This Mazda RX7 four rotor SPO class race car was designed, built and raced by Toivo Heinonen, the Mazda Rotary Guru! This Rose Cup winner has an 80% tube frame chassis with adjustable dampers and ride height clothed in a custom fibreglass wide body kit.
This very fast car is powered by a brand new, dyno-tested and tuned four rotor straight port race engine, with crankshaft and hardware sourced from New Zealand and balanced in Puerto Rico. It has a Motec ECU with multiple fuel & ignition maps, is fuel injected (with port injectors and individual throttle bodies), and has a separate four coil ignition system, a custom thick wall '4 into 1' exhaust header with 3.5 inch stainless steel exhaust and extreme heat ceramic wool mufflers, and an external high pressure oil pump.
The drive train includes a five speed, sequential shift, close ratio racing transmission and a Ford 9 inch limited slip rear end. The brakes are Big Tilton four piston calipers with vented rotors. The logbooks, and all parts and spares, including the fibreglass moulds, extra wheels and tires, and a laptop for tuning come with the car. Toivo spent well over $125,000 on this car's engine and components.
