Forced Performance Subaru STI XR Blk 82HTZ Turbo 84mm Black Housing Int WG w/Oil Line (D/S Only)

If you're looking to significantly upgrade the performance of your Subaru STI's engine, a high-flow turbocharger like this Forced Performance XR 82HTZ is a key component. This unit is built to handle increased boost levels and airflow, which is essential for making more power, especially when you're pushing your engine beyond its stock capabilities. It's designed to replace your factory turbocharger, offering a substantial improvement in how your engine breathes and performs under load.

This particular turbocharger features a robust black housing for a distinct look and durability. The 84mm compressor wheel is a notable size increase over stock, designed to move a lot more air into your engine. It also includes an internal wastegate, simplifying installation by integrating boost control directly into the unit. The included oil line ensures proper lubrication, which is critical for the longevity of any turbocharger. This is a D/S (Direct-fit/Stock-location) model, meaning it's engineered to bolt up to your STI's existing exhaust manifold and downpipe flanges, making the installation process more straightforward than custom setups.

When installing a larger turbo like this, it's important to consider supporting modifications. You'll likely need an upgraded fuel system, an engine management system (like a standalone ECU or a reflash of the stock ECU), and potentially an upgraded intercooler to effectively manage the increased airflow and heat. This turbocharger is not CARB approved and cannot be shipped to California. Always consult with a professional tuner to ensure your engine is properly set up to take advantage of this turbo's capabilities and to maintain engine reliability.
