A Turbosmart internal wastegate IWG has the wastegate valve built into the turbine housing. The wastegate valve is controlled by an actuator which consists of a spring and a sealed chamber. The sealed chamber of the actuator is connected to a pressure only source normally on the compressor cover of the turbocharger.
