GSC P-D 4B11T 08+ Evo 10 Dual Mivec S1 Cams 264/264 Billet - 7010S1

The GSC Power-Division billet S1 cams for the Mitsubishi Evo X are designed for those with the stock turbo up to the 550 HP range.

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 20-50 WHP (depending on turbo) have been seen by simply bolting the S1 cams in. 

• Designed for a rev range of 3000-7500 RPMs
• The S1 cams work well on the stock valve springs
• Forged billet core
• Made 100% in the USA
