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.

Peripheral port 13B idle
Homebrew 13B at idle; fabricated ports, header, intake manifold, etc,
breathing through a Weber 48 IDA.
Trying some tricks with porting and header design and it only fired up for
the first time about an hour ago, so I have no idea of power output, and
very little desire to make unrealistic guesses.

Mazda RX3 tags the wall - MRHELI
King of the 2-step, Frank 'Mr Heli' Canistra hasn't raced the RX3 in some 2
years. The 13B rotary turbo powered
Mazda sedan ran strong all day going into the low 8s but got loose late in
the night. Frank did a great job of steering out of what could have been a
heavier hit and the good news is that he walked away unhurt.
