GSC Power-Division billet S3 cams for the Mitsubishi Evo 1-3 and first and second Gen DSM cars. The billet S3 cams are designed for those running larger turbos - 67mm and larger.
- Designed for a rev range of 4500-9500 RPMs
- GSC Beehive Spring and retainer kit strongly suggested
- 600-1000 WHP camshaft
- Idle is rougher than stock
- 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**
