  • GFB Hybrid BOV NZ

    GFB Hybrid Blow Off Valve

    $369.00 – $669.00

    Known as the “Hybrid”, this world-first became the flagship model of the newly formed company Go Fast Bits. The two venting ports of this revolutionary valve were staged on the body such that the recirc port opened before the atmo port, helping to prevent backfiring and stalling on cars with a MAF sensor, whilst still giving the signature blow off sound when the car is driven harder.

    GFB Respons Blow Off Valve

    $435.00 – $825.00

  • GFB WGA Wastegate Actuator WRX
    GFB WGA Wastegate Actuator WRX

    Wastegate Actuator WRX – GFB WGA 7304

    $265.00

    Wastegate Actuator WRX – GFB WGA 7304

    The GFB WGA Wastegate Actuator WRX is a high performance internal wastegate actuator designed to improve boost control on internally wastegated turbos. By using a significantly larger diaphragm area than the OEM actuator, the WGA has more control authority over the wastegate flap, meaning exhaust backpressure cannot override the flap position as easily, resulting in more stable and reliable boost control.

    Supplied with 3 springs and a unique turnbuckle pre-load adjustment, the base boost pressure can be configured and adjusted from 5psi to 24psi for the best possible boost control.

    The WGA features a longer stroke, shorter height, and more adjustment than its rivals.

    WGA part # 7304 is designed to bolt on to Subaru WRX models from MY97-07 with the factory TD04 turbo. The 5psi and 7psi springs are installed for a base pressure of 12psi, and the 10psi spring is included in the packaging for further tuning options.

    Please note that whilst this is a physical “bolt-on” product, it should be considered a tuning tool as it WILL increase boost pressure and therefore TUNING IS REQUIRED.
