Key Features

  • 7cm² turbine housing: Strong mid-range and top end, with excellent response on 2.5L engines.
  • Factory orientation: Oil feed, oil drain and water lines sit in the factory positions for easy fitment.
  • Factory position: Looks close to a factory unit and uses the factory manifold and exhaust.
  • Billet actuator: GCG billet 14.7psi actuator, supplied with an extra 5psi spring to raise minimum boost to 19psi if required.

  • 1 x GCG GTX3071R turbocharger with billet actuator
  • Additional 5psi actuator spring
  • Oil feed, oil drain and water line kit
  • Exhaust studs and dump pipe locking nuts

Important Notes

  • The oil and water line kit suits most applications. Depending on the vehicle, some fitting work may be needed, such as: shortening the manifold studs, spacing between manifold and turbo, secondary air valve or tumble valve changes or removal, moving intercooler brackets, or clearancing the compressor housing.
  • A custom tune and matching supporting modifications are required.
  • Professional installation and tuning are strongly recommended.
  • Made to order – please allow up to 30 days.
  • Please confirm your vehicle's engine and turbo configuration before ordering.
