GSC Power-Division Mitsubishi Evo (4G63T 9 Mivec) S1
GSC Power-Division's Evo 9 S1 cams are designed for those with a
stock turbo all the way to a GT30/50Trim. These cams will not sacrifice
any bottom end loss over stock cams; nothing but gains and will promote
faster spooling of the upgraded turbos. Gains of 25-40whp (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. Stock Turbo or small upgrade flat tq curve, up to 450whp.
