Go Fast Bits WGA 7301 Internal Wastegate Actuator
If you’re looking to dial in your boost control on your Mitsubishi EVO, the Go Fast Bits WGA 7301 is a must-have upgrade. This high-performance internal wastegate actuator is engineered to enhance the performance of your factory turbo by providing superior control over your wastegate flap. With a significantly larger diaphragm area compared to the OEM actuator, the WGA 7301 ensures that exhaust backpressure won’t easily override the flap position. This means you can expect more stable and reliable boost control, whether you're on the street or the track.
Key Features
- Compact design with the most efficient wastegate range on the market.
- Body, valve, seat, and all mounting hardware are CNC machined from high-temp stainless steel for durability.
- Actuator housing crafted from billet 6061 aluminum, ensuring strength and lightweight performance.
- Nomex-reinforced silicone diaphragm provides excellent thermal stability.
- Internal shroud protects the valve stem from excessive heat, preventing carbon-related sticking.
- Easy installation with a V-band clamp mounting system.
- Manufactured in Australia under ISO 9001 standards for quality assurance.
Fitment
The WGA 7301 is specifically designed to bolt onto the following Mitsubishi EVO models with the factory turbo:
- Mitsubishi EVO 4 (1997-1998)
- Mitsubishi EVO 5 (1999)
- Mitsubishi EVO 6 (2000)
- Mitsubishi EVO 7 (2001-2002)
- Mitsubishi EVO 8 (2003-2005)
Boost Pressure Adjustment
Equipped with three different springs and a unique turnbuckle pre-load adjustment, you can easily configure the base boost pressure from 5psi to 24psi. The actuator comes with 10psi and 7psi springs pre-installed, yielding a base pressure of 17psi, while the 5psi spring is included for additional tuning flexibility.

Important Notes
- This is a bolt-on product, but keep in mind that it acts as a tuning tool. Installing the WGA 7301 will increase boost pressure, so professional tuning is required to optimize your setup.
Customer Feedback
Mitsubishi EVO 8 owners have reported significant improvements in boost stability after installing the WGA 7301. One owner said, “After installing the WGA 7301, my EVO feels more responsive than ever. The boost holds steady even at higher RPMs, and I love the flexibility in tuning!”
Whether you're a track enthusiast or just want to maximize your EVO's potential, the Go Fast Bits WGA 7301 is a solid investment for anyone serious about performance.
