Forced Performance Subaru STi/WRX Red Turbo 84mm Black Turbine Hsg Internal WG w/Oil Line (D/S Only)

Forced Performance is well-known for building high-performance turbochargers, and this 84mm Black Turbine Housing unit for the Subaru STi and WRX is a prime example of their work. This turbocharger is designed to replace your stock unit and offers a significant upgrade in airflow and power potential, especially when paired with other supporting modifications. The internal wastegate setup simplifies installation compared to external wastegate setups, and the included oil line ensures you have what you need to get it plumbed correctly.

This turbo features an 84mm compressor wheel and housing, which is larger than stock and allows for increased boost pressure and airflow. The black turbine housing is built to withstand the high temperatures and pressures associated with turbocharging. The internal wastegate is precisely controlled to manage boost levels, helping to prevent over-boosting and maintain consistent power delivery. This unit is specifically designed for the driver's side (D/S) application, ensuring proper fitment and exhaust manifold alignment on your Subaru.

When installing a turbocharger of this caliber, it's important to ensure your engine is properly tuned to take advantage of the increased airflow and boost. Supporting modifications such as an upgraded fuel system, intercooler, and exhaust are often recommended to maximize performance and reliability. Please note that this turbocharger is not CARB approved and cannot be shipped to California.
