BMW E46 with a Turbo 4G63

Published in engineswapdepot.com

This menacing BMW E46 was built by Gabura Motorsport in Miskolc, Hungary for professional drifter György 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).
