GSC Power-Division billet S1 cams for the Mitsubishi DSM/EVO1-3 are designed for those with the stock turbo up to the 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 30-55 WHP (depending on turbo) have been seen by simply bolting the S1 cams in.
Designed for a rev range of 3000-8000 RPMs
300-450 WHP camshaft
Tapped for 98' DSM cam trigger
Idle is slightly rougher than stock
Upgraded valve spring recommended
Made 100% in the USA
**If using aftermarket cam gears (especially AEM) check the bolt length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case**
