GSC Power-Division billet L3 cams for the Evo 4-8 4G63 using a solid lifter conversion. These are meant for Higher RPM 800+ WHP to take advantage of a very large turbo.

**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 7008R3 is designed to rev between 6500-10500 RPMs and can be used with a stroked engine or stock 2.0L displacement engine. This profile is best suited for topend power for drag and standing mile style setups. The peak lift of 12.0mm intake and exhaust will require upgraded valve springs and a titanium retainer. It is suggested to run the GSC5078 or gsc5079 Ti retainer with conical spring..

The profile will work fine on the OEM rocker arm and the zero-tick lifter, or with the OEM lifter. 

**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 7008R1 is designed to rev between 3500-7500 RPMs and can be used with a stroked engine or stock 2.0L displacement engine. This profile is best suited for quick throttle response and midrange power being the main target powerband. This profile is best suited for track or autocross style setups. The peak lift of 11.0mm intake and exhaust will require upgraded valve springs and a titanium retainer. It is suggested to run the GSC5041 Ti retainer spring kit..

The profile will work fine on the OEM rocker arm and the zero-tick lifter, or with the OEM lifter. 

**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 Powe Division billet 7008S2 cams for the Mitsubishi Evo 4-8 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.GSC Power Division Evolution S2 Camshafts  Great for 2.0L engines with stock frame turbos revving to 9000 RPMs or for stroker motors revving to 8000 RPMs. The S2 cams are suggested to run on our upgraded beehive valve spring replacement or full beehive valve spring kit with Titanium retainer. GSC Power Division Evolution S2 Camshafts

• Designed for a rev range of 4000-9000 RPMs (2.0L or 3000-8000 2.2L+)
• 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**

• 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

GSC Power Division Stroker R2 Camshafts The 7008R2 is a high lift, very aggressive profile, with a short overall duration to keep a lower usable RPM band. The 7008R2 is designed to rev between 4000-8500 RPMs and should be used with a stroked engine or added displacement engine. The peak lift of 12.0mm intake and 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.

**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 S3 cams for the Evo 4-8 4G63 are meant for 800+ WHP to take advantage of a very large turbo. These are NOT suggested for anyone running smaller than the 67mm to GT42R turbo.

**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**
