GSC P-D 4G63T Evo 9 Mivec S1 Cams 268/268 Billet

7009S1

The GSC Power-Division billet S1 cams for the Mistubishi Evo 9 are designed for those with a stock turbo all the way to a GT30/50 trim. 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 25-40 WHP (depending on turbo) have been seen by simply bolting the S1 cams in.

• Designed for a rev range of 3000-8000 RPMs
• These cams work well on the stock valve springs
• 300-450 WHP camshaft
• 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**
