FYI: Greddy turbos are Mitsubishi units (slightly slightly different), in the same vein that Turbonetics are Garrett by make... and yes, i prefer the Turbonetics units as they seem to have pretty competitive prices, clocking on almost every model, and numbering which makes sense.
Mazda used Hitachi turbos on the RX-7's. Most upgrades for the 7 are a Garret. It just about picking the right compressor and turbine sizes. The rotary needs a much larger turbine size than a piston motor.
