Internal Wastegate Actuators

GFB's brand new and hotly anticipated WGA is a high performance internal wastegate actuator designed to improve boost control on turbo systems with an internal wastegate.

When diving into the world of increasing your cars boost pressure, the limits of a factory-fitted wastegate actuator can soon become apparent. Even with electronic boost control it is not always possible to overcome wastegate issues such as boost drop off at high RPM, unstable boost curve, or an inability to achieve target boost.

Upgrading to a GFB WGA ensures you get the best possible performance and response from your turbocharger!

GFB Wastegate Actuator for the Mitsubishi EVO 4-8

GFB

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 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.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.
