Performance Machining and Turbo S400 Turbocharger

PMT offers a wide line of performance S400 based turbochargers built with the latest and greatest. Our race cover has a larger A/R than the standard covers you see on most Borgwarner turbos, providing better flow for the bigger compressor setups. The Cover also features a built in velocity stack for maximum horsepower effort and is a direct replacement fit for #171702 Style compressor covers used in many of the popular plumbing kits on the market today.
