GSC Power-Division S1 cams for the Mitsu Evo 1-3 and first and second Gen DSM cars. The S1 cams are designed for those running a small 16G or large 16G turbo. These cams will not sacrifice any bottom end loss over stock cams; nothing but gains and will promote faster spooling of the turbo. Gains of 15-25whp (depending on Turbo) have been seen by simply bolting the S1 cams in. Designed for a rev range of 3000-8000rpms, these cams work well on the stock valve springs. 250-400whp camshaft.

Idle is slightly rougher than Stock
