the amazing car: 2010 Impreza WRX STI

Available for the UK market only, the Cosworth Impreza STI CS400 was announced in late May 2010. Only 75 units built, the STI CS400 is powered by a 400 PS 2.5 liter turbocharged engine which has Cosworth engineered forged connecting rods, racing pistons, heavy duty cylinder head studs, multi-layered head gasket, and high pressure oil pump. The ECU had been remapped, and the new compressor design and wastegate actuator had been applied to the turbo. The exhaust system features larger capacity tubular manifold and bigger diameter downpipes. Clutch was also upgraded.
