Forced Performance Subaru STi Green UHF Turbo 84mm Black Housing Internal WG w/Oil Line (D/S Only)

This package includes the Forced Performance Subaru STi Green UHF Turbocharger, featuring an 84mm black housing and an internal wastegate. You also get the necessary oil line, specifically for the driver's side (D/S) application. This turbo is designed to be a robust upgrade for your Subaru STi, offering improved airflow and performance over stock units.

The Green UHF turbo is known for its ability to handle higher boost levels, making it a popular choice for those looking to significantly increase their engine's power output. The 84mm compressor housing is a key component in its enhanced airflow capabilities, allowing for more air to be pushed into the engine, which translates to more power. The internal wastegate is pre-set and integrated into the unit, simplifying installation compared to external wastegate setups and helping to maintain consistent boost pressure. The included oil line is crucial for proper lubrication and cooling of the turbocharger's rotating assembly, ensuring longevity and reliable operation.

When installing this turbo, it's important to ensure all supporting modifications are in place to take full advantage of its capabilities. This often includes upgraded fuel injectors, a high-flow fuel pump, and an engine management system (like a standalone ECU or a reflash of the factory ECU) to properly tune the engine for the increased airflow. Proper oil feed and drain lines are essential for the turbo's lifespan; this kit includes the driver's side oil line to get you started. Please note that this turbocharger is not CARB approved and cannot be shipped to California.
