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.

Russian Rotary Vane Engine
Rotary Vane Engine proposed to power Russian hybrid car 'ё мобиль'
Rotary Engine Breakthrough?
The Wankel engine always held out a lot of promise, but never was able to
fully deliver on those promises. It was never very fuel efficient, and the
Exhaust temperatures were very high.
But now an independent car tech thinks he has stumbled onto what held that

roamed the streets at night. A few badass Supras, swapped & turbo'd nissans, GT-R's, Corvettes, twin turbo 350Z, a bike all came out to play on short
notice making for quite a night of street racing!
Turbo Peripheral Port Start-up and Idle
To the Youtube 'tards: This was a quick first start up video before
everything was assembled. The intake plenum, tubing, and coolant lines were
installed after the bugs were worked out.
13B Peripheral Port LOUD!!!
Some guys 13B Carbbed Peri-port rotary starting and revving at our mazda
car show. Car is a 83 Mazda GLC. It was VERY VERY LOUD in person. I
couldn't even hear him hitting the rev limiter
Peripheral port 13B idle
Homebrew 13B at idle; fabricated ports, header, intake manifold, etc,
breathing through a Weber 48 IDA.
Trying some tricks with porting and header design and it only fired up for
the first time about an hour ago, so I have no idea of power output, and
very little desire to make unrealistic guesses.
