Forced Performance Subaru STI XR Blue 73HTZ Turbo 58mm Black Housing Ext WG w/Oil Line (D/S Only)

Forced Performance is well-known for building high-performance turbochargers, and the XR Blue 73HTZ is a prime example of their work for the Subaru STI. This turbocharger is designed to significantly increase airflow to your engine, offering a substantial upgrade over the stock unit. It features a 58mm compressor wheel and a black housing, giving it a distinct look while housing serious performance potential. The integrated external wastegate helps manage boost pressure precisely, ensuring consistent power delivery and protecting your engine.

This turbocharger is built with a focus on durability and performance. The 73HTZ designation often refers to specific aerodynamic improvements within the compressor and turbine sections, aimed at improving spool-up time and overall efficiency. The inclusion of an oil line is crucial for proper lubrication and cooling of the turbocharger's rotating assembly, which is essential for longevity, especially under demanding conditions. This unit is specifically configured for the driver's side (D/S) installation, meaning it's designed to fit within the tight confines of the STI engine bay with that orientation in mind.

When considering a turbocharger of this caliber, it's important to note that it's a significant modification. You'll likely need supporting modifications such as an upgraded fuel system, exhaust, and tuning to take full advantage of its capabilities and ensure the engine runs safely. This turbocharger is not CARB approved and cannot be shipped to California due to emissions regulations.
