Show original supplier description

The Tomioka GTX2971R BB Turbocharger is engineered to deliver exceptional performance for Subaru Impreza WRX and WRX STI vehicles. Featuring a advanced ball-bearing design, this turbo provides crisp and immediate throttle response, comparable to larger performance turbos. Its billet compressor wheel is significantly lighter than traditional wheels, allowing for increased airflow and improved performance. The unique TR blades are constructed for unmatched durability, while point-milled blade surfaces ensure maximum flow efficiency. The exhaust housing is port and polished to reduce exhaust flow turbulence, further enhancing performance. This turbocharger is ideal for enthusiasts seeking quick spool times and the ability to run moderate boost pressures, supporting up to 500 horsepower. The package includes all necessary fittings and gaskets for a complete installation. Specifications include a standard Subaru 5-bolt flange, a 52.73mm intake / 75mm exhaust compressor wheel, a 55.63mm intake / 52.33mm exhaust turbine wheel, and a 1.3 Bar (19psi) actuator with a 10cm^2 turbine housing. This turbocharger is compatible with the following Subaru models: 2002-2007 Subaru Impreza WRX, 2004-2014 Subaru Impreza WRX STi, and 2015-2021 Subaru WRX STI.
