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

Starting with an 84mm compressor housing, this Forced Performance Green UHF turbocharger is built for serious Subaru STi performance. The black housing isn't just for looks; it's a durable finish designed to withstand the heat and grime of high-performance driving. This unit features an external wastegate setup, which gives you more precise control over boost pressure compared to internal wastegates. It also includes an oil line, a critical component for keeping the turbo properly lubricated and cool under demanding conditions. This turbo is specifically designed for the driver's side (D/S) installation, meaning it's configured to fit that side of your engine bay.

The 'Green' designation from Forced Performance typically signifies a well-known and popular upgrade path for Subaru enthusiasts looking to significantly increase horsepower. The UHF (Ultra High Flow) aspect points to an updated design focused on maximizing airflow, which is essential for generating more power. This turbocharger is a substantial upgrade over stock, intended for those rebuilding or significantly modifying their engine's top end. Proper tuning will be absolutely essential to take full advantage of its capabilities and ensure the longevity of your engine and the turbo itself. Because this is a high-performance component, it's crucial to ensure your supporting systems—like fuel delivery, cooling, and exhaust—are up to the task.

It's important to note that this turbocharger is not CARB approved and cannot be shipped to California. For optimal performance and reliability, always refer to the manufacturer's installation instructions and recommended tuning procedures. This is a component for those looking to push the boundaries of their Subaru's performance.
