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.

Do-it-Yourself knowledge to rebuild the popular 13B rotary engine for a Series 6 Mazda RX7. This part will tackle the assembly of the engine. This includes preparation and fitting of seals, gaskets into rotor housing and end plates. This will show you how to assemble the engine block together correctly with the rotors and apex seals to the manufacturers tolerances and specifications. The final assembly of the engine is completed with standard tools and leaves them ready for the final part 4 'Setting the end-float'.
