Product Information

See Turbosmarts Installation Guide Here

The Turbosmart IWG75 Series upgraded wastegate actuators are engineered to deliver maximum boost response and control for factory-frame turbochargers, particularly BorgWarner EFR applications. Designed as a direct upgrade over OE actuators, the IWG75 range offers a significantly improved working ratio, resulting in faster boost onset, stronger mid-range torque, and more stable boost control across the RPM range.

This improved working ratio is achieved through a larger effective diaphragm surface area combined with carefully matched spring revisions. The result is increased leverage against boost pressure and exhaust backpressure forces, while maintaining excellent sensitivity and response.

When upgraded with the same base pressure as factory, users can expect earlier boost achievement and a broader, more consistent torque curve. Higher base pressures are available to further extend performance potential, though ECU tuning or boost control recalibration may be required.

The Twin Port design expands boost control capability by allowing pressure reference on both sides of the diaphragm. This enables advanced boost strategies, including forcing pressure into the top cap for higher boost targets or under the diaphragm for lower boost targets. Twin Port control allows the use of softer springs, improving boost dynamics, response, and overall drivability.
