Forced Performance Subaru STi/WRX Red Turbo 84mm CH10CM Turbine Hsg 18PSI TiAL MVI WG w/Oil Line

If you're looking to significantly upgrade the performance of your Subaru WRX or STi, this Forced Performance turbocharger is a serious contender. It's built around an 84mm CH10CM turbine housing, designed to improve exhaust flow and spool characteristics compared to stock. This setup is engineered to handle up to 18 PSI of boost right out of the box, thanks to the included TiAL MVI external wastegate, which helps regulate boost pressure for consistent power delivery.

The CH10CM turbine housing is a key component here, offering a good balance between quick spool-up and high-end power for spirited driving and track use. Forced Performance is known for its well-built turbochargers, and this unit is no exception. It comes complete with an oil line, ensuring you have what you need for proper lubrication, which is critical for the longevity of any turbocharger. This turbo is a popular choice for Subaru owners aiming for a substantial power increase beyond what a simple bolt-on modification can achieve.

Keep in mind that this turbocharger is not CARB approved and cannot be shipped to California. Proper tuning is essential when installing a performance turbocharger like this to ensure optimal performance and engine safety. You'll want to consult with a professional tuner to dial in the air-fuel ratios and ignition timing for your specific setup.
