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 # 7300 is designed to bolt on to Mitsubishi Lancer Ralliart models with the factory turbo. The 5psi and 7psi springs are installed for a base pressure of 12psi, with the 10psi spring included in the packaging for additional tuning options.
Read on for more technical information on wastegate springs, and how the correct spring selection can improve performance.
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.
