Turbocharger

The Blouch 18G-XT turbocharger is engineered for Subaru WRX/STi models, offering a proven blend of advanced billet compressor aerodynamics and reliable journal bearing technology. This turbocharger is capable of producing up to 430 horsepower, making it a significant upgrade for performance-oriented vehicles. Its design incorporates a custom Blouch Turbo compressor housing, CNC machined for optimal fitment with the 18G-XT aero. The compressor wheel itself is constructed from closed-die forged, fully machined billet, ensuring it is both lighter and stronger while providing enhanced flow rates. Key internal components include a water-cooled journal bearing center housing for efficient operation and a custom high-flow, low-inertia TD05H turbine wheel. Buyers can select from three turbine housing options—7cm², 8cm², or 10cm²—allowing for tailoring to specific application needs. Additional options include a 3-inch bellmouth inlet compressor housing and an upgrade actuator. The Blouch 18G-XT is highlighted for its rapid spool characteristics, substantial mid-range torque, and excellent top-end power relative to its size. It is specifically recommended for those aiming for 430 crank horsepower. It is critical to note that THIS PRODUCT IS INTENDED FOR RACE-ONLY COMPETITION VEHICLES.
