Engine Performance: System: Turbocharger: Description

The turbocharging system is mounted on the manifold side of the 2.2L engine. It includes a turbine assembly, center housing rotating assembly, compressor assembly, wastegate, and throttle body. The turbine is spun by exhaust gas causing compressor wheel to draw in air.

Maximum manifold pressure (boost) is controlled by the exhaust wastegate. Operation of the wastegate is controlled by a solenoid and the Single Module Engine Controller (SMEC).
