Product Information

See Turbosmarts Installation Guide Here

The Turbosmart IWG75 Internal Wastegate Actuator is a direct-fit performance upgrade designed specifically for BorgWarner EFR B2 turbochargers, suitable for both single scroll and twin scroll configurations.

Developed to deliver the maximum possible boost response from factory-frame turbochargers, the IWG75 Series features a significantly improved working ratio compared to OE actuators. This is achieved through a larger effective diaphragm surface area combined with optimised spring selection, providing greater leverage against boost pressure and exhaust backpressure while remaining highly responsive.

When upgraded using the same base pressure as factory, the IWG75 actuator delivers earlier boost onset, a broader torque curve, and improved boost stability through higher RPM. These gains can be further enhanced with higher base pressure springs, though ECU tuning or boost control recalibration may be required.

This version is supplied with a 14 PSI base spring, making it well suited to high-performance street and motorsport applications using BorgWarner EFR B2 turbochargers.
