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.
Mazda RX3 (Godfather) & Datsun 1200 drag race.
Mazda RX3 almost hits the wall. The RX3 is known as the Godfather, it runs a 20B rotary engine. The other car in the race is a Datsun 1200 ute from Jett Racing, fitted with a Mitsubishi 4G63. Action was captured at Jamboree 2011 @ WSID (Western Sydney International Dragway) Eastern Creek, N.S.W. Australia.
