Engine Performance: System: Turbocharger: Description
The Starion turbocharger is mounted on the exhaust manifold on the right side of the engine. Components of the turbocharger include turbine and compressor impellers, impeller shaft, bearings, impeller housings, wastegate controller, and wastegate. See Fig 1 . Engine oil pressure provides constant lubrication to the impeller bearings.
The pressure actuated wastegate, located at the front of the compressor housing, prevents excessive intake boost pressure. An additional safety feature is provided by the fuel injection Electronic Control Unit (ECU). The ECU will modify fuel injection pulse width when it senses intake manifold pressures that are higher than normal.
