The fixed vane turbocharger is attached to the cylinder head with four studs and nuts and a multi-layer steel gasket.
The turbocharger has two exhaust gas inlets and two nozzles. The smaller sharper angled inlet is for quick response and a larger less angled inlet is for peak performance.
The turbocharger is equipped with ball bearing for the better drive. The ball bearings provide significant performance improvements to the turbocharger, improving the vehicle transient response. The ball bearings are also more efficient than standard journal bearing.
There is a turbine bypass actuator fitted on the top of the compressor housing by three bolts. The turbine bypass actuator opens and closes the turbine bypass valve between the exhaust inlet and outlet chambers. The turbine bypass actuator contains a position sensor beside the actuator motor. The position sensor and the actuator motor are connected to the Powertrain Control Module (PCM). The actuator is controlled by Pulse Width Modulation (PWM) signal from the Powertrain Control Module (PCM).
