I had never watched your videos before, and thought you were a shop down in the US, but I spotted an old Canadian Tire ratchet and had to check your website. Cool to see some great rotary tech in Calgary!

I love that you explain everything

This is a very cool build, I bet them rotors are worth there weight in gold. I always love these out of norm builds that people do. Good work on the video and very cool to keep all us KZfaq watchers in mind when building something like this!

You guys should make a rew swap kit for the rx8 you guys would profit a lot

I appreciate the real time aspect of this video. for the most part. If some are bored by this, then they really aren't that interested in the subject. Their loss.

Me and Brandon always talking about the good old 12a love to see your build bro and with that garret gtx ur gonna use this motor is going to be a beast 👋✋✋✋✋🤘🏻🤘🏻🤘🏻🤘🏻🤘🏻💥🔥🔥🔥

You guys have something to chase if Brandon is going drag racing...Mr 12A Bill Nabbhan ran 7.96 @ 169 mph in an untubbed RX3 a few years ago...GOOD LUCK!

Is this Bob Ross of the rotary builds?

This is EXACTLY what I have been wanting to do to my FB!

This is absolutely professional, I have nothing but, awesome!

I think the way you stud the motor makes sense, mostly because you are sorta preloading the studs slightly with the your tool before completely assembling the motor and torque them.

I have a pair of 12A housings still in the box. Never used them. Nice video. There is a 12A Rx8 that runs in the 6's in Puerto Rico

Awesome build... definitely a really cool rare engine. You talk about the studing a lot and it got me thinking I own that tool that you're using and I only use it to remove studs. intake manifold exhaust manifold studs etc ( most vehicles use an E-socket for installation of the new stud)... because when you go to reinstall them you leave marks indented into the threads and I was thinking about it. if you're using that and then trying to get an accurate torque how does that work? that's why you have to tap the tool off after loosing it is because it's clamping onto the threads and distorting them. I agree with everything you talked about far as your stud kit... just not to use of that tool. I think it's kind of funny that you're right about everything that you talked about far as your stud kit but you're ruining the studs threads. I could even see the little lines from the tool on a couple of the studs. FYI that's why ARP studs have an allen built into the top of the stud cuz the only other way to do it would be the way you're doing it but it would ruin the threats.

Mass produce and Make a kit or atleast full build sheet with part# and CNC cuts files. We would even pay for just that.

I think it's great the kind of stuff you guys do there... It put me to shame what I know about these kind of cars compared to what you know... For example I ordered an rebuilt motor core from Mazda auto recycling in CA I think, this was about 12 years ago. I had a foreign car shop here in Sioux Falls put in the motor... They couldn't get it started, I had to get running myself... At the time the pulsation damper was bad which caused the previous motor to go bad by washing out the motor with fuel... Once I replaced that it work great, over a $100 part. Before that I had to disconnect electrically the fuel from the rear of the car... The car be was a major pain in the ASS, I got rid of it... I envy people that have the patience for these cars... I am still waiting for the RX-9 to come out...

That was a sick 12ABPT build video mate! Love your work!

It's not boring... its fascinating!!

I did this back in 1998., but with s5.x12at mix. Custom machined combustion reseses 12a s3 rotors went in the 1999 motor and Cosmo endplates. THE SCIENCE OF SPEED OH IN 1994 I did 12a turbo with 13b turbo manifolds and 13b s4 turbo unit in my rx3 coupe the first in Aust 2nd was an r100.

There's been a 12A running 6's at the 1/4 mile for over a year now 😌 #thepuertoricansatitagain

Love your work guys.

And I’m just discovering this. Instant sub

I love a good 12A. Hopefully Mazda will start re-manufacturing housings for them, as mine is starting to look like it may need a rebuild sometime soon.

Great video, very professional!

That was fun. Thank you.

Great video always learn something new.

The engine looked beautiful 😀

Thank you!

awesome job guys!!!

Most early RX's in Australia run a shortened Toyota Hilux rear end.

Nice work

hi just a bit of a idea. Can you show the rest of the motor being put together in one of the next videos, like the oil pump, thermal pallet, end float being checked, and front cover going on. Thanks for showing the videos.

Great workmanship. Very profesional

Yes.. please do rx8 swaps/upgrades.

Love the rotary!! Awesome content!

I love 12A.... ΠΡΑΟΥ.....

@RX7 Specialties you should leave a link to your website so i can go over and get some apex seals

Come on. Go peripheral!

I am curious, how do you know exactly where the farthest point of the tip of the rotor goes??? Which is now pointing down at the the base of the motor....

You should sell the stud tool with your stud kit.so you don't have to do extra machine work,for Allen holes.as people will probably use the wrong Allen wrenches and strip holes lol, just a thought...

Who would guess YT recommended this on NY 2021

How much to get a set of those modified 13b housings for 12a?

Would you perhaps build a 4roter engien ko live in Sweden. Right now but wen. Jive in California if i don’t fixstjärna it by my self

I really enjoy your videos. I've never used a rotary engine. Way back when rotary engines were new they gained a negative reputation for fuel consumption, burning oil and lasting very long. From your videos, I see that these things can be attributed to the badly designed apex seals. I plan to use a 3 rotor turbocharged engine made especially with aviation in mind. Constant speeds and way better-designed apex seals. I have a question. Mazda designed the older engines to burn 4 stroke oil from the crankcase. But now people speak of using a mix of 2 stoke oil in remove the oil metering device and using the ashless 2 stroke oil. 4 stroke oil, for some reason especially in aviation engines, 4 stroke oil leaves significant metallic deposits. I think something to do with the synthetic attribute of the engine. Using a pure non-synthetic oil like Briggs & Stratton 2 cycle oil is inexpensive and burns without leaving ash. So is mixing with a good ashless, non-synthetic oil the better way for the longer-lasting rotary engines. I asked one of your website people and he just told me when he uses and says I should use it too. This phenomenon of burning leaving a lot of metallic ash was noted using aviation engines. Would you please tell me what you would use so your engine should get better lubrication of the apex seals and fuel burns clean, leaving little to no deposits? I had a stroke 18 years ago and used to be comfortable doing my own mechanics including regular maintenance and engine rebuilds. Now I have to build trust with mechanics before I have them do work on my car. I'll need an entire engine since I have none. How much gph should I expect cruising with my newly rebuilt rotary engine? About how much hp should I get out of 3 rotors and double turbocharged engine? Thanks !!! I'm sorry I don't know your name.

Can you do a video of 12a twin dizzi housings and ports .

so guys ive been watching him rebuild these engines for awhile. did i miss something on why the studs need O-Rings installed before the washers are added. i know oil flows though the other holes in the irons, is that why the O-Rings were installed?

Excellent 👌🏻

Quisiera saber porque o por donde es la fuga de aceite hacia la cámara de combustión y el exceso de humo y consumo de aceite...

You’re a genius 😭😭😭😭😭

Love it

Are you using 1 or 2 piece apex seals?

I thought studs weren't supposed to be tightened down into the block as there only supposed to stretch on one axis?

I want to know where I can get the studs for a 12 motor to Kevin that you assembled it to a motor

What word be the cost to build a high HP 12a n/a

Hey any follow up on this one?

These dudes got parts y I can't find them so I can buy some

Great wrk. Truly gtret

You know this guy is a true rotary fan when he got a rotor tattoo on his forearm lol diehard

Interesting video! I'm curious, how come you put locktight on the ARP nuts instead of ARP's own assembly lubricant? Does the nuts have a higher risk of loosening up than for example the nuts to a cylinderhead on a piston engine?

what was the outcome of this build?

Hello, I do enjoy your videos. I need an engine, 3 rotors, dual turbo rotary engine to be used for an aviation engine. I know some govt entities haven't certified rotaries, but there are many happy owners of aircraft that has a rotary engine. My plane weighs about 2,500 lbs empty. I need an engine that has the extra things done to it like you always make. If you have any suggestions as to what services you think would be needed in an aircraft engine. I won't be pushing it hard except takeoffs and will have a reduction gear so I don't have to rev the engine all the time. Can you give me some suggestions on what you think you'll need to do to put this engine together?

Sucks to think these guys probably went out of business by now

Such an excellent video. Hopefully you are still responding to comments if not I'm calling you up to find out. So was just wondering, if you were to run a quad rotor N/A with 12A rotors and housings (24A) and wanted to have a Liberty Pro-Stock Z-style transmission for a drag application. Would the FD auto rear plate and bell housing still be the preferred set-up? Thank you in advance.

Hope you realised before you sent it out that you never put sealant on the rear legs. Brandon will be pissed if you didn't... !!!!!!

Hey I am rebuilding my 1981 rx7 12A rotary. Would love to know a good place to get the rotar housings and irons

why no one piece dowel pins

what is the hp difference between a bridgeport + turbo rotary vs just turbo/street port + turbo rotary assuming engine is otherwise the same including turbo size

is it possible or wise to widen the slot on the rotors sides seal insert to accept and run 12a/rx8 side seals for the 86+ 13b?

I didnt see the motor on the stand, so when i see it start to tilt, i thought it was falling

Verry nice work and a lot of power ,I would like to the to know about the stud you are using if you have them for sale got two 12A and one 13B motor to build do you have company phone number to call you up thanks.

Hello there's any video on this car already running ill bet a lot of us wants to see it

Brandon hu? Let's Go Brandon!!!

How can i buy an engine for RX8, i'm in México and need one for standart car, thanks

What kind of dusting goes on the stators?

Please adopt 3D printing

Boa noite!! Oi tudo bem? Eu quero comprar um motor rotativo, eu sou Brasil(português)🇧🇷

Where are u located at

Does a bridge like this still produce the iconic lumpy idle ?

You guys have a video of peripheral port or semi?

Hows the motor getting on?dynopower just gave mine a retune for upcoming season.e85 606hp atw

Why do everyone us silicone on the housing in the bottom of the screen area? There is nothing important :o

Would it say 13b on the housing still?

んっちぇんっちぇって喋るの耳に触るｗ 12aフルパワーって書いてあったで期待したのに、「んっちぇ」を聞いてるだけという・・・

Interesting bridgeport, why such a small eyebrow?

A question for you.. What was the assembly lube you used on the front gear? It looks really tacky and perfect for the engine I'm building.

Why such a small bridge port

why not just do a stage ported 13b and piss past 600hp on pump gas? like the green brothers do here in nz.

Umm, that's actually a J Port...

Water-Meth injection?

Amazing video! Follow the builder Brandon Stockellburg on Instagram for more updates on his build of his first gen 12a Savanna!! 12a_savanna_project

Hate to see this build cost.

Hello you I’m going to by Mazda rx7 “old” yes but not that old.ongien I like the rotary engines and I don’t like the piston engines. I like them more than the piston engines o’ej I just like them they maid me like engines... i’m from Sweden 🇸🇪 I like engines how they are builti,,, I’m a boy” ore a man that want to have rotary engines not only.but it’s just the howsing and rotarying no o-rings on colvs

Boring!!! Am doing the same thing as you step by step ohh baby !!!!!!!🥳🙇🏼‍♀️🥳🥳🥳🤣🤣🤣🤣🤣

When you say a "first-generation car that was an original 12A vehicle"...I assume you mean an RX7? Or an RX4?

I have a new idea only no many No trying to implement of my idea New engine creations impeller engine

Lip slapping an smacking. Lmmfao

Hjgihjhh

Hondabond on a Mazda how dare you 🤣

Whack engine..This is a tiny little bridge.I can show u some real porting on a 1974 13 b streetport that i have.Its a street port that behaves like a bridge with powerband from 5500 rpm to 9450 rpm.And a 10.500 rpm redline.But i never took it past 9500rpm .No Joke.No shop will give u the secrets...NO ONE....
