Introducing the WGA: Your Boost Control Companion
The WGA is a top-notch internal wastegate actuator crafted to enhance boost control on internally wastegated turbos. With a diaphragm area that's significantly larger than what you’d find in the OEM actuator, this little powerhouse offers superior control over the wastegate flap. This means that pesky exhaust backpressure won’t easily mess with the flap position, leading to a more stable and reliable boost experience.
Customizable Boost Pressure
Included with the WGA are three springs and a unique turnbuckle pre-load adjustment. This allows you to configure and tweak the base boost pressure anywhere from 5psi to 24psi, ensuring you get the best boost control tailored to your needs.
Designed for Performance
What sets the WGA apart? It features a longer stroke, a shorter height, and more adjustment options than its competitors. It’s designed specifically to fit the EVO X models with the factory turbo. The package comes with 10psi and 7psi springs already installed for a base pressure of 17psi, plus a 5psi spring for those who love to fine-tune their setup.
Key Features
- The most compact wastegate range available!
- Body, valve, seat, and all mounting hardware are CNC machined from high-temp stainless steel.
- Actuator housing is CNC machined from billet 6061 aluminum.
- Features a Nomex-reinforced silicone diaphragm for durability.
- An internal shroud protects the valve stem from excessive heat and prevents carbon-related sticking.
- Utilizes a V-band clamp mounting system for secure installation.
- Manufactured in Australia under ISO 9001 standards.
Fitment
- Mitsubishi EVO X 4B11T (2007-2016)
Important Notes
- While this is a physical "bolt-on" product, remember that it serves as a tuning tool. It will increase boost pressure, so tuning is essential to get the most out of it.

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and frequently released new models to expect eventual failure and discard something when it stops working or is superseded.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.
