The GSC Power-Division billet S1 cams for the Mitsubishi Evo 4-8 are designed for those with the stock turbo up to the 550 WHP stock location or aftermarket turbo kits. 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 3000-7500 RPMs
  • These cams work well on the stock valve springs with lower boost and RPM goals
  • Idle is slightly 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**
