How the hell has the KZbin algorithm never delivered me this video in 6 freaking years??? Rotary? YES. Sleeper? YES. 700HP rotary sleeper? HELL YES.

[@Scrildo1]

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!

[@so2fast4u2]

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....

[@InsideOfMyOwnMind]

That's a hilarious analogy. In survival mode we tend to go for the lower tech solution. Primal?

[@mikesmith8278]

First four minutes just loved talking to himself.

[@caramelbear757]

that sounds like the first thing I'd buy if I win the lottery!

[@dakken74]

caramelbear757 that's exactly what I was thinking!! lol

[@grkpk123]

hard work pays off man

[@suckmydingledong]

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.

[@dangoe9908]

I agree.. Legalized extortion

[@84gssteve]

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!

[@southjerseysound7340]

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.

[@aslamkingtube1151]

I don’t own a rotary but I love watching these builds.

[@saultube44]

I have almost 0 clue about any type of combustion engines and yet I like the building and explanation of it, thank you.

[@ardyshane23]

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.

[@rx7specialties203]

Would be my pleasure

[@chancekoehler7578]

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

[@RoliRuli]

Yea but... use your hands = more pleasure

[@boocrafty8783]

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

[@ceirwan]

That sounds about as stealth as the Saturn V rocket lifting off!

[@davidvickers8425]

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.

[@Kenji1685]

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.

[@louisbosch2182]

I also have a 85 first gen that I want to build. this video is my dream build. is sounded wicked

[@geoffwallace8196]

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.

[@TheGildedMoose]

All hail Dorito engine power

[@Velikain]

First minute, the background, rotors, engine blocks, it's like rotary heaven.

[@rbmwiv]

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.

[@Machieavelli]

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

[@rx7specialties203]

You're very welcome...our pleasure!!

[@msattler111]

Amazing craftsmanship. The owner must have had very deep pockets to finance this work. Well done.

[@MrQuantom]

@@msattler111 4 Sure! $$$

[@Pieman6711]

One of my goals eventually is to put a 20b in my 1st gen. Thank you for the full build video!

[@manstersr]

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.

[@rx7specialties203]

Thank you!

[@k-aw-teksleepysageuni8181]

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).

[@nunolc2560]

What a sleeper this car turned out to be. Congrats!!!!

[@Gallardo6669]

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... = )

[@Stabfab]

You guys are awesome! My REC engine runs like a beast.

[@shanemb3]

Motor went together like butter. That's a tight build, literally.

[@jamieswain4888]

Shane Bigler literally? Well you didn't mean metaphorically did you? -_-

[@rx7specialties203]

Thank you

[@dfhj4556]

Don't know why but I found this video extremely relaxing and calming to watch..

[@XBullitt16X]

You know you really love rotary engines , when you have a rotor tattooed onto your arm lol

Earned a sub for it lol. Thats dedication

[@ToryonDavis]

For life!

Or Doritos :)

[@peterbustin8604]

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 !

[@rx7specialties203]

You're welcome

[@victorbernardi9248]

Incredible!. My favorite body style I miss mine. Love that swap

[@twcaldwell1951]

your exhaust manifold and turbo assembly is absolutely amazing. what a feat of engineering.

[@ViceVersaMusik1]

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!!

[@erussell1081]

WOWOWOW, never knew these type of engines sound so good

[@ThadmanKane]

Magnificent attention to detail and accuracy!

[@QuiquePR]

I love the Bridgeport sound, great project

[@stick6f282]

Wow, Pure artwork. Thank you.

[@AntiPattern328]

You guys are the bomb! That is awesome how much fabrication and custom work you do. Very impressive!

[@rx7specialties203]

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

[@rx7specialties203]

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.

[@luchacefox259]

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

[@rx7specialties203]

Great suggestions and we have agreed to do this in the near future. Once we get the big projects posted on KZbin and the customer requested videos taken care of as we go, we will aim to go more in that direction. Stay tuned!

[@deniseanderson3521]

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.

[@followthegrow108]

RX7 Specialties hello is there an email i can reach you at? Or a number. Please and thank you.

[@dylanmccallister6739]

The background at the start, my god. So pretty.

[@johnnysantiago393]

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

[@rx7specialties203]

Thanks!

[@daymoon8482]

What a sick build

[@starvalkyrie]

Sleeper that lopes like a top fuel dragster and revs like a chainsaw. I think they're gonna know something is up captain.

[@RobertKohut]

Great video!! Love the sound and love the idle!!

[@bobbyshaftoe45]

Fantastic Build Walkthrough! Thanks to you guys and the Owner :-))

[@rotaryminds8360]

Wow great work! All the custom work to keep it a sleeper like the oil pan is especially good.

[@kennethdefreitas3120]

Awesome video man rotary engines so much less complicated than conventional internal combustion engines

[@fc3sking119]

very nice build,now I know we're to go for my 85 gsle drag build, very nice build,thank you for sharing

[@rx7specialties203]

Your welcome and look forward to helping you out someday

[@emmanueltucker3696]

Im so excited to have my rx7

[@kilerfire5]

They really built a very impressive piece of art, thank you for sharing

[@rx7specialties203]

your welcome

You guys are awesome, I've loved the wankle since 10th grade engine shop

[@brapdaddy]

I just finished watching this. very very very! inspiring.

[@rx7specialties203]

Glad you enjoyed

[@somsaksomprasong583]

The rotary engine is awesome!

[@willierule3744]

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

[@michaelbutler9866]

I love the way it sounds

[@3toedSloth75]

Would love to see more build videos like this

[@franzkoviakalak6981]

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.

[@rx7specialties203]

Look forward to helping you

[@767dag]

Beautiful work and build !!

[@markwallace5274]

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 !!!!!!

[@rx7specialties203]

Glad you enjoyed it!

[@emmanuelquinones6421]

Perfect job guys 700hp nice sleeper two thumbs 👍up

[@strider_hiryu850]

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.

[@rx7specialties203]

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

[@maidenlord6663]

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

[@StormCentre88]

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.

[@RickSaffery]

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!

[@rx7specialties203]

Thanks for the kind words. Glad you enjoy watching!

[@RaimoJackson]

Great work!

[@donniebaker5984]

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.

[@odertube]

Excellent video. That engine sounds awesome.

[@rx7specialties203]

Thanks for watching..glad you enjoyed it

[@tambo264]

RX7 Specialties is it wise to have a air filter near the rads where hot air blasts at it .

[@odertube]

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.

[@rx7specialties203]

No not at all but tight for space. Owner might build some sort of cold air duct soon

[@marxmann3564]

RX7 Specialties where is your shop located

[@Internationalmanofmysteries]

Beautiful craftsmanship. Kudos.

[@rx7specialties203]

Thanks a lot!

[@prime-eight]

There's almost no way to turn a 3 rotor into a "sleeper". Maybe when it's parked....

[@hoost3056]

If it had a street port and a quiet exhaust, absolutely sleeper. This combo is too rowdy....but wow! Excellent job!

[@hribc78]

haha, right? more like the neighborhood menace

[@emmanuelquinones6421]

It purrrrrrsssss that sounds so nice great job job keep up the good work

[@consciouscool]

Your shop does good meticulous work. Great job.

[@rx7specialties203]

Appreciate that thank you

[@SufferingAddict88]

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.

Wish I had a $1 every time you mentioned “dowel”

[@dahamby9590]

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.
