This BMW E90 was built to drift by Ahrenius Motorsport in Sweden. Under the fiberglass hood sits a turbocharged M50B25 inline-six built by MotoSpeed that produces 771 horsepower and 990 Nm (730 lb-ft) of torque to the wheels on 1.9 bar (27.5 psi) of boost. The engine features custom JE forged pistons, Nuke Performance fuel system, Ogge Racing custom intake, and Link ECU. It rides on a Wisefab front and rear suspension with HSD adjustable coilovers and M Series brakes. The sedan was recently sent to Auto-Gruppen to have a sequential transmission and Emtron KV8 ECU installed.
