For those of you performing an engine build, and looking for camshafts that are going to increase the performance throughout the entire RPM range, then consider the GSC Power-Division Billet S1 camshafts.
These are the perfect cam range for those of you running the stock turbo, or plan on staying under 500WHP. Although upgraded valve springs are required, the Beehive valve springs are recommended, but not required.
Please note that these are for the USDM models with AVCS.<. . . Show More >
