the camshaft timing wheels are the same number of teeth, and that the oil pan and intake manifold are the same. Mazda to Mazda is the easiest swap and the Fusion swap is the one that requires the stripping down and swapping of parts that I talk about in the video. I advise you to visit Mazda3Forums.com for further swap details and to double check.
Baxrok2 thank you for the info. I did go to Mazda forums to check and even started a thread regarding this swap, but unfortunately I did not get any answers. Thanks again!
@@ianrafols2970 I think you'll be okay. Verify the following just to be sure. 1) The number of teeth on the cam shaft sensor wheels are the same. 2) The oil pan is the same. 3) The intake manifold is the same. I think that in 2006, the cam sensor wheel changed and so it should be the same as the 2011 engine. The oil pan should have the space for the A/C compressor. The intake manifold, you can keep from the 2011 and it should be identical including the flap solenoids and throttle body mounting holes.
Ok this actually seems like a straight forward swap. Nothing different than any long block you get. As far as cam just find timing Mark on cam, point straight up, Mark both and swap. This is an easy weekend project. Got my brothers engine out in 2 hours through the bottom.
Hi mate, will L3 auto trans will work with L5 trans?
My L5 transmission blown and can get L3 AUTo trans dirt cheap.
04 Mazda to 09 fusion
Changed the timing cover, degreed the cam cog and swapped cam sensor cog to the 2.3, using the 2.3 flywheel and crank sensor. Car will fire one time and shoot fuel one time and then shuts down
I read someone else with that issue had put the cam cog on backwards. Is your crank sensor aligned correctly, I believe I remember it needing to be aligned correctly. Did you ever fix it?
The cog isnt set correctly relative to the camshaft - this is normal when it cant get the cam signal correct. It fires once and when it doesnt get he correct signal it shuts off.
Can one do a swap of Mazda CX-7 turbo charged with a non turbo engine and if so which one? I would appreciate any leads.
No, it's not recommended. The turbo ECU isn't set up to work with the non-turbo engine. Plus I think the wiring will be different as well.
Ahh I really wanted this engine...I hear it doesn’t have engine oil burning probs down the road. My Mazda is also 08 and I noticed that my valve cover has the dipstick there so I’m sure there’s even more diff to look out for like the timing wheel, Oil pan, etc...
I have a Mazda 3 with a Z6 engine best engine of all time very straight forward easy to change belts and water pump.
What year is your Mazda? What year and model is your Z6 engine? What was needed for your swap
What about put the fusion 2.5 engine to fusion 1.5 ecoboost (engine fairlure) and then install a turbo kit there. Simplest way coz i need need daily car. What do ya think about that?
Thank you. This was very informative. I think I’ll just bore out a 2.3 block. I was being told the 2.5 was a simple drop in and I knew there was no way that was correct
Yeah, a 2.3 to 2.3 is cake. The 2.5 does need some work before being installed.
Baxrok2 the 2.3 engine I have the previous own never changed the oil and it lost the rod bearing is cylinder 4 so I’m just going to rebuild the whole thing and slap a 6 speed manual transmission on it. The oil filter, can I take the screw on type and replace the cartridge type with it?
Sounds like a good plan! Not sure about the oil filter. Visit Mazda3Forums.com for that info. If it can be done, somebody has most likely done it and made a DIY on it! Good luck!
Engine my car Mazda 3 2.3 I want to make it 2.5 what I do
How much harder would it be to swap a 2.3l or 2.5l into a 2.0l Mazda3
That 2.5 engine is the 5 cylinder Volvo engine isn't it? Over here in the UK they make about 220 HP in standard form. When all the parts are swapped over from the 2.3 I imagine the new set up will at least match what the origonal Speed 3's horse power was (274 in
North America) ?
No, the North American 2.5 engine is a 4 cylinder.
Why would you swap n a motor that was only .2 of a liter bigger? I bet it was because the 2.5 is more available? I'm looking for a 2.3 for an 05 mazda 3 and so far the only ones I find are newer and nobody says they will fit., but no body knows why. I could get one at "Bucks auto wrecking" ( like pick a part) but don't look forward to laying on the ground without an impact and paying $300 for something with unknown Kms.
Mazda motors are three times as expensive and harder to find. The Ford option is the least expensive and easiest to find. First gen Mazdas can use up to a 2011 Ford block but it's a process to fit all the Mazda parts back on. The easiest swap is the 2006 Mazdas and up because the camshaft timing wheels are the same as the Ford.
Cheaper, more available, more reliable, can find them from newer cars so less mileage. The power bump isn't huge, but it's there. And the additional torque/power in the mid-low range makes it especially appealing on cars with 4 speed autos.
Hey wondering if you could answer a question for me. Which engine should I get? The one with oval variable valve timing solenoid connector? Or a rectangle variable valve timing solenoid connector? Thanks
Curious, do the heads line up? Under a quick google search that partially brought me here I thought I saw the blocks are the same so you could just do the heads.
-peace
As far as I know, the blocks are the same but there are some minor changes to the head on the newer engines.
@@baxrok2. Thanks! You hear this all the time but the videos you made for the swap are magnificent. Great work.
Ever run into an axle on the driver’s side being hard to get out from the transmission end? I’ve got more than half my 2.3 out but that driver’s side axle is throwing me for a loop. FYI, my 3 is a 2007.
Although I didn't have any problem with mine, this is fairly common on some cars. Don't give up!
Baxrok2 Thanks for the encouragement, I did manage to get it off without damaging it...I think. I tried the FWD CV Axle Puller set up from Auto Zone, basically a very big crows foot that bolts onto an air hammer but that did nothing. Even tried throwing a chain around it and using my come along attached to my squat rack with all the weights on it...that was total shade tree mechanic but I braced it properly as not to pull the car of the jacks and no dice. Finally, I used a very big adjustable crescent wrench which I was able to stabilize perfectly over a bolt on the transmission case and a heavy hammer. Couple good wracks and it came out. Only thing is, there’s a an open ring around a slot near the end of the axle that came off with it. Not sure if that also was supposed to come out but I don’t see how you couple possibly get the axle off without that coming out too. You think that’s normal?
@@MrHevelifter Yeah, that sounds okay from what I recall. That ring is why you need a seal that has a groove in it to accept it.
How hard will it be to pull an engine from a 2006 mazda3 while in a junkyard with gravel on the ground....I watched a video of an engine pull by a dealer with a car lift and an engine cart (the engine came out the bottom).....the junkyard does have a A-frame engine puller on wheels with a chain fall......
Most JY pullers have the large pneumatic tires which make it easier to move them over gravel. Unfortunately, they are large and heavy and hard to move. Just bring a few friends for help! Good luck.
I have a 06 mazda 6 2.3 4 cyl w frame damage on the passenger side (Was Tboned), Just installed a new Radiator, AC Compressor, Belts, And we put in a low mile jdm 5 speed trans w new clutch. I want to swap everything from my car into a clean 03 mazda 6 w a v6 5 speed. Is this a hard swap it sounds pretty simple? Any advice would be greatly appreciated. My mechanic has a full access garage w lift so just wanna know if its worth it in my situation.
I own two Mazda 6's a 2003 and a 2006. However, I've never done a swap on a 6, so I won't be much help. Going from a V6 to a 4 in my opinion would be a challenge if not impossible. Wiring, PCM, hoses, etc will all be different. I could certainly be wrong but if I were you I'd do a very close inspection of every component before considering the swap. For more info you can go to a Mazda 6 forum online to see if anyone has done this kind of a swap. Good luck!
The question I have for you..... Would you do this again? And.... Would you consider using a different transmission? I feel like the 5 speed isn't tall enough and you could get better mileage and comfort at highway speeds. But, not sure if it's worth the additional cost/time.
I would not do it again. I did it because it was something that I had always wanted to do. The best way to do it is to get a Mazda 2.3 engine and do the swap. You could easily do it in a weekend. Unfortunately, the 2.3 is a crappy engine and they are crazy expensive if you can even find one. The 2.5 swap is a pain in the ass to be honest and it was too expensive in the end. I wouldn't have considered swapping to another transmission. We liked the manual.
@@baxrok2. Thanks for the response. That all makes sense. given the crappy car market right now, I'm just assessing my options....
Thanks very much for taking the time to make this.
Greetings friend, is it possible to change the 2.3 turbo of a CX-7 for the 2.5 of the Mazda 6?
Hello. I'm sorry Brayan, I don't have any experience with engine swaps on the CX-7 or Mazda 6.
Thanks a ton
Very in depth summary and it's definitely worth the watch.
Great series thanks for the effort. I am in the midst of replacing an oil pan on my son's 3 with the 2.0L after an "off road" mishap. It is a 2008, and the book says front engine cover has to come off to remove the pan. 2010 forward docs don't mention front cover removal. It looks like there are 4 small 7mm bolts pretty shallow through the front cover into the pan. It would seem to me if I just take out those 4 bolts (and of course the remaining pan bolts) I should be able to get the old pan off an new one on. Was that your experience? What did you use for silicone to reseal? I assume there is no real pan gasket aside from the silicone. Thanks!
During my swap, I had the engine out and the transmission off so it's hard for me to say. So, I'm purely speculating here! I can't guarantee anything since I've never done what you are attempting to do. Understand that please.
You're in a real jam. I agree about the bolts through the timing cover into the pan and the other pan bolts. I'm guessing that you have the engine in and the trans on. In that case, there is a lip roughly 5mm that sticks out at the rear of the pan which might prevent you from dropping the pan straight down past the trans housing. On the other hand, if you can drop the pan down, past the timing cover, you may be able to move it forward a bit to clear the trans housing. Hopefully, the pulley won't be in the way preventing you from moving it forward.
The big problem will be on reassembly since you'll have to seal everything up! That will be quite a challenge since you can't slide the pan directly into place and not disturb the gasket maker material. This will be particularly true at the timing cover since you'll essentially be sealing the pan to the block and the timing cover at the same time. Quite the challenge.
At the very least, in order to attempt this, you'd want to remove the trans to have better access. That way, you can put the pan in while going in towards the timing cover and up towards the block at the same time. In my opinion, even then, this will be a very tough to do properly without having oil leaks. Let us know what you decide to do and how it goes.
No, there is no oil pan or timing cover gasket. You will need to use Permatex Ultra-Gray to seal things up. Don't forget to allow some time for it to cure before exposing it to fluids.
Well I got it off, came off pretty straight forward. Had to remove the lower motor mount for pan to clear. My new pan should be here later this week, I'll try a couple "dry fits" to see how I can best get it on and maintain a proper seal. Fingers crossed!! Thanks for the quick reply, and a shout out to Eric and Ivan at SMA + PHAD from whom I've learned so much to even think about attempting this!!
Fantastic! Nice work. I went by the manual and used an approximately 4mm wide bead of the Permatex all around the pan and timing cover. Pay close attention to the area around the rear main seal. If you have a manual trans and you have an oil leak back there you may contaminate your clutch. Sounds like you're doing a great job and will be able to pull this off. Let us know how it goes. Good luck! Oh yeah, those guys are truly an inspiration.
Success! Got the new pan on without too much trouble. Read a Mazda TSB that said loosen each of the trans bolts one turn to allow for a tiny bit more clearance. Waiting for permatex to cure, we'll know for sure tomorrow.
Outstanding! That's great. Hopefully no major leaks. Let us know, or heck, make a video and show us!
The fact that you can remove the pan like that makes me wonder if one can replace piston rings without engine removal? You know, like Ivan did on his friends Prism and like the Toyota guys do on the early Corollas. Remove pan, remove head, remove pistons, replace rings, reassemble. Hmmm.
Hey I was wondering if I could swap out a 2.3 for a 2.0?
I'm not sure as I've never done the research on it. I'd advise you to go to Mazda3Forums.com and search there for answers. If it can be done, someone there has surely done it.
Yes
Do you think a 05 focus 2.0l duratec 5 speed to a fusion 2.5l would be a similar swap? This is for a hill climb car so it would be getting aftermarket cams, intake, exhaust, and an egr delete. Again this would be for a racecar so there will be some stuff that is eliminated or replaced with aftermarket parts.
Yes, I do. You can visit the Ford Fusion/Focus forums for more information. Those guys are doing pretty much the same thing as the Mazda guys when it comes to the engine swaps so there are threads with the same kind of information. I think that some guys just use the 2.5 short block and put the 2.0 heads on it. Good luck!
Baxrok2 will 2.5 injectors work in 2.3
Awesome video, chalked full of great info!!!! Thank you for sharing this!
So for the exhaust? You could fit the 2.3 to the 2.5, or viceversa? Then this means you can add the turbo kit from a Mazda speed3 to 2.5 engine?
It's been a while since I did the swap, but if I recall correctly the 2.3 and 2.5 exhaust ports and bolt pattern are the same. However, I don't know if the 2.3 Turbo head is the same as the 2.3/2.5 heads. For that info, you'd probably want to go to Mazda3Forums.com. If it can be done, someone there has probably done it.
Baxrok2 thanks for the quick response. I contacted so many performance companies and no luck for my 2012 mazda3 s grand touring (2.5l). Luckily I contacted mazda today and they will have an answer for me by next day.
Baxrok2 did the swap work though? And did you have the engine light come on ?
@@garudaspeaks Yeah, the swap was a total success. No lights and not a single problem.
Baxrok2 one more question: the mounts, did you use the same mounts from the 2.3 on the 2.5? Thanks
Would it have been easier to use the 2006 ecu and wiring harness? Then proceed like a standard 2.5 fusion to 06 swap?
No. It's not necessary. Pull the 2.3 and put in the 2.5. 2.3 wiring and PCM are good to go. Why do something that doesn't need to be done and may in fact cause problems.
Baxrok2 thanks for your input. my question was. if i have am 05 mazda can i get the ecu from and 09 and the wiring harness. and swap them and then continue the swap as a 09mazda 3 to 2.5 fusion engine. since it seems the major issue is the cam style. and if you Have an 09 ecu it should be looking for an fusion style cam. id rather not mess with the timing unless i have to. i have an 05 my brother has an 09 both hopefully will get fusion swaps
I don't know if you can do it that way. The challenge is that you don't know exactly the small subtle electronic & wiring differences between the 05 and 09. Maybe there aren't any differences but you'd have to try it to find out. So, you have a tradeoff. You can replace the 09 timing wheel with the 05 wheel on the intake cam or gamble and experiment with the PCM swap. If you do the timing wheel swap and the set the timing with the 05 PCM, then you're done. If you do the 09 PCM and engine swap then you may have to diagnose potential electrical and computer problems. I advise you to join Mazda3Forums.com and search for the 2.3 to 2.5 engine swap threads. If it can be done, the guys will have posted step by step how to do it. I haven't visited the site lately and have not kept up with what they might be doing. Good luck and let me know what you find out!
I haven’t watched it fully but I was wondering do you need a different computer or wiring harness when swapping?
No.
@@baxrok2. alright thankyou, one more thing do you need different motor mounts or does it line up?

I’d be willing to say no. The Fiesta seems much narrower and tighter at the nose.
I was wondering if anyone has done this swap except with a Gen2 Mazda 2.3L? I may try to tackle it in 2009 Mazda5 van with a bad engine. Just wondering if anyone has any leads on the discrepancies between Gen1 vs Gen2 swap. Anything is appreciated!
Justin, I advise you to go to Mazda3Forums.com for details. If it can be done, somebody there has probably done it or knows why it can't be done. Good luck.

The same oil consumption is happening on my speed 3, should I swap my motor or wait ?
Or wait for what?
Baxrok2 for the engine to go bad
@@davidgonzalez-wz5sl IMO, an engine that uses that much oil is already bad because it can leave you stranded. If it's your daily driver then that's something to think about. Also, I have never worked on a turbo engine so I'm not 100% aware of all of the additional details of a Speed 3 swap. As far as I know, the 2.5 will work in place of the 2.3 in the Speed. However, I strongly encourage you to visit Mazda3Forums.com or a Speed 3 specific forum for the important details of a Speed 3 2.3 to 2.5 swap.
@@davidgonzalez-wz5sl you can swap the 2.5 in the speed. You need to swap the disi head and tee off the filter housing for the oil feed and drill in the oil pan for the oil return
What gas mileage does it get after the swap?
Amigo muchas gracias tu vídeo fue de mucha ayuda para mí ya que estoy en el proceso de hacer este swap en miazda 3 2.3, muchas gracias de verdad te ganastes un seguidor de mi parte
Do any of your videos go into more detail about swapping the camshaft timing wheel and making sure you get it accurately aligned?
No, they don't. It's actually very straight forward. You use the slot in the camshaft as a reference point. You'll see that the tips of the timing wheel will line up with the slot. Put a straightedge into the slot and you'll see that the tip of the timing wheel lines up almost perfectly. If you do it you should make a video for others to see how it's done!
Thank you for the response and for the detailed videos you made. They help me understand what's really involved in this swap which I'm considering for my 06 Mazda 5. I'm sure you'll get quite a few more views out of me as I decide whether to tackle it and then if/when I do it.
If you have an 06 you shouldn't have to change the timing wheel. It's been a while but I'm pretty sure the 06's have the five tooth wheel as do the newer 2.5's!
That would be my hope but I haven't verified the exact differences between the motors in the 3 and 5. The specs are slightly different with the 5 motor being tuned for more torque. Thanks again!
Does this engine consume too much oil do you have to add oil every other week
Yes, this generation of engines is notorious for oil consumption and rod knock issues. I was adding a quart of oil every 400 miles!
swap my 2005 mazda 3 2.3l with a 2012 ford fusion 2.5l,i only swap the crank shaft pulley,timeing cover,oil pan,vavle cover from 2.3l to 2.5l and the car works fine
Excellent information. Thanks!
Next stage is turbo kit. Sooner or later 😁
Really? No swapping of the cam timing gear? I've read everywhere that the engine won't even start/run like shit if you don't on 04-05s. I have an 04 I'm about to swap myself. Doing research on it right now
I'm about to tackle this project within then next week. Same exact car, 2005. Where do you suggest buying/finding an engine?
There are several options. Local salvage yards, eBay, or cars for sale on Craigslist etc. I bought locally at a place that sells engines.
@@baxrok2. thanks!
hey man im about to go through with this swap. can you help me out the only part as of now that im not sure about is the intake manifold situation. how do i trick the ecu to use the 2.5 manifold and also where do you get the throttle body adapter? is that all i need?
You don't trick the ECU to do anything. Just use the 2.5 manifold and you won't have any problems. You will need the TB adapter or you can use a Speed 3 TB or a 2.5 TB I think. I used the adapter kit to use the 2.3 TB with the 2.5 manifold. You can get the TB adapter kit on ebay or you can go to Mazda3Forums.com and go to the engine swap threads to find the guy who makes them. It's been a while since I did my swap but I think that's all you'll need. Don't forget the cam timing wheel if you have an '04 or and '05. Again go to Mazda3Forums and go through the swap threads for details. Also, you can watch my How Much Did It Cost video to see what I used in my swap for some more ideas. Good luck!
@@baxrok2. ive watched every one of your vids on this topic man thankss by the way. so i dont have to do anything witht the vacuum acuators in order to not get a CEL. i may end up going with a 2.5 TB from a mazda
one guy on the forum was saying i need to make the purge valve a 2 port vacuum source but he diddnt say why. any idea on that??
i asked but havent responded yet.
also you said you have to mount a solenoid on the bottom of the 2.5 intake manifold is that just like a solenoid fromthe 2.3 thats not used on the 2.5 and you just have it plugged in to make the computeer happy?
If you keep the 2.3 mani all you need is the adapter to go between the mani and the 2.5 head. Beware of vacuum leaks! All of the connections are the same. If you keep the 2.5 mani, you need the TB adapter kit and you have to keep the IMRC solenoids and vacuum actuator connected. They will no longer be needed but need to be connected to avoid CELs. You can attach the vacuum actuator to the bottom of the mani using one of the available mounting posts as I point out in the video. The TB kit comes with (should come with) the needed vacuum ports on it as well as a new nipple for the purge valve. @@Samiam_ariel
Great video. Just a heads up, I think if you put the 2.3 cam in the 2.5, you have to grind down the #1 cam hold down a little.
I put a new Mazda 2.3 cam in my 2.5 and did not have to modify the hold down at all.
@@ratbert86 yeah I think mine may have had to do with being a hybrid engine
Would a 2010 Mazda 3 2.5 manual engine work
Yes, that is a much easier swap than the duratec engine because you can use the manifold and throttle body
@@pmac7527 thanks
Yes, manual or automatic, it does not matter. A Mazda engine swap is the easiest way to go. Otherwise, if you use the Fusion engine, you have to do a lot of part swapping.
Would you know what engines can go into the 05 mazda 3 2.3L?
Examples ford focus, ford fusion..
I put a 2011 Fusion engine in my 2005 3. For all of the details and choices you have go to HappyWrenching.com and look for the 2.3 engine swap article and blog. For more info, you can look through the info at Mazda3Forums.com. I put links to the good stuff in the description for you.
Was it difficult to hook up the wiring harness?
No, because you keep the original wiring harness. Everything plugs in just like the original 2.3!
Baxrok2 I don't have to change the computer?
No. Keep the 2.3 computer.
What tools/technique did you use to swap the cam timing ring? How did you reference the ring and cam? Great video btw!
It's actually pretty easy to do but very hard to explain! Use a regular gear puller to pull it off and a press or socket and hammer to get it back on. Go to this link and look for the picture of the two camshafts and timing cogs.
www.mazda3forums.com/61-powertrain-2004-2009-mazda3/647562-04-2-3l-swap-2-5l-successful.html#/
Line up the camshaft just like it is in the picture. Using the slot in the end of the camshafts as your guide, draw a horizontal line through the top edge of the slot and all the way out past the ends of the legs on the timing cog. Moving to the right side of the camshaft, you will see that the line will intersect almost perfectly with the bottom side tip of the timing cog leg that is opposite the slot. It's perfect for reference!
You'll see that this is true for both camshafts and timing cogs. Line those up and you're good to go. Hope this helps and if you do it let me know how it goes!
Thank you for the response. I just purchased a 2015 Fusion engine with 10K miles for $546 out the door from a Nashville junkyard. I'm putting it in a 2004 Mazda 3 hatchback that has a manual trans. I just tore down the 2.3 tonight and marked the timing cog per your instructions. Everything you said was right on.
I have a couple of other questions. I bought a adapter plate on Ebay for the intake to run the 2.3 manifold and keep it fairly stock. The intake is sludged up pretty badly and after watching your videos and reading the forum I believe I'm going to do the the Fusion intake and a Mazda 3 2.5 throttle body from Ebay.
Questions:
-Where did you get the adapter for the purge valve hose connection? It looks like you deleted the purge valve and have a adapter there.
-Also, where would I tie in the vacuum solenoids for the old intake runner control? It looks like you tied into a T/B adapter. Where did you get that? I read about a guy using the 2.5 T/B making a vacuum manifold and tying it in with the purge valve port. Does that sound doable.
-How did you tie in the brake booster hose?
-Any suggestions on the brand/type of clutch kit to install?
I know those are a lot of questions. Don't mean to monopolize your time. Thank you in advance.You are a wealth of knowledge. Your timing how to is great.
Yeah, I'd keep the 2.5 intake and get the 2.5 TB. Skip the intake adapter.
The purge valve setup and the tie ins for the runners came with the TB adapter kit that I bought. I purchased the TB adapter kit since I hadn't really thought things through at the time. I should have bought the 2.5 TB. My swap is now a year old and honestly I'm not remembering the routing of all the lines. Sorry. I do think that you could fabricate a manifold of some sort to create a vacuum source. I'll have to look at my brake booster line to see what exactly I did with it but I don't recall doing anything special with it. If I can I'll look tomorrow. If you watch my Problems, Problems video you may be able to see all of the routing and connections at the TB.
I bought my clutch off of RockAuto. I bought the Exedy (Daily Driver grade) clutch kit. $154. MZK1003. I'm happy with it. Pedal pressure is medium to light and seems a lot lighter than the stock pedal pressure. Hope this helps.
Did you notice a discrepancy in the oil level between the two dipstick locations? I left the spin on filter on the Fusion engine and blocked the oil pan dipstick hole to eliminate it on the 2.3 pan. After the install I added 4.5 quarts of synthetic oil and ran the engine. It now reads 1/4 quart over on the fusion dipstick. I was wondering if you found a difference in the two sticks as you were originally running both.
I did finish the swap btw and used some of your suggestions. I swapped the cam gear according to your direction and also timed the engine using your videos for reference. I'm running the Fusion intake, valve cover, VVT solenoid, oil filter setup and '09 Mazda 6 2.5 T/B. Had to swap the VVT connector from the Fusion harness which I got with the engine thankfully. Running a M-Pac stage 1 clutch.
Rickkari7 Congratulations and nice job! No, I didn't notice any discrepancy between the two sticks.
Can I swap a 2017 2.5L Inside a Mazda 6 2.3?
For a first gen Mazda 6, I believe that you have to stick with something before 2011.
@@baxrok2. okay I have 2008
@@baxrok2. So would I have to get a 2011 2.5 to swap with my 08 2.3?
@@ohiojayohio9643 As far as I know, yes. However, I've never worked on a 6 and they are different from the 3's. This guy did a pretty good write up on the swap and has some good information that might help you. www.happywrenching.com/mazda/6/mazda-6-and-ford-fusion-23l-engine-swap.html
@@baxrok2.Thanks a lot I'm gonna follow the guide you sent me. My man Thanks!
Quick question on the 2.5 motor which side is the alternator on? Exhaust or intake side?
Intake. You can see it on the left side where the drive belt runs.
I am doing this swap do I use 2.5 spark plugs or 2.3 ?
If you're using the 2.5 coils then use the 2.5 plugs.
It appears that you did this video about 3 years. You don't by chance recall about how long it took, do you?
In one of my other videos I talk about the time factor. A straight Mazda 2.3 to Mazda 2.3 swap can IMO be done in a weekend. The Fusion 2.3 swap was much more involved, not to mention how I work (alone/slow/methodical), how often I worked on it (after work/weekends), the fact that it was my first swap (learning as I went), and all the bumps (parts needed, etc,) along the way. Unfortunately, this time frame also included almost three weeks of diagnostics (turned out to be that the timing was set wrong by someone I paid set it.) Total time was almost a month. Without the timing snafu it probably could have been done in half the time.
Hey I need one of those 2.3l engines. Got any?
Nope. Sorry.
Hi, thank you for the great and detailed video! I was wondering if you could possibly help and/or point me in the right direction. I have a 2005 hatchback and wanted to look into putting a 2006 2.3L engine. I know the intake cam is different, but wondering what options I have. Thanks!
I don't know what other options you have other than options on how to deal with the different cam wheel. Some folks just use the 2005 cam on the 2006 engine and others, like me, just swap the 2005 cam wheel over onto the 2006 cam. Not many folks I know would be willing to put a worn cam into a newer engine, however if the engines are both of a similar age, mileage, and overall condition that may not be such a big deal. I put a 2011 engine with 58kmi into my car so no way I was using the old 2005 cam! For more info go to Mazda3Forums.com. If it can be done then these guys have done it!
@@baxrok2. thank you! Can the timing wheel be replaced without removing cam or messing with the timing stuff? I really don't want to go down that rabbit hole, if possible.
goZander this is the mistake I made after completing my swap. Car would crank but won’t start. A more informed DIYer questioned me on things I switched over, not realizing I should have done something with the camshaft, then figured out the timing wheels were different. Can’t believe I made it this far only to discover a (what I consider) major mistake. Now I’m trying to figure out how to correct it. Hoping Baxrok2 may have some insight to help guide me.
It sounds your son is going to have a nice car when your done. Learning is why we share and I'm sure this will help someone. I'm like you, a DIY'er who's been working on stuff since 14 but learning all the time. Especially in the world of diagnostics. Send me your address if you like because I'd like to send you one of my stickers. Merry Christmas.
Well, if I can't figure out why it won't run, he may be getting a different car after all! This is when I need the wizards at PHAD and SMA!
No doubt. Those guys make it look easy. I'm fussing with this 1998 Chevy that won't start when it's cold outside. Right now it seems to be okay, but I don't trust the fix.
That's the rub right, confirming the fix. Experience matters and those guys have it! I actually wrote to Ivan to see if he would contract with me to work remotely. He could suggest direction and I'd do the work. No response from him so, I'm guessing that's a no. lol Oh well, I'm pressing on. Merry Christmas!
That's too bad he didn't respond. I know those guys stay busy though. Have a great 2017 and maybe we'll see you at the next meet up.
Thank you for the educational video. You have my respect.
Did you leave the transmission in the car?
No, the transmission came out as well since I was putting a clutch in too.
Baxrok2 What clutch did you put in? I just got an Exedy Stage 1 in the mail a few days ago.
@@MrHevelifter I got the same thing from Rock Auto. Light pedal pressure compared to the old one which was the original and very stiff.
ok, i note that you said it wont be easy or as straight forward. But in my case i just want to swap the same engine from my old mazda to my new one. They are both 2.3L so would the process be as difficult or maybe less challenging?
Eduardo Duran Less challenging for sure! If you watch my video, I say clearly that a Mazda to Mazda swap can easily be done in a weekend. Good luck and let me know how it goes!
I am peering into the rabbit hole right now?? I have a few specific questions about 2.3l can I e mail you?? Cheers!! Great video!!
Sure, I'll help if I can.
can you e mail me @ andy.holtzman@gmail.com ?? will get into more details. I'm hoping your answers can save me a little money. lol Thanks Andy
Will 2.5 injectors fit in 2.3
Yes.
Baxrok2 will it send more fuel with out me messing with the computer
Wait a minute, you asked if the 2.5's will fit in the 2.3. I misread that. I can't say for sure since I only tried to put the 2.3's in the 2.5 and they fit. The 2.5's should fit in the 2.3 but you may have to play around with the fuel rail to get it right. Sorry, bout that.
Most people, myself included, feel that the 2.3 PCM can easily handle the 2.5 injectors. Of course, there are many factors in play so you'll basically have to experiment to be sure. I ran the 2.3 injectors in the 2.5 without a single problem so can't see why it wouldn't work the other way around.
Baxrok2 OK thanks
Hi sir, quick question, where is the knock sensor located? Is it under the intake manifold?
Yes. Under the intake. Google Mazda 3 knock sensor and go to images, you'll see pictures of it.
Baxrok2 follow up question, is the 2.5 mazda intake interchangeable with 2.5 fords? Thanks.
bhadz100 I can tell you it boils down to the physical size of the passages. Putting in a 2.5 Mazda engine in place of my Mazda 2.3, the intake passages for the 2.5 are bigger so I bought an aluminum adapter with a gasket on eBay to avoid air leaks.
Thank you, talked me out of it. Dont have that much time to mess with it
It's only really worth the time if you've got another cheap Mazda engine which hopefully isn't also worn out! Mazda to Mazda is a weekend job!
I'll pay someone for the labor
@@badjujukarma That still does not mean that it will be done right which can be very frustrating to deal with after spending all that money.
Exelente información gracias
The 2.3 liter has 135 Hp & 153 Lbs torque.
The 2.5 liter has only 119 Hp & only 146 pounds of torque! Why would you want to switch a more powerful & more fuel efficient engine for a less powerful and less fuel-efficient engine?!!
Because when your garbage 2005 2.3 fails, a 2011 2.5 is easy to get, cheap to buy, and way more reliable! lol Why wouldn't you want to! I think your HP numbers are wrong btw.
Oh crap oh I was looking for the cars online they are nice looking for the years affordable not expensive like corolla
Yes, but you have to be careful that you're not getting one that burns a lot of oil which eventually can lead to rod knock and engine replacement.
This engine can swap into rx8??? How hard its goona be ??? And cost?
Victor Gomez Sorry, I don't know anything about RX8. You surely wouldn't put a 2.3 in place of the rotary!
mazda 3 is a beautiful starter car !
Engine my car Mazda 3 2.3 I want to make it 2.5 what I do
wow. that's a lot of info!
Mazda 3 similar to Mazda 5
If it has a 2.3 or 2.5 engine.
I. Want to switch mine for a manual engine but don't know if it's worth it
@@badjujukarma Probably easier and better in the end to just by a manual. That way everything is right and less problems and money.
Yes true that
44 minute video with only 10 minutes of relevant content.
Well, yeah. I even titled it Blah, Blah, Blah as a warning. lol Surely you didn't think I'd make a video with only the 10 minutes of content that was relevant to you!!
O
Ehh, i rather just keep my regular 2.3l in my 2006 Mazda 3. The 7 HP extra horsepower from the 2.5L doesn't seem worth the time and headaches in doing this swap.
I agree, for the horsepower alone, it's a total waste of time and money.
It has more like 8 hp less!!
