This video was posted 7 years ago and you probably won’t see this comment but I just have to say I’ve been watching your engine build videos over the years and they were always top notch but I had no idea the absolute amazing fabrication skills you possessed! Freaking excellent job man I’m blown away I’m going to watch this video a few more times over the weekend. I am super impressed!
As a mechanic in Australia, I only ever saw the insides of a rotary at trade school. Your videos were great for me to watch as it clearly demystified the rotary for me. I built many high horsepower engines only now to see that had I taken the plunge into rotaries I could have done it easily. Just my workshop with ridge removers, cylinder hones, conrod alignment and balancing, valve facing machine, boring bar etc etc - all totally redundant. Thanks for posting these videos.
Great build, and what a choice for a sleeper! Most people would be leary of racing any rotary vehicle, but the 79-80's with their steel bumpers, plaid interior and especially THAT paint!.....gonna surprise many who would challenge it!! Also a great choice to spec the chassis with the highend SE running gear. Its too bad the wonky position of the 79-80 shifter caused so much trouble with engine placement. That's where I'm glad I have an 84, since the interior console is pushed back a bit. It made fitting up my S5 TII quite a bit easier. Even with the stock OMP and my aftermarket rack and pinion steering, any 13B swap is a cakewalk compared to the 20B. FWIW, I have over 15 years of daily driving on my 350hp-ish S5 swap, running into the stock SE rearend....its a pretty tough little nut. Congrats on a clean, tasteful and massively overbuilt sleeper!
20 years after my friends were putting these into their 70's carolla's, and crx's, i still havent driven one but they sure do make me smile when everyone underestimates them.
i started watchig this tiered af and fell asleep at about 50:00 somthin... to BE AWAKEN BY THE LOUDEST EVER ROTARY ON THE PLANET, i allmost had a heart attack lol... never have i reached my pc from the couch so fast to turn the sound off even if the wierless mouse was right next to me....
Except for the fact that the more cash you earn the higher taxes you pay just to make sure you aren't getting what you deserve after all that hard work.
Beautiful work, craftsmanship, manufacturing, fabrication..I cant express how awesome this video was, and how much information there is to absorb..Thanks REC A M A Z I N G
My profession is completely different. However, when it comes to custom work and the satisfaction of making things fit and work together just right, I definitely know that feeling.
I built a lot of engines in my early years as a mechanic and I can tell you guys know yer SH**, I mean "stuff". Plus you take great pride in doing a methodical and precise build paying close attention to detail. I don't know what the price is for one of these but I'm sure it's fair considering the research and testing you've obviously done.
Some of those oil pan welds looked sloppy...Not sure on the details of HOW it was assembled, but those welds looked like shit I did in high school.... I'll just assume you touched up the holes and globbyness before you painted it, or your gunna get massive seam rust down there.....Everything else was spot on (bent radiator fins is no biggie and happens all the gawd damn time on those old rads).
PLEASE do more videos JUST Like this one, 1.Building the Performance Motor with upgrades, 2. Putting the motor in the car, 3.Give a run down of everything, 4.START !!!! These videos are freaking awesome!!! AND your good at walking through with what your doing man! My hats off to you my friend!!! I'm probably going to be hitting you guys up for some buisness.... As I'm in the market for some FDs or FCs. Hands down... Awesome Videos dude!!
Awesome video. I have been building piston engines for over 25 years. Never been into a rotary. Really nice to see one apart and explained. Really a simply elegant design. Awesome fab work on the X members and oil pan and trans + everything else. Top notch. I worked in NASCAR for almost a decade and I know good fab from bad and you guys are super. Thanks. Gonna be one hell of a sleeper. I love building sleepers.
FANTASTIC idea to video a customers build!!! that prooves your work and that you have nothing to hide, i would feel ensured not to receive a sloppy work nor that you cut corners. that builds trust and it makes me want to send my chevy 350 to your shop... = )
I love your dedication and expert knowledge and innovation. I would love an RX7, and to live near you to work your magic to it ! Many thanks for taking the time to make this wonderful and absorbing film !
This is an updated version of the video we uploaded a couple days ago. Our apologies for the comments that had to be removed with that version of the video.
Your video's are awesome and I have learned a ton about rotary tech from all the great info you have put out. I would love to see some videos about the pros and cons of different parts recipes and # of rotors. Also would love to see a break down of any care and feeding of your rotary type info you might like to pass on, I would be interested specifically in engine life spans and oils/coatings you might want to talk about. Just some ideas I hope you keep making videos you are training new engine builders and that is a noble thing. Thank You! and Merry Christmas
Great suggestions and we have agreed to do this in the near future. Once we get the big projects posted on RUclips and the customer requested videos taken care of as we go, we will aim to go more in that direction. Stay tuned!

beautiful work and build.but why not a better throttle body.and what ecu are you using.the 20b is so long it tends to flex .i think all the 12.7mm studs go straight through will help alot.the 20b always damage the centre bearing ,even with after market bearings.what apex seals are you using.thanks keep up the great work.
The oil pan mod looks great and sure enough will work out ! If you look back in the early 90's ford motor company did exactly the same oil pan mod to their 5.0L v8 to fit it into those early year mustangs , like the very first Mustang "R" in '92.
Very thorough step through. One of the problems with rotaries is that a significant component the force produced from the combustion process contributes to the rotor’s sporadic angular momentum at only acute/other angles; rather than - as a traditional 4 stroke/piston engine does - contributing a significant component of the force produced from the combustion process in the same direction as the downward travelling piston. That said, their absence of reciprocating mass and a valvetrain - combined with the addition of port geometries that even rotary valve piston engines would be proud of, certainly go a long way to compensating for that. I knew a guy years ago that had a 428 cobra-jet Mustang running high compression, dual dominators, nitrous and a few other modifications that made his car the fastest in the hood. That was until he accepted a challenge from an old beat up looking Mazda with undercoat splotches all over it. I had been in the Mustang a few times and it was certainly extremely powerful and fast; it could easily lay rubber as you changed into 3rd with 4 people in the car. Back then not much was known about the potential of rotary engines, and most tradition hot rodders laughed at them. The Mustang owner was completely oblivious of them, and also how modified the Mazda was also. After the Mazda won the ¼ mile race the Mustang owner was so embarrassed that he sold his car. Prior to that the Mustang owner had owned it for 8 years.
The Doritos sound incredible. I hope it got the exhaust system it deserved. Catless, no mufflers, large tips. God, even those turbos sound great when you rev it. Great job, 1 year later.
Glad you liked it but just so you know the piping and muffler were both temporary and were not delivering the sound that it should have. At that point there was also no tune in the ECU (very basic base MAP) so the engine only sounds good cuz 20B's just sound that good period. The custom turbo system we built is as good as they get and no doubt it will eventually deliver on all aspects when finished. My personal car (20B/FD) has a very similar turbo / manifold set up coupled with a rare 3 1/2 V-band exhaust with straight through resonator and free flow cat back. I will feature my car in an upcoming video...then you'll hear the true roar of a 20B
Anything engine and drive line related but we dont get heavy into putting in custom rear ends and suspension from other chassis nor do we do any body work
beautiful rotary motor brother keep up awsome work im a lt1 muscle guy but got respect small rotarys people be sleepin with these rotarys boy,,,,, the horse power they make wooohoooo turbo crazy keeep up good work made props to u brother
si bland I'm not RX7 Specialties but in either twin / single turbo setups, the air filters are on the turbo(s) so any air entering the intercooler will be filtered.
I have to say, while I admire the work you guys did here, as someone who just stumped over this video I'm really surprised someone would spend that amount of effort/money on something that seems like a old-junk-car to me.
I absolutely 100% enjoyed watching every moment of your video! You are expert builders and it shows. My brothers had 12A and 13B rotary powered RX7's. I was fortunate enough they let me drive them. I've always been enamored by the profoundly elegant minimalism of the wonderful Wankel engine design. I think it's terrific that there are folks running these engines in cars they will come to cherish and rightly be proud to own. Kudos to you gents for having the automotive skill, talent and professionalism to support that market!
Sounds like god's hot rod leafblower! Incredible engineering and fabrications skills too. I love that the car this build went into is clean but far from perfect--even sleepier that way. Hope to have you build something exotic for me someday.
great vid and great work, thanks. love the whole concept the owner is going for, but can someone convince him to put some brakes on it to match the power?
We got into the practice, back in the 70's and 80's in V8 performance engines, to build the bottom end to withstand 1,000 rpm more that what it should see at redline. I've only had one engine break, and that was due to the addition of NoS that wasn't accounted for during the build. We had no other failures other than when the customer chose to finish assembling the longblock themselves. Most often this would be a small block Chevy where they re-used the original oil pump pickup tube and then used too much RTV on the oil pan, allowing a pinched off bead of RTV to get sucked past the screen on the pickup tube and seize the oil pump. Chevy screens detach from the inside of the pick tube's can when too much sludge builds up to prevent oil starvation, and then when they use it during the rebuild it gets sucked right into the pump. The other cause is dirt getting into the engine, destroying the bearings.
Always love seeing shops use schedule 40 tubing for exhaust manifolds. Cant tell you the number of times I had rx7's come into the old shop where I worked and complain about some e-bay special manifold that cracked/broke............. Though I'm not a fan of lapping irons. In my experience the nitrating depth is inconsistent. I've lapped and the motor was fine after considerable miles, however I've lapped and the engine went to pot in 4k miles. Just the one iron that I lapped........... (of course I ate the rebuild)
The first one I thought I must have done something wrong, because it was just the 1 iron. The side seals just dug right into the iron, scored up the surface..........Well you know how that goes. Fortunately the customer brought it back quickly as soon as it started hard starting a little bit. When I seen the rear housing was lower on comp. (if memory serves +-20-25% lower) than the front housing I knew something mechanically was up. But what confused me at the time was it was all 3 faces. Anyhow got it apart and that's what I found. The rear iron was all scored up from the side seals. And that one was lapped. After I rechecked my build log, I chalked it up to maybe a side seal/s were harder than they were supposed to be. Other than the rear it was beautiful. Actually I was quite pleased otherwise. It was my first time getting to see a NRS 3mm 1pc seal working with JHB housings. (well first time getting to check one out with significant miles and abuse on the combo) Some time down the road from that one (couple of years if I remember right) I had it happen again. Same exact symptom. But this time it was the rear face of the intermediate iron. After that we stopped doing it. More as a precautionary measure, "just encase" to eliminate a variable. Some time later I heard Pineapple ran into the same issue. Though I heard that 2nd,3rd or 4th hand so I don't know that to be true.
Awesome build and very informative video great work love how you explain things I’ve been building engines for several years race and street but I’ve never laid hands on a rotary engine but they really are fascinating to me !!!!!!
Nice work lads, it sounds like a 3 cylinder version of my CR 500 minus the Turbo of course. That was a Mega difficult job, though I would recommend a heat shield on that Turbo before it melts something. Would like to see it performing up the road. Oh and the sleeper bit I think is blown with that noise going on. I had a real Sleeper, as quiet as it was standard and even very nearly sounded the same too but if you ever open the throttle past half way people knew then it wasn't standard by the sudden Growl coming from the motor and the carby Snorting sound it made apart from the fact the front end lifted a lot & the car took off, but nothing like 700 HP on this build, but the difference between my rig and this one is I had tail shaft Twisting power at 1200 revs..
Very nice attention to detail. You make a real fine engine and I'd have you build one for me any day!! I would like to see it perform on the street or strip!
Comment: 1. Why is idling lumpy since the primary ports are only street ported? 2. Turbo inlet is taking in hot air from behind the radiator? Otherwise, top notch engine assembly...thanks.
Have to say that from get go , your build looks like " THE BUSINESS ". Build looks exactly similar to Legendary Mazda 767 C group racing engine build. Tho i think they used titanium on some studs/strengtening bolts. But other than that, it looks absolute joy to see people doing things right the first time and not skipping anything for money or time saving. 10/10
Great job, but was it really necessary to put that type of fuel delivery with the pump in the cabin? Do you have to listen to the tack-tack-tack-tack-tack all the time you are sitting in the car?
In may 1988 I took a job selling Mazda's Porshe and Audi. I was young never sold cars but was a prove closer. I was told import buyers are different you needed to know the product for my first 2 weeks I was instructed to study all the models and drive them. There was a spot one could go to put your foot down without worry on Dow Chemical property. So I got around to the 89 Turbo II that was it .. guess what car was the first one I sold ;) yep a turbo II guy came in to buy a 911 when I price qualified him I told him for his money the RX7 was just as fun as the 944s4 , our 911 was a dog and his buget was realy 924 money but I said you can get for a little more a R7 Turbo II a drive out to my spot he couldn't pull 5K out of his pocket fast enough to make his offer. I got $2k over sticker ;) I didn't even know how to do the paper and wasn't supposed to even take-ups shit happens. I would still take the 944 s4 but for the money ;)
I've been scouring the internet learning about rotary engines as much as I can before buying an rx7. My question is why bridge port the intake ports and street port the exhaust ports? Would love to know!
We dont....Did I miss something or did you see a bottle of thread lock near the assembly area and mistook it for an actual applied product? The only thing that foes on the side housings and corner seals is assembly lube?
Ohhh that JOSH. Ok well if I had drawn the association of your name with our friendship I would have totally caught the wise guy humor. I guess Ill have to see your posts in true light from now on. HaHa. Talk soon Josh
Hey Adam, nice build! I enjoyed watching your work on the classic 79 RX7. Had a couple suggestions on the videography. The fade in and out on the stills was a bit much especially as fast as you cut from scene to scene and the written description didn't last long enough for me to read it, so had to back up and pause, which is no big deal, just interrupts the flow. Otherwise, excellent work. You guys did a bang up job on the custom fab work. I know how much effort we put into building the Turbo RX8 project car with all the custom fab work. I agree with the other comment about the air filter sucking hot air off the heat exchangers needs to be corrected. I don't know why anybody would spend so much money on a build like that (or any build for that matter) and not want to protect the engine and maximize performance as much as possible by avoiding inhaling hot air. I guess he won't really be able to use even half the power its capable of with stock 14" wheels, so hot intake air probably won't make a difference in his application. Gonna melt the rubber right off the rims if he nails it thought. LOL..
Hey Richard hows it goin? you know what funny...when my editor was done with it and I finally watched the entire thing....I picked out the exact same things. I mean exactly those 2 points caught my attention and thus mentioned to him. We agreed it was a bit too late to change it now...especially since we had already taken it down once and reposted. If it wasnt for that repost already I actually would have leaned toward re-doing it. FYI all the vids we have done so far are rushed using from unfinished B-roll. I have never put in full effort due to time. We have the capability to do this with very high end equipment so from my view...nothing I've done so far it what I see as top professional work. Its a balance of time ..as Im sure you can understand. Love the advice...keep it coming!
The oil pan had 3 deeper areas (chambers). Won't the oil just sit in 2 of those deeper areas (except the oil pickup) until the oil level is so that it spills over to the oil pickup chamber? Is the oil level sensor in the pickup chamber, if not then it's quite pointless to have the sensor as it always reads full. NB! Much respect for the assembly and being able to fit this monster under the hood!
OK so these guys are the experts- but I didn't see any lubrication on the rotor bearings, are they really supposed to be assembled dry or was that step not shown?
That is a amazing job u guys did I've seen theses motors but this is by far nice build sounds nice as well and a lot of time went into this motor for shore ...👍🏼👍🏼👍🏼
Great video. I bought a rebuild kit from you guys a few months ago and was very pleased. Price was great and shipping was fast. Out of curiosity, what are your costs to lighten, clearance, and balance a 13B REW rotating assembly (looking for a 9000-9500rpm redline). Just wondering for a future project.
loss interest in listening to this before they flipped the case because the build was not about "assemble" but about the "dowel" work this shop does. Nothing about the work he was doing to actual build the motor.
How the hell has the RUclips algorithm never delivered me this video in 6 freaking years??? Rotary? YES. Sleeper? YES. 700HP rotary sleeper? HELL YES.

That's a hilarious analogy. In survival mode we tend to go for the lower tech solution. Primal?
First four minutes just loved talking to himself.
that sounds like the first thing I'd buy if I win the lottery!
caramelbear757 that's exactly what I was thinking!! lol
hard work pays off man

Except for the fact that the more cash you earn the higher taxes you pay just to make sure you aren't getting what you deserve after all that hard work.
I agree.. Legalized extortion
First minute, the background, rotors, engine blocks, it's like rotary heaven.
Beautiful work, craftsmanship, manufacturing, fabrication..I cant express how awesome this video was, and how much information there is to absorb..Thanks REC
A M A Z I N G
You're very welcome...our pleasure!!
Amazing craftsmanship. The owner must have had very deep pockets to finance this work. Well done.
@@msattler111 4 Sure! $$$
I love these videos. Makes me confident that when I do have the money for a build, this is the guy I want to use.
Would be my pleasure
RX7 Specialties man y'all know how to build a rotary. ya might have to build me a custom made 3 rotor turbocharged to swap into my Acura Integra
Yea but... use your hands = more pleasure
DEEREMEYER1 personally myself im saving for a trip to japan and putting aside 5k for an trashed fd rx7 and bringing it back to Canada with me
My profession is completely different. However, when it comes to custom work and the satisfaction of making things fit and work together just right, I definitely know that feeling.
You guys did a amazing job,I love how you worked with the owner to keep the cars originality in tact with very little performance penalty.
I have almost 0 clue about any type of combustion engines and yet I like the building and explanation of it, thank you.
I built a lot of engines in my early years as a mechanic and I can tell you guys know yer SH**, I mean "stuff". Plus you take great pride in doing a methodical and precise build paying close attention to detail.

your exhaust manifold and turbo assembly is absolutely amazing. what a feat of engineering.
Motor went together like butter. That's a tight build, literally.
Shane Bigler literally? Well you didn't mean metaphorically did you? -_-
Thank you
Don't know why but I found this video extremely relaxing and calming to watch..
All hail Dorito engine power

RX7 Specialties hello is there an email i can reach you at? Or a number. Please and thank you.
One of my goals eventually is to put a 20b in my 1st gen. Thank you for the full build video!
That sounds about as stealth as the Saturn V rocket lifting off!
You know you really love rotary engines , when you have a rotor tattooed onto your arm lol
Wind of cha
Earned a sub for it lol. Thats dedication
For life!
Or Doritos :)
Awesome video man rotary engines so much less complicated than conventional internal combustion engines
The oil pan mod looks great and sure enough will work out ! If you look back in the early 90's ford motor company did exactly the same oil pan mod to their 5.0L v8 to fit it into those early year mustangs , like the very first Mustang "R" in '92.

I knew a guy years ago that had a 428 cobra-jet Mustang running high compression, dual dominators, nitrous and a few other modifications that made his car the fastest in the hood. That was until he accepted a challenge from an old beat up looking
Mazda with undercoat splotches all over it.
I had been in the Mustang a few times and it was certainly extremely powerful and fast; it could easily lay rubber as you changed into 3rd with 4 people in the car.
Back then not much was known about the potential of rotary engines, and most tradition hot rodders laughed at them.
The Mustang owner was completely oblivious of them, and also how modified the Mazda was also.
After the Mazda won the ¼ mile race the Mustang owner was so embarrassed that he sold his car.
Prior to that the Mustang owner had owned it for 8 years.
There's almost no way to turn a 3 rotor into a "sleeper".
Maybe when it's parked....
If it had a street port and a quiet exhaust, absolutely sleeper. This combo is too rowdy....but wow! Excellent job!
haha, right? more like the neighborhood menace
The Doritos sound incredible. I hope it got the exhaust system it deserved. Catless, no mufflers, large tips. God, even those turbos sound great when you rev it. Great job, 1 year later.

What a sleeper this car turned out to be. Congrats!!!!
You guys are the bomb! That is awesome how much fabrication and custom work you do. Very impressive!
Anything engine and drive line related but we dont get heavy into putting in custom rear ends and suspension from other chassis nor do we do any body work
beautiful rotary motor brother keep up awsome work im a lt1 muscle guy but got respect small rotarys people be sleepin with these rotarys boy,,,,, the horse power they make wooohoooo turbo crazy keeep up good work made props to u brother
Thanks!
I love the Bridgeport sound, great project
You guys are awesome! My REC engine runs like a beast.
20b with stock fb suspension, whoever paid for this build is a true madman
Haha!
Excellent video. That engine sounds awesome.
Thanks for watching..glad you enjoyed it
RX7 Specialties is it wise to have a air filter near the rads where hot air blasts at it .
si bland I'm not RX7 Specialties but in either twin / single turbo setups, the air filters are on the turbo(s) so any air entering the intercooler will be filtered.
No not at all but tight for space. Owner might build some sort of cold air duct soon
RX7 Specialties where is your shop located
Incredible!. My favorite body style I miss mine.
Love that swap
I have to say, while I admire the work you guys did here, as someone who just stumped over this video I'm really surprised someone would spend that amount of effort/money on something that seems like a old-junk-car to me.
Customers wishes.
Magnificent attention to detail and accuracy!
Sleeper that lopes like a top fuel dragster and revs like a chainsaw. I think they're gonna know something is up captain.
The background at the start, my god. So pretty.
Now this is the real rotary engine lookup..all the points are here..
I absolutely 100% enjoyed watching every moment of your video! You are expert builders and it shows. My brothers had 12A and 13B rotary powered RX7's. I was fortunate enough they let me drive them. I've always been enamored by the profoundly elegant minimalism of the wonderful Wankel engine design. I think it's terrific that there are folks running these engines in cars they will come to cherish and rightly be proud to own. Kudos to you gents for having the automotive skill, talent and professionalism to support that market!
Thanks for the kind words. Glad you enjoy watching!
They really built a very impressive piece of art, thank you for sharing
your welcome
Sounds like god's hot rod leafblower! Incredible engineering and fabrications skills too. I love that the car this build went into is clean but far from perfect--even sleepier that way. Hope to have you build something exotic for me someday.
Look forward to helping you
Just came across your channel the fact that you video document the build at request is awesome when I got mine done I would have loved them to do this
Whenever you're ready we'll be here!
great vid and great work, thanks. love the whole concept the owner is going for, but can someone convince him to put some brakes on it to match the power?
HAHA My thoughts too....sleeper with factory options was the request...so...
WOWOWOW, never knew these type of engines sound so good
We got into the practice, back in the 70's and 80's in V8 performance engines, to build the bottom end to withstand 1,000 rpm more that what it should see at redline. I've only had one engine break, and that was due to the addition of NoS that wasn't accounted for during the build. We had no other failures other than when the customer chose to finish assembling the longblock themselves. Most often this would be a small block Chevy where they re-used the original oil pump pickup tube and then used too much RTV on the oil pan, allowing a pinched off bead of RTV to get sucked past the screen on the pickup tube and seize the oil pump. Chevy screens detach from the inside of the pick tube's can when too much sludge builds up to prevent oil starvation, and then when they use it during the rebuild it gets sucked right into the pump. The other cause is dirt getting into the engine, destroying the bearings.
Beautiful craftsmanship. Kudos.
Thanks a lot!
Your shop does good meticulous work. Great job.
Appreciate that thank you
Always love seeing shops use schedule 40 tubing for exhaust manifolds. Cant tell you the number of times I had rx7's come into the old shop where I worked and complain about some e-bay special manifold that cracked/broke............. Though I'm not a fan of lapping irons. In my experience the nitrating depth is inconsistent. I've lapped and the motor was fine after considerable miles, however I've lapped and the engine went to pot in 4k miles. Just the one iron that I lapped........... (of course I ate the rebuild)
Interesting...been lapping for 20 yrs and never had one issue
The first one I thought I must have done something wrong, because it was just the 1 iron. The side seals just dug right into the iron, scored up the surface..........Well you know how that goes. Fortunately the customer brought it back quickly as soon as it started hard starting a little bit. When I seen the rear housing was lower on comp. (if memory serves +-20-25% lower) than the front housing I knew something mechanically was up. But what confused me at the time was it was all 3 faces. Anyhow got it apart and that's what I found. The rear iron was all scored up from the side seals. And that one was lapped. After I rechecked my build log, I chalked it up to maybe a side seal/s were harder than they were supposed to be. Other than the rear it was beautiful. Actually I was quite pleased otherwise. It was my first time getting to see a NRS 3mm 1pc seal working with JHB housings. (well first time getting to check one out with significant miles and abuse on the combo) Some time down the road from that one (couple of years if I remember right) I had it happen again. Same exact symptom. But this time it was the rear face of the intermediate iron. After that we stopped doing it. More as a precautionary measure, "just encase" to eliminate a variable. Some time later I heard Pineapple ran into the same issue. Though I heard that 2nd,3rd or 4th hand so I don't know that to be true.
very nice build,now I know we're to go for my 85 gsle drag build, very nice build,thank you for sharing
Your welcome and look forward to helping you out someday
Wow great work! All the custom work to keep it a sleeper like the oil pan is especially good.
Awesome build and very informative video great work love how you explain things I’ve been building engines for several years race and street but I’ve never laid hands on a rotary engine but they really are fascinating to me !!!!!!
Glad you enjoyed it!
Great video!! Love the sound and love the idle!!
Nice work lads, it sounds like a 3 cylinder version of my CR 500 minus the Turbo of course. That was a Mega difficult job, though I would recommend a heat shield on that Turbo before it melts something. Would like to see it performing up the road. Oh and the sleeper bit I think is blown with that noise going on. I had a real Sleeper, as quiet as it was standard and even very nearly sounded the same too but if you ever open the throttle past half way people knew then it wasn't standard by the sudden Growl coming from the motor and the carby Snorting sound it made apart from the fact the front end lifted a lot & the car took off, but nothing like 700 HP on this build, but the difference between my rig and this one is I had tail shaft Twisting power at 1200 revs..

I just finished watching this. very very very! inspiring.
Glad you enjoyed
Very nice attention to detail. You make a real fine engine and I'd have you build one for me any day!! I would like to see it perform on the street or strip!
Thank you
Comment:
1. Why is idling lumpy since the primary ports are only street ported?
2. Turbo inlet is taking in hot air from behind the radiator?
Otherwise, top notch engine assembly...thanks.
Gotta love the sound of a hopped up rotary when it idling.
Would love to see more build videos like this
Perfect job guys 700hp nice sleeper two thumbs 👍up
Beautiful work and build !!
Fantastic Build Walkthrough! Thanks to you guys and the Owner :-))
Have to say that from get go , your build looks like " THE BUSINESS ". Build looks exactly similar to Legendary Mazda 767 C group racing engine build. Tho i think they used titanium on some studs/strengtening bolts. But other than that, it looks absolute joy to see people doing things right the first time and not skipping anything for money or time saving. 10/10
Glad you can appreciate good quality
Wow, Pure artwork. Thank you.
This thing is not an engine. It is a motor.
What a sick build
The best thing is nobody will ever know it’s a sleeper!
Not a big RX7 fan as the anemic stock 1st gen is all I've ever driven... But this looks incredible!
It purrrrrrsssss that sounds so nice great job job keep up the good work
Nice build. I just hope no serious oil starvation with the oil pan modification.
The rotary engine is awesome!
Great job, but was it really necessary to put that type of fuel delivery with the pump in the cabin? Do you have to listen to the tack-tack-tack-tack-tack all the time you are sitting in the car?
In may 1988 I took a job selling Mazda's Porshe and Audi. I was young never sold cars but was a prove closer. I was told import buyers are different you needed to know the product for my first 2 weeks I was instructed to study all the models and drive them. There was a spot one could go to put your foot down without worry on Dow Chemical property. So I got around to the 89 Turbo II that was it .. guess what car was the first one I sold ;) yep a turbo II guy came in to buy a 911 when I price qualified him I told him for his money the RX7 was just as fun as the 944s4 , our 911 was a dog and his buget was realy 924 money but I said you can get for a little more a R7 Turbo II a drive out to my spot he couldn't pull 5K out of his pocket fast enough to make his offer. I got $2k over sticker ;) I didn't even know how to do the paper and wasn't supposed to even take-ups shit happens. I would still take the 944 s4 but for the money ;)
Fantastic Video! Thanks for sharing all of the information. Thumbs up!
You are so welcome. More on the way
I swear this man can talk about his fucking dowel pins and studs for hours
I've been scouring the internet learning about rotary engines as much as I can before buying an rx7. My question is why bridge port the intake ports and street port the exhaust ports? Would love to know!
good idea using permatex 609 thread lock on the side housings and corner seals to keep everything in place during the build.
We dont....Did I miss something or did you see a bottle of thread lock near the assembly area and mistook it for an actual applied product? The only thing that foes on the side housings and corner seals is assembly lube?
im just being a troll adam, its josh from atkins.
Ohhh that JOSH. Ok well if I had drawn the association of your name with our friendship I would have totally caught the wise guy humor. I guess Ill have to see your posts in true light from now on. HaHa. Talk soon Josh
Hey Adam, nice build! I enjoyed watching your work on the classic 79 RX7. Had a couple suggestions on the videography. The fade in and out on the stills was a bit much especially as fast as you cut from scene to scene and the written description didn't last long enough for me to read it, so had to back up and pause, which is no big deal, just interrupts the flow. Otherwise, excellent work. You guys did a bang up job on the custom fab work. I know how much effort we put into building the Turbo RX8 project car with all the custom fab work. I agree with the other comment about the air filter sucking hot air off the heat exchangers needs to be corrected. I don't know why anybody would spend so much money on a build like that (or any build for that matter) and not want to protect the engine and maximize performance as much as possible by avoiding inhaling hot air. I guess he won't really be able to use even half the power its capable of with stock 14" wheels, so hot intake air probably won't make a difference in his application. Gonna melt the rubber right off the rims if he nails it thought. LOL..
Hey Richard hows it goin? you know what funny...when my editor was done with it and I finally watched the entire thing....I picked out the exact same things. I mean exactly those 2 points caught my attention and thus mentioned to him. We agreed it was a bit too late to change it now...especially since we had already taken it down once and reposted. If it wasnt for that repost already I actually would have leaned toward re-doing it. FYI all the vids we have done so far are rushed using from unfinished B-roll. I have never put in full effort due to time. We have the capability to do this with very high end equipment so from my view...nothing I've done so far it what I see as top professional work. Its a balance of time ..as Im sure you can understand. Love the advice...keep it coming!

The oil pan had 3 deeper areas (chambers). Won't the oil just sit in 2 of those deeper areas (except the oil pickup) until the oil level is so that it spills over to the oil pickup chamber? Is the oil level sensor in the pickup chamber, if not then it's quite pointless to have the sensor as it always reads full.
NB! Much respect for the assembly and being able to fit this monster under the hood!
You guys are awesome, I've loved the wankle since 10th grade engine shop
Thank you for the content you're very informative about this I like it and I mean I learned a lot watching what you doing thank you very much
OK so these guys are the experts- but I didn't see any lubrication on the rotor bearings, are they really supposed to be assembled dry or was that step not shown?
1:02:57 Yep! That startup sounds exactly like a "5L3393R"....
That is a amazing job u guys did I've seen theses motors but this is by far nice build sounds nice as well and a lot of time went into this motor for shore ...👍🏼👍🏼👍🏼
Thank you!
The word is re-lifted on the dowells pins. The housing are being permitted to walk.
Anyone who gets a tat of a rotor on their forearm, you know is hard fucking core rotary fan.
I love the way it sounds
Great video. I bought a rebuild kit from you guys a few months ago and was very pleased. Price was great and shipping was fast.
Out of curiosity, what are your costs to lighten, clearance, and balance a 13B REW rotating assembly (looking for a 9000-9500rpm redline). Just wondering for a future project.
Email me for further pricing please
RX7 Specialties what's your email address cause I'd like to get pricing too. I've got a 3 gen with a 3 rotor in it already but it's incomplete.

It's a sleeper until he pulls up beside you at a stop light. The loping engine is a dead giveaway. Would like to see it run the 1/4 mile.
Wish I had a $1 every time you mentioned “dowel”
loss interest in listening to this before they flipped the case because the build was not about "assemble" but about the "dowel" work this shop does. Nothing about the work he was doing to actual build the motor.
Good video @GarageTa1khaggard would love that.
O'Hell I could outrun that thing on my 18'volt Barbie Jeep on a half dead battery.Lol That's a really NICE build great work guys
you guys need to make more videos! love the content :)
more to come
