Product Description

The BorgWarner 12809880000 turbocharger is a high-performance, universal aftermarket turbo designed on the BorgWarner Engineered-for-Racing (EFR) platform. Featuring a large 84/98 compressor wheel and a robust 74 mm turbine, this turbo supports a broad power range suitable for engines targeting roughly 300 to 800 HP when properly tuned and supported with appropriate fuel and engine modifications. The advanced dual ceramic ball bearing center section helps reduce friction and improve response, while the low-inertia turbine wheel promotes quicker spool and strong throttle feel across the power curve.

This unit uses a T4 turbine flange and an internal wastegate, making it adaptable for custom performance projects, motorsport builds, or engine swaps where a high-flow turbocharger is needed. It also includes integrated control features like a compressor recirculation valve (CRV) and boost control solenoid valve (BCSV) for improved stability and boost control. Because this turbo is universal and not vehicle-specific, installation requires custom piping, oil/coolant feed lines, and tuning to ensure proper performance and reliability. This product is ideal for experienced builders and tuners constructing high-output turbo applications on a variety of engine platforms.
