Evo 9 Camshafts

GSC Power-Division billet 7009S2 cams for the Mitsubishi Evo 9 are designed for those with a goal of 400-700 WHP. No low end power is lost vs. the stock cams when used with the larger turbos. The S2 cams will show gains of 50-70 WHP over the stock cams, and in some cases more in the higher RPMs. Great for 2.0L engines with stock frame turbos revving to 9000 RPMs or for stroker motors revving to 8000 RPMs. GSC Power Division 9 Mivec Camshafts The S2 cams are suggested to run on our upgraded beehive valve spring replacement or can be run at the stock revlimit and factory boost on the stock spring.

• Designed for a rev range of 4000-9000 RPMs (2.0L or 3000-8000 2.2L+)
• 400-700 WHP applications
• S2 cams can run on Factory ECU with custom flashing
• 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**

GSC Power-Division billet 7009R1R is designed to rev between 3000-7500 RPMs for use with a 34-36mm Restrictor. The peak lift and aggressive profile design will require upgraded valve springs.

GSC Power Division Billet R2 Cams The billet 7009R2 is a high lift, very aggressive profile with a short overall duration to keep a lower usable RPM band. The 7009R2 is designed to rev between 4000-8500 RPMs and should be used with a stroked engine or added displacement engine. The peak lift of 12.10mm intake and 12.00mm exhaust will require upgraded valve springs and a titanium retainer with special attention to seal to retainer clearance. With the lift of this profile, it is suggested to only use the 5041/5040 Ti retainer and spring kits due to valve seal to retainer clearance. The 5041 can be used to 40+psi and the 5040 to 32psi on the R2 profile at 8500 RPMs without float or flutter issues. The profile will work fine on the OEM rocker arm and the zero-tick lifter or with the OEM lifter. We have seen gains of 25-30 WHP over the S2 profile on the stroked applications, with much more possible when used with a ported head and aftermarket intake manifold.

GSC Power-Division billet 7009S3 cams are a hydraulic lifter profile for the Evo 9 4G63. These cams are meant for 700+ WHP to take advantage of a very large turbo. These are NOT suggested for anyone running smaller. GSC Power Division S3 Camshafts 4G63

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. GSC Power Division Mivec S1 Camshafts
