The displacement was increased to 3.2 liters and the motor was mated to a five-speed M3 transmission. Lightweight forged JE pistons were set onto Pauter connecting rods and attached to a knife-edged crank. The DOHC engine head was polished and ported and sculpted to accept larger intake and exhaust valves. Custom fabricated headers and exhaust piping were also utilized.
While these changes certainly gave the M3 motor more grunt, what tops the intake manifold is what earns the engine its place under the hood. The 3.2-liter is force-fed by a Stage 3 Vortech V1 supercharger with an air-to-liquid aftercooling system. With a re-mapped ECU and the ability to run nearly 16 psi of boost, Demmitt estimates the motor will generate 500 screaming horses. Using the supercharger with the stout inline six actually gives the car more horsepower than that produced by the factory GTR 4-liter V8s.
So, if you find this particular M3 filling your mirrors, heed your survival instincts and move over. Way over. Because Demmitt is going to pass you. He just needs the room.
