03-06 Evolution 8 & 9 GSC Power-Division Camshafts

GSC's Power-Division high-performance camshafts for the 4G63T powered Mitsubishi Evolutions are engineered to offer the absolute best performance. Power-Division has stepped up their game with the S-Series cams for the Evo 8 and 9. With the wide array of profiles Power-Division has a cam combination to fit your needs. From a stock Evolution 8 to a fully built MIVEC monster, GSC's Power-Division S-Series cams can add power where you need it. GSC's Power-Division also has two differnt valvetrain upgrade options for when you are installing an S2 cam. You can choose from a single spring kit alone or the Stage 2 single spring, retainer and valve seat upgrade.

Stage 1 cams are designed for stock up to smaller upgraded bolt-on turbos (GT30/50 Trim). 30-55 WHP gains are possible. Stage1 cams will not sacrifice any bottom end power over stock cams. Slightly rougher idle. Works with stock valve train.

Stage 2 cams are designed for GT35 to GT40 sized turbos and won't give up bottom-end power when used with an upgraded turbo. 50-70 whp gains. Excellent in high-revving 2.0L or stroked 2.2L motors. Upgraded valve springs and retainers required. Tuning is also required to properly run these cams.

The GSC Stage 3 Cams are available in a solid lifter cam and a hydraulic lifter cam for the Evo 8 4G63. These cams are meant for the 1000whp+ to take advantage of a very large turbo. These are NOT suggested for anyone running smaller than the GT42R and should not even be considered! Upgraded springs, retainers and tuning are a must.
