Introducing the WGA: Your Go-To Wastegate Actuator

The WGA is a top-notch internal wastegate actuator designed to give you better boost control on internally wastegated turbos. With a diaphragm area that’s significantly larger than what you’d find in the OEM actuator, the WGA offers more authority over the wastegate flap. This means that pesky exhaust backpressure won’t easily override the flap position, leading to more stable and reliable boost control.

Customizable Boost Pressure

Equipped with three different springs and a unique turnbuckle for pre-load adjustment, you can easily configure the base boost pressure anywhere from 5psi to 24psi. This flexibility ensures you get the best possible boost control tailored to your needs.

Designed for Performance

The WGA boasts a longer stroke, a shorter height, and more adjustment options than its competitors, making it a standout choice for performance enthusiasts.

Compatibility

Part # 7304 is specifically designed to bolt onto Subaru WRX models from MY97-07 that come with the factory TD04 turbo. The 5psi and 7psi springs are pre-installed for a base pressure of 12psi, and you’ll find a 10psi spring included in the package for even more tuning options.

Important Notes

• Keep in mind that while this is a physical "bolt-on" product, it serves as a tuning tool. It will increase boost pressure, so proper tuning is required.
