GFB Internal wastegate actuator WGA for Subaru Impreza GT Turbo and 2.0 WRX (TD04)

Go Fast Bits (GFB) is an Australian ISO 9001 certified company established in 1997, developing and designing high performance products to enhance vehicles.

The entire GFB range is designed, tested and manufactured in Australia to ensure maximum and consistent quality.

The new WGA internal wastegate range has been designed to improve turbo pressure management with an internal device.

Original wastegates quickly find their limit when turbo pressure is increased, even for electronic models.
The new WGA internal wastegate ensures the best performance in all circumstances, even at very high engine speeds.

The diaphragm has been designed with Nomex reinforced silicone for better turbo pressure control with a larger surface and smaller diameter.
The WGA range is the smallest and most compact on the market for ease of installation.
The 18mm stem diameter allows for a very wide turbo pressure range without the need to replace springs.
The rod guide is made from a PEEK polymer and takes up less height, generates less friction and is more resistant to wear.
Supplied with three different springs to cover a pressure range of 0.34 to 1.51 Bar.

Advantages:
- Faster turbo charging
- Less pressure drop at high rpm
- More stable boost pressure
- Withstands and supports higher pressures
- Supplied with multiple springs

Suitable for TD04 turbo on :
Subaru Impreza GT Turbo from 1998 to 2000
Subaru Impreza WRX 7 from 2001 to 2002
Subaru Impreza WRX 8 from 2002 to 2005
