Forced Performance Subaru STi Black Turbo 84mm Black Housing 18PSI TiAL MVI WG w/Oil Line (D/S Only)

If you're looking to significantly boost the performance of your Subaru STi, this Forced Performance turbocharger is a serious upgrade for your forced induction system. This unit is built around an 84mm compressor housing, designed to move a substantial amount of air to help your engine make more power, especially at higher RPMs. It comes pre-configured with an 18 PSI TiAL MVI Wastegate, which is a popular choice for its reliability and precise boost control, ensuring your engine stays within safe operating parameters while maximizing performance.

The black housing gives it a stealthy look under the hood, and the included oil line is crucial for proper lubrication and cooling of the turbocharger's rotating assembly. This is a direct replacement for the driver's side (D/S) turbo on certain STi models, simplifying installation. Forced Performance is well-known for building robust turbochargers, and this unit reflects that reputation with its solid construction. The 84mm housing is a notable step up from stock, offering improved airflow that can lead to substantial power gains when paired with appropriate supporting modifications like an upgraded fuel system and engine tuning.

When installing a turbocharger of this caliber, it's essential to ensure all supporting systems are up to the task. This includes proper exhaust manifold fitment, an upgraded intercooler, and a comprehensive engine tune to take full advantage of the increased airflow. Because this turbocharger is not CARB approved, it cannot be legally shipped to California. Always consult with a professional tuner to dial in your engine's performance safely and effectively with this turbocharger.
