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.
Key Features
- Compact wastegate range that’s the best on the market!
- Body, valve, seat, and all mounting hardware are CNC machined from high-temp stainless steel.
- Actuator housing crafted from billet 6061 aluminum for durability.
- Nomex-reinforced silicone diaphragm for added strength.
- Internal shroud protects the valve stem from excessive heat and helps prevent carbon-related sticking.
- Easy-to-use V-band clamp mounting system.
- Proudly made in Australia under ISO 9001 standards.
Fitment
- Mitsubishi TD04
- Subaru WRX 1997-2007

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.

We live in a throw-away society, conditioned by cheap products and frequently released new models to expect eventual failure and discard something when it stops working or is superseded. However, pride in workmanship and our commitment to quality means that when we put our name to something, we are also staking our reputation on it.
That’s why we back our products with the best Warranty in the business! You should expect a lifetime of use from a well-engineered product, so if your GFB product fails as a result of defective materials or faulty workmanship whilst you remain the original owner, we will repair or replace it.
If the fault occurred as a result of usage outside of the terms of the warranty, or you are not the original owner, fear not, we can still help you. You should never need to throw a GFB product away, as spare parts are available and won’t cost the earth.
