- FullBOOST Tech Files, Ep 1 ~ Rebuild and Bridgeport of a 13B rotary engine @ Mr Parts.
We have started with a stripped down 1984 Mazda RX7 13BT engine, and will run through the steps involved in bridge porting the engine, then assembly, to the start up in its new home, a 1972 Mazda 808 (RX3).

Having only worked on piston engines, this was very enlightening. I had basic knowledge of the internals of a rotary but now understand what makes a 2 and 3 rotor engine. You just gotta love the simplicity of it all. BTW, nice RX-3, as it is known here in the States.
Just watched a whole rotary being assembled and they STILL seem like black magic.
Wow. This was a really REALLY good rebuild video. Wasn't all over the place and confusing. I feel like going out and getting one just to rebuild now. lol
Mate, feel the same.
I have an s2k that I daily yet have always loved the rotary engine.
Would need to be a secondary car as I couldn't cope not getting to work in the case of a rebuild.
If only funds weren't an issue. :)

Buy a focus se. lol. Bullet proof little cars with a manual trans and if you get a CVH do the valve seats and you'll see 400k before you know it.
itd be cool is this process did actually take 24 minutes and 12 seconds.
You can rebuild one and put it back into the car in a day if you know what you're doing.
Only if you want to blow your tips off
🤣🤣🤣
@@boblecocojames you give us hope
keep this guide, because you will need it every 40,000 to 75,000 miles!
got 160000km at my last build buddy
@@seanstrange69 still nothing to brag about...🤪
Unfortunately you are correct...
I've watched a bunch of rebuild video's and this one is easily one of the best! Awesome work guys!!
OMG! Thank you! Such a nice build video. I used to have a 1973 Mazda RX 3 Wagon that the previous owner cut the roof off of, because he wanted a convertible! Soon after doing that, he discovered that the vehicle flexed way too much without the roof , so he had his local shop weld in a custom full roll-cage. Then he had the 12B rebuilt for high performance and did some minor suspension work. It had a Wink Mirror and DAMN! that thing was so much fun to drive, especially in the early eighties when the congestion wasn't too bad... Rotaries love to rev, not like pistons that have the whole: up, stop, down, stop BS. Rotaries, once they get going, just want to keep winding up. I remember the over rev buzzer all too fondly and miss my old, what some had termed, Road Warrior Car...
Rotaries Rock!!!!
This was absolutely the best video so far!! Great job!
Thanks for posting this. Always wanted to see the rotary engine dissected.
Thanks for putting this video together, its been really interesting to watch.
I'm Old School Rotary Junky And This Video Is Well Done!
Great video. Nice to see a motor put together and explained how and why it was done.
Awesome video and beautiful vehicle!
YES! More of this kind of stuff Fullboost! Can never have enough rotary!
bloody awesome video guys. Thanks so much for posting. Watched it all the way through.
That was really cool! I have always wanted to see how one of these engines is rebuilt. The car that it went into is very beautiful and I love the paint color. Thanks for sharing
This is a great resource on bridge port. I always hear about bridge port in rotaries, but knows nothing about it. Now i know! Thanks!
that was one of the best things I have seen on UA-cam for ages.
Have you guys got any other porting videos
Thanks for that. I've always been fascinated by the 'other' type of engine but not had a really good understanding of how it is put together.
Fantastic video! I think this is a great addition to your channel, straight forward, easy to understand and to the point. I really hope these videos take off. Great work and thanks!
Thanks for the positive feedback everyone. We'd like to do more videos like this.
THANK YOU,GUYS...Making it easy for those that we LOVE Rotary....
This was very cool! Never knew how these motors worked. Thanx.
That engine sounds so sweet! Can’t wait to get my own one🥰
Excellent video guys, a mine of information. Cheers, I feel my upcoming rebuild is in good hands now!
man rotary engines are cool, I so need to try one of these babies out! Thanks for sharing this.
Awesome video! It was really easy to understand the process.
I really enjoyed that and it sounds amazing
Excellent video,I was facinated and at how intricate these things are!
Top job mate.. Clean and organised..
Brilliant Video !!!!
great job the engine sounds amazing
What a marvel... Lots of delicate looking seals...I know they work well but Im still surprised. All in all definitely fewer parts than a normal piston engine. I really need to pick up a 13B or two and marry them together... This looks very easy and my understanding of the rotary has moved a bit further because of this engine rebuild video....and you just GOTTA LOVE a rebuild video that ends under the hood and running for us...SWEET... Nicely done!
That was awesome !
keep up the great work man
Best video on engines I have ever seen
Chris McEvoy thanks, we have a few more coming, and hopefully by the end of the year we will start work from scratch on a project car so make sure you subscribe to the channel!
+MrParts_RotaryRaceCars
No, you was very disrespectful to the other guy above asking about the seal.
We will not subscribe to people like you who think that they are entitled to mistreat people whenever they feel like.
People, look for aaroncake here on you tube, he has a very good series of videos about rotary engine rebuild.

*you were
matt williams shhhhhhhh... kid
juan cabeza Lol sissyboy don"t get your panties all bunched up in there.
Great video i really enjoy it and learn a lil bit more about rotary engines
Amazing!! These engines are much more simple than a piston engine I like it now you need to do a video on how to turbo one of these
awesome video, i love your in depth videos with engine builders and narratives, showing the portwork and many internal parts of a rotary i did not know existed, also filling alot of blanks, thank you for taking the time! as always!
Sloppy Mechanics hi Matt
Awesome vid! Wish I could get a hold of one to play with.
rotary enige sounds very clear nice done
Really great video. Well done.
excellent vid, first class !!
Great, informative video - good job!
that was Beautiful !
Fantastic video. Thank you for sharing.
OMG great video, have to try this sometime haha but seriously, really good learning video. Thanks!
Brilliant video!
Such an informative video. Cheers guys.
Awesome video. You make it seem like anyone could go do this easily
Beautiful engine, beautiful car!!
Please make more instructional videos like this, I think these videos provide a lot of in depth technical information for motorheads like myself
@ 22:49 you can hear why the rotary never "took off". Don't get me wrong. I absolutely LOVE these engines. That sound you hear is actually the engine losing a LOT of it's compression when the apex seals hit the plug holes. Fantastic video! thanks...
The best tutorial ever!!!!
Outstanding video cheers
Fantastic video . Thank you
Great job man.
Watching this makes me want to install a rotary into an old pickup with a failed engine just to have some fun. Thank you.
Sweet video man keep it up
AWESOME.... more like this
Well made video. Cheers.
Great vid guys
Very Helpful 👍
Tops vid. Really detailed. Cheers
Hey man thanks for this vid.
sweet video, guys.
Nice Job!!!
Badass instructional video, very detailed
nice job... sounds mint
Great Video :)
Very nice guys
The tail lights are 🔥🔥🔥🔥
awesome video. Thanks!!! Love rotary
Interesting stuff.
Nice to watching
outstanding work! also that is one of the nicest sounding engines i have ever heard..
Wonderful, Well done
I could watch shit like this all day!
Not in the rotary engine crowd but this video was very precise and detailed!
Good shit man )
0_o I'm speechless. Rotary is an art to rebuild for damn sure. very good walk-through video.
Very good excellent very good 10/10 👌
Nice video, thanks!
However - for clarification to anyone not aware...
When installing the oil control rings into the rotor, the notch side not only needs to go down, but the notch must align with the squared tab end of the spring.
You were clear about the other side - the rounded end of the spring being positioned into one of the small holes in thew rotor, but you did not mention the notch needs to align with the spring as well.
Thanks again for sharing!
Hi. I have just bought a mazda RX5 -77 and i'm going to overhaul the motor, i wonder where you recomend buying all gaskets and apex. Thanks!
Rickard from Sweden
good video
would this build be the same for the rx8 engine?
Love to know the power numbers this engine makes.
I built a model Wankel long ago, even read a book on them, great idea, but it was never intended for making huge power numbers, glad some do.
Wonderful ..
Thanks for the info, especially regarding the D-shaped exhaust port. I suspected that would be the best design, but I wasn't certain. I was also intrigued to see how you milled the faces of the rotors to prevent scuffing against the housings at high RPM. I plan to use this info to modify the tiny rotary engine in one of my RC cars...if I ever get that car up and running in the first place.
I have a question, though: Are the scoops in the faces of the rotors really the best way to transfer the fuel charge from the cold side of the housing to the hot side of the housing? Or would it be better to have channels cut into the housing at the point of maximum compression, and use non-scooped rotors instead? It seems like non-scooped rotors would do a better job of thoroughly evacuating the exhaust gases, and also minimize port overlap regardless of the port design.
My first car was a first gen rx-7, i also got an A+ in "advanced" auto shop class in hs for rebuilding an engine for it...
I remember how much "fun" getting those seals in place was, the corner and the side seals were a serious pita.
Back then (96), there was not nearly as much available as there is now, however i spent lots of time browsing those mazda trix catalogs dreaming...
Makes me almost want to pick up another one of those cars.
And i think transmission assembly gel would work much better holding everything in place when assembling. ;)
They even have different grades depending on how much hold you want vs temperature.
Lov it ! Thx
Excellent video and description! You need to show is how to do PP rotary now please, thanks.
That' looks even less complicated than a 2 stroke.
Thats exactly what I just wrote in my comment, about 3 or 4 comments up ☝! But that is so true! I feel like I can build a Rotary after watching a couple people building them in different videos. The ONLY place where I would get mixed up at is when you have to start adding all the parts that attach to the engine, Like the A/C and all that, but even that looks slightly easy... depending on what your adding, because this is a clean N/A setup. But yea man.. . . I was thinking the same damn thing!
Nothing is less complicated than 50cc 2 stroke
@@ViceVersaMusik1 haha the assembly is easy its the measuring of all the tollerances on everything.... otherwise engine will not last and fail
Yup, I'm thinking of doing it myself too even though a shop I found, was charging me 800 which is not bad but I like trying new things!! With this video I'm sure I would be able to do it I just wouldn't fire it up. Unless it was getting tuned right away.
damn fine video
lovely
nicely explained video...now i want a roatary engine to disasemble and put together again :P....didn't know they were that simple... :) have done some disasembly and reasembly of volvo enginges in my early days.... :)
they are not as simple as you think...
it takes alot of time and patience
They are simple just tedious
Mean video man . inspired me to build one.
killer! post up some photos in the new fullboost group on facebook facebook.com/groups/FullBOOST/
in need of one!
@fellowship of the goat, The Corner seal and Side Seal run along the Bridge, If you had one big port in the side the seals would fall in and it wouldn't end well.
