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 RX7 Rotary Engine Failures
MAZDA RX7 Rotary Engine Failures MAZDA RX7 rotary engines are strong and displace a lot of power for their size. Traditionally, carbon deposits and heat are their biggest enemies. Rotary engines run with a huge temperature differential, meaning that one side of the engine runs cooler that the combustion side (side with the park plugs). As a rule, cooling system damage should be avoided at all costs. Learn how these issues affect rotary engines and what kind of damage is done to them when they really fail. Presented using advanced software CG animation technology to help you understand. Part of our Automotive Technology Rotary Wankel engines and MAZDA RX7-RX8 series shown here on this channel.

Turbocharged RX-8 engine teardown and rebuild
http://blackhaloracing.com/ With three days to pull the engine, rebuild it and reinstall, is Charles R Hill from Black Halo Racing (BHR) up to the task?! View the video to see what we find when the engine with 51,000 miles is pulled. More details and photos of this rebuild can be seen at: http://www.rx8club.com/showthread.php?t=148395 PS: I admit I didn't hold the camera stable enough for the first day of footage. Gave me a damn headache editing the footage.
