GSC Stroker R2 Camshafts Billet Mitsubishi EVO 8

• 2003-2005 Mitsubishi | EVO 8

The 2.2-2.4L lower reving engines a profile that would allow for more air volume in the cylinder to help fill the larger displacement engines and make more midrange and top end power. 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 do to valve seal to retainer clearance. The 5041 can be used to 40+psi and the 5040 to 32psi on the R2 profile at 8500rpms 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 25-30whp 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 lenght, some cam gears are too thick for the OEM bolt on the Billet cams, a 40mm underhead lenght bolt may be necessary in this case**
