Key Features

  • Cast Turbine Housing: Durable NiResist material resists cracking under extreme exhaust temperatures up to 1050 degrees C.
  • Integrated Wastegate Actuator: Factory-spec 7 psi actuator maintains precise boost control without actuator upgrades.
  • Factory-Balanced Assembly: Rotates smoothly to 120000 RPM minimizing vibration and extending bearing life.

Product Notes

  • New turbocharger requires no core return or deposit.
  • Inspect oil and coolant lines for wear during replacement.
  • Packages in heavy-duty box to prevent shipping damage.

Installation Notes

  • Professional installation recommended.
