Rotary 20B turbo Mazda RX-7 - Promaz Automotive
Charles' Promaz Mazda FD RX-7 runs a personal best pass at Heathcote. The
triple rotor stock import engine sounds great and certainly spices things
up. Boost comes from a Garrett
GTX42R turbo on just 13psi Boost, MicroTech LX12 computer running on
regular pump 98-octane unleaded. The drive-line still remains factory RX-7
issue and on the day saw Charles break not only a gearbox but also a
driveshaft. [ http://www.promaz.com.au ].

manifold. Custom made slide throttle body system. A world first however is
the use of a center main bearing and 4-piece eccentric shaft. Quick specs-

rotor bearings, ceramic NRS 2mm apex seals. Custom stationary gears, Full
custom Peripheral Port in each rotor housing (defined auto), Aluminum side
