Show original supplier description
The Blouch 18G-XT turbocharger is engineered for Subaru WRX/STi applications, aiming to provide a balance of quick spool, strong mid-range torque, and excellent top-end power. It utilizes the latest billet compressor aerodynamics paired with a water-cooled journal bearing center housing for reliability and performance. Key features include a closed-die forged, fully machined billet 18G-XT compressor wheel that is both lighter and stronger for increased flow. The turbine side uses a custom high-flow, low-inertia TD05H wheel. Buyers can select from 7cm², 8cm², or 10cm² turbine housings to best suit their specific application, and an optional 3" bell mouth inlet compressor housing is available for enhanced airflow. This turbo is capable of supporting up to 430 crank horsepower. This product is intended for race-only competition vehicles and is not street-legal in the United States. Installation on a vehicle registered for public road use is a violation of federal law. It is the responsibility of the user to comply with all applicable federal and state laws regarding the use of this product.
