Adding a supercharger and increasing displacement to 4.6 liters boosts the M3 to supercar levels of power and performance.
Aresing-based tuner G-Power recently released photos of a BMW M3 Coupe (E92), the owner of which was in the market for a serious boost in performance.
As such, they opted for the Tornado RS conversion, which consists of taking apart the 4.0-liter V8 and rebuilding it with a new crankshaft and Mahle pistons, raising the displacement to 4.6-liters. Next, the company's Sporty Drive SK III supercharger system was added along with a carbon-fiber air box and titanium exhaust with carbon tips.
The result is an output of 720 horsepower for a 0-62 time of 3.7 seconds and a 205.5mph top speed. A Clubsport adjustable coilover suspension kit and G-Power's 20-inch Silverstone Diamond alloys were added for improved handling and stability, while the project was completed with some aero elements, namely a lower front spoiler, and replacement hood and boot lid made from carbon fiber.
