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.
Part 7: My 76 Mazda RX-5 Cosmo Restoration - Intake and Exhaust Porting
Has it been nearly a month since my last episode? Wow, time does indeed
fly. I've been quite busy preparing to build the engine. So in part 7, I
cover the intake and Exhaust porting.
The engine is being built with GSL-SE 6 port plates and the Cosmo rotor
housings as the basis for a 6 port turbo
setup. This port job is fairly conservative, only opening up the primary
ports a little and bringing the Exhaust ports close to 2nd gen RX-7 specs. The
goal is to maintain fuel economy, low and midrange torque, and idle
quality. This episode covers everything involved in porting including:
marking out the new ports, grinding the port shape, smoothing the bowls,
smoothing port to runner transitions, smoothing the runners, grinding and
blending the Exhaust ports.
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.
Pro Turbo at Brisbane Jamboree
These guys are a cross between Pro Stock and Top Doorslammer and they're
the quickest machines in the Sport Compact world. Powered by mega-horsepower sixes and rotors
(and one V8) they're awesome to watch in action as they run six second
quarter mile times without a pushrod in sight. These are all the Pro turbo runs from Brisbane Jamboree. Three
rounds of Chicago Shootout with a final pairing at the end.
