The owner of this BMW E36 built it to drift on the weekends in Spain. Under the hood sits a turbocharged 2.0 L Cosworth YB inline-four from Ford Sierra RS Cosworth. The engine makes around 270 horsepower thanks to Ford Sierra XR4x4 injectors, Bosch 044 fuel pump, and Stage 1 ECU chip. Power goes to the rear wheels through a rebuilt BorgWarner T5 five-speed manual transmission with a ceramic clutch, modified driveshaft, and rebuilt BMW 188 mm differential with 4.10 gears. The owner also improved handling with reinforced rear subframe and trailing arms, roll cage, HSD Monopro coilovers, and 330i E46 brakes.
