Part 12: 13B Rotary Engine Rebuild - My 76 Mazda RX-5 Cosmo Restoration
Just as I promised last episode, it is finally time to build the engine!
Part 12 of my RX-5 Cosmo restoration covers the entire process of building
the 6 port 13B Mazda rotary engine. While this engine is a hybrid of GSL-SE
RX-7 and Cosmo parts, the process is the same for any rotary from a 12A to
a 13B NA, 13B turbo, 13B-REW or any
other variant of the 13B. This video shows the whole process of the engine
build, starting from measuring the rotors and covering everything else
including clearancing the side seals, assembling the rotors, complete
assembly the short block, setting the eccentric shaft end play and
installing the front cover and everything underneath it. It's probably the
most complete engine build video outside of what you can buy from the
vendors, and as such, is an hour long. After this one, I'm going back to
videos under 20 minutes. But for now, grab a beverage of your choice, sit
back, and enjoy.
Rotary Engine Breakthrough?
The Wankel engine always held out a lot of promise, but never was able to
fully deliver on those promises. It was never very fuel efficient, and the
Exhaust temperatures were very high.
But now an independent car tech thinks he has stumbled onto what held that

The Mazda Rotary Engine Part 2
Educational film by Toyo Kogyo about the Mazda Rotary Engine. Shows how the
Rotary engine works with comparisons to the Piston Engine. Also shows the
Mazda RX500 test vehicle on a banked circuit and the Mazda Cosmo Sport (or
110S). Originates from the late 60's.

Test Run - Twin Rotor Nitro Rotary Engine
Test run of my custom built mini Peripheral Port Rotary Engine. The engine
uses two OS 30 Wankel rotors, carbs and rotor housings. I custom designed
and machined the front housing, center housing, eccentric shaft, intake
runners and Exhaust. I began
designing and solid modeling the engine back in September '08 and recently
finished assembly after some recent tweaks. Most of the machining was done
on a mini lathe and a standard drill press. Now I just have to finish
tuning the engine and I will have a full video posted of it running. Just
happy to see all my hard work, time and money pay off.
