Mazda RX3 13B rotary turbo - Promaz Automotive
Ross' immaculate Mazda RX3 runs into the 9s for the first time. The new car
is powered by a Promaz Automotive 13B bridgeport rotary engine and aided by
a Garrett turbo and MicroTech EFI. Ross
has fitted an Albins gearset to the Mazda RX-7 gearbox. The RX3 was only
on low Boost this time out so expect
the guys to run a lot quicker yet.

2hp: Mazda 6 VS Honda Accord
Today we'll compare Mazda6 and Honda Accord. Mazda has
become more attractive, masculine and aggressive, at the same time Accord
has grown up and has become more heavy and ambitious.
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.

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.
