The Garrett G57 turbine housing kit with 1.41 A/R uses V-band inlet and outlet connections and is intended for G57 turbocharger builds where a larger A/R ratio is desired. This housing changes exhaust gas expansion characteristics to influence turbo behavior. The V-band in/out configuration supports straightforward assembly and integration with compatible G57 cores.
