BMW E46 with a Turbo 4G63

BMW E46 with a Turbo 4G63 inline-four

This menacing BMW E46 was built by Gabura Motorsport in Miskolc, Hungary for professional drifter Gy├Ârgy Szilveszter. The E46 came with many engine options but apparently none of them would be used for this project. Instead the team decided to install a 2.0 L Mitsubishi 4G63 inline-four with a complete Cosworth 2.2 L stroker kit. The engine produces 650 horsepower thanks to a Garrett 3076 GTX turbocharger, Bosch 1800 cc injectors and a MoTeC M800 ECU. Behind the engine is a Tractive six-speed sequential gearbox connected to a BMW M5 E60 driveshaft and rear end with 3.90 gears. Ever effort was taken to reduce weight such as installing lexan windows and carbon fiber doors resulting in a weight of 2,469 lb (1120 kg).
