Today, Blouch Performance Turbo offers a complete line-up of custom performance bolt-on upgrades for popular vehicles such as the Subaru WRX/STi , Mitsubishi EVO VIII, IX and X, Porsche 996 and 997, Mitsubishi 3000GT, and Dodge SRT4 and Caliber. The components used in these upgrades are state-of-the art such as fully machined billet compressors with advanced aero, custom turbine wheel and shaft assemblies, and custom compressor and turbine housing castings that are machined in-house on their own CNC equipment.
