The 911 GT2 is powered by a 3.6 liter twin-turbo engine. Tuned up, the unit produces 608 horsepower. Power is sent to the rear wheels via a 6-speed manual. The folks over at 9ff gave the 911 GT some new turbochargers and camshafts.
BMW M6 Gran Coupe runs stock, so 560 horsepower from a 4.4-liter twin-turbo V8. Still a rear-wheel drive vehicle with a 7-speed Dual Clutch Transmission.
