Forced Performance Subaru STi Green UHF Turbo 60mm Black Housing External WG w/Oil Line (D/S Only)

This is the Forced Performance Green UHF turbocharger, specifically designed for the Subaru STi. It features a 60mm compressor wheel and a black housing, incorporating an external wastegate for precise boost control. This turbo is built to handle increased airflow and deliver more power than the stock unit, making it a solid choice for STi owners looking to significantly upgrade their engine's performance. The included oil line ensures proper lubrication for the turbo's rotating assembly.

The Green UHF is a well-known upgrade for the STi, offering a good balance between spool time and top-end power. Its 60mm compressor wheel is larger than stock, allowing it to move more air, which is crucial for making more horsepower. The external wastegate setup, paired with the correct tuning, provides more consistent boost pressure compared to internal wastegates, especially at higher boost levels. This helps prevent overboost and ensures the engine operates within safe parameters. The black housing gives it a distinct look under the hood. It's important to note that this turbocharger is not CARB approved and cannot be shipped to California.

When installing this turbo, ensure you have the necessary supporting modifications and a proper ECU tune. This includes potentially upgrading fuel injectors, fuel pump, and exhaust components to match the turbo's increased airflow capabilities. A custom tune is essential to optimize performance and reliability. Always refer to the manufacturer's installation instructions for specific details regarding oil and coolant line connections, as well as exhaust and intake manifold mounting.
