An exhaust driven turbocharger includes a wastegate valve which is operated by a pneumatic actuator mounted on the outer edge of the compressor housing. A portion of the linkage interconnecting the actuator with the wastegate valve includes a flexible cable which is routed around the edge of the turbine housing, around the center housing and over the outer edge of the turbine housing to a lever which operates the wastegate. In alternate embodiment, the axis of the actuator extends substantially parallel to the axis of the turbocharger, and the flexible cable is looped around the end of the turbocharger and extends across the center housing to engage the lever actuating the wastegate valve.
