The WGA, Wastegate Actuator is a high performance internal wastegate actuator designed to improve boost control on internally wastegated turbos. By using a significantly larger diaphragm area than the OEM actuator, the WGA has more control authority over the wastegate flap, meaning exhaust backpressure cannot override the flap position as easily, resulting in more stable and reliable boost control.

Supplied with 3 springs and a unique turnbuckle pre-load adjustment, the base boost pressure can be configured and adjusted from 5psi to 24psi for the best possible boost control.

Read on for more technical information on wastegate springs, and how the correct spring selection can improve performance. 

The WGA features a longer stroke, shorter height, and more adjustment than its rivals.

WGA part # 7301 is designed to bolt on to EVO 4-8 models with the factory turbo. The 10psi and 7psi springs are installed for a base pressure of 17psi, with the 5psi spring included in the packaging for additional tuning options.

Please note that whilst this is a physical “bolt-on” product, it should be considered a tuning tool as it WILL increase boost pressure and therefore TUNING IS REQUIRED.
