IHI 9F002 Turbocharger upgrade per IHI VF48

We present the IHI 9F002 turbine, a turbocharger developed for the Impreza WRX STI and other Subaru models equipped with the EJ25 and other popular engine models worldwide and in North America. The IHI 9F002 features an oversized compressor and high-performance aerodynamics, allowing it to deliver high torque at around 3000 RPM and a power output of approximately 360 horsepower (depending on the boost pressure and engine tuning). The IHI 9F002 improves the performance of Subaru Impreza WRX engines such as EJ20, EJ20E, EJ20G, EJ25, EJ25E, EJ25G, as well as other vehicles from the Japanese automaker, thanks to its use over the years on various cars with the same turbine-to-manifold and gas outlet flange connections. This feature enables a “plug&play” installation of the IHI 9F002 on your car at an affordable cost! (Some adjustments will be required for fuel introduction, ECU management, and potentially upgraded injectors).
