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.

wankel turbo ski race boat
owner has opined, boat is going 105 here but has done 118! That's pretty
fast in a boat that size, especially with the chine walk it's doing.
Driving this would be like laying a 2x4 across a bowling ball and trying to
balance yourself, on ice!!! And people waterski behind these too!!!
