GFB Internal Wastegate Actuator for Mitsubishi Lancer Evo 10

Internal Wastegate Actuator for the Lancer EVO X

Designed to bolt on to EVO X models with the factory turbo

The WGA 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 back-pressure 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.

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

Designed to bolt on to EVO X 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.
