Forced Performance Subaru STi/WRX Green UHF BB Turbo 84mm CH8CM Turbine Hsg Internal WG w/Oil Line

Forced Performance has built a solid reputation for making serious turbochargers, and this Green UHF BB Turbo is a prime example of their work. This unit is built for Subaru WRX and STi models, designed to give your boxer engine a significant boost in power. It features an 84mm CHRA with a ceramic ball bearing core, which means it spools up faster and handles higher boost pressures more reliably than older journal bearing designs. The internal wastegate setup simplifies installation compared to external wastegate setups, making it a more straightforward upgrade for your vehicle.

This turbocharger uses a CH8CM turbine housing, which is a good match for the airflow demands of many performance-oriented Subaru engines. The ceramic ball bearing system is a key feature here; it reduces friction, allowing the turbo to spin up quicker and hold boost more consistently, especially at higher RPMs. This translates to a more responsive engine and a broader powerband. The package includes the necessary oil line, which is crucial for proper lubrication and cooling of the turbocharger's rotating assembly. Proper oil supply is vital for the longevity of any turbo, especially one with high-performance ball bearings.

When installing a turbocharger like this, it's important to ensure your engine's supporting systems are up to the task. This includes fuel delivery, engine management (tuning), and cooling. Because this turbo is not CARB approved, it cannot be legally shipped to California. Always consult with a qualified tuner to ensure your engine is properly managed with this new turbocharger to maximize performance and prevent damage.
