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.

400 Horsepower RX-7 in Tokyo
Met up with a guy who has a 400 hp RX-7 when it's running at low Boost. To ensure the longevity of the engine
he's running his T04 turbo at about
12psin (very low Boost). It has 2
apex seals on a bridge port motor. He gave a demo on the freeway and
showed what it can do.
Building a 13B-REW
This is how a 13B engine is brought to life from the Mazda factory.

"Mazda Factory's veteran Engineer, Mr. Uchitani shows how Rotary Engines
are assembled. Amazing that each RE has been built by hand until 2003!"
