Forced Performance Subaru STi/WRX Black Turbocharger 84mm CH10CM Turbine Hsg External WG w/Oil Line

Forced Performance is well-known for building robust turbochargers for performance applications, and this unit for the Subaru STi and WRX is no exception. This turbocharger is designed to help your engine breathe more freely, allowing for increased power output. It features an 84mm CH10CM turbine housing, which is a key component in determining how quickly the turbo spools up and the overall powerband it can achieve. The inclusion of an external wastegate setup gives you more precise control over boost pressure, which is crucial for both performance and engine longevity.

This turbocharger comes complete with an oil line, ensuring proper lubrication for sustained operation. The larger 84mm turbine housing is often chosen by enthusiasts looking to make more top-end power compared to smaller housings, though it might result in a slightly slower initial spool. The external wastegate allows for better management of exhaust backpressure and boost levels, especially when you're pushing the engine hard. This setup is a solid option for Subaru owners looking to significantly upgrade their vehicle's forced induction system.

When installing a turbocharger like this, it's important to ensure all supporting systems are up to the task. This includes proper fuel delivery, engine management tuning, and an exhaust system that can handle the increased flow. Always refer to the manufacturer's installation instructions for specific details and recommendations to ensure a smooth and successful installation.
