Forced Performance has a solid reputation for building well-made turbochargers, and this XR Blue series unit is no exception. The 73HTZ designation points to a specific aerodynamic design within the compressor and turbine wheels, optimized for a broad powerband. The internal wastegate is a practical feature, helping to regulate boost pressure effectively without the need for external plumbing, which can simplify setup and reduce potential leak points. The included oil line ensures proper lubrication, a critical factor for turbocharger longevity. This turbo is intended for the driver's side (D/S) installation.

When considering a turbocharger upgrade of this caliber, it's important to note that other supporting modifications may be necessary to fully realize its potential and ensure engine health. This includes fuel system upgrades, exhaust modifications, and proper engine tuning. Due to emissions regulations, this turbocharger is not CARB approved and cannot be shipped to California.
