Looking for GSC S2 camshafts for 2g dsm 4g63. I am currently on Kelford 264 cams that I paired with a Holset hx35 turbo but I have since changed to an Artec exhaust manifold and Xona Rotor XRC6464s turbo. Need a bigger cam now to pair with the bigger turbo. I am stuck moving 60lbs of air on e85 at 7500-8100 rpms at 30-35psi. Hoping the bigger camshaft will get me closer to the 70lbs of air mark.
