Turbosmart's new Twin Port Internal Wastegate Actuators bring a new dimension of control to the R35's twin-turbo setup. Whereas traditional internal wastegate actuators utilise a single pressure port to operate the actuator, Turbosmart's Twin Port actuators feature a second pressure port to a separate chamber.

The pressure differential between the two sealed champers creates a dynamic force that overcomes the spring force inside the actuator. The result is a new level of boost control that can rival an external wastegate, with a smoother and more responsive boost curve under all operating conditions and a greater range between maximum and minimum boost than a conventional single port actuator.Ê

The Twin Port for the R35 GTR is a direct fit replacement for the standard wastegate actuators.

The kit includes two Twin Port IWGs for the R35's two turbos and a custom-designed bracket and rod, meaning all the benefits of superior boost control are available without any custom fabrication or special tools.Ê
