GSC Power-Division S2 cams for the VVTI Toyota Supra 2JZ-GTE. The S2 cams are designed for those running a large single turbo, larger than 71mm. These cams will not have bottom end losses over our S1 cams; nothing but gains will be seen and will promote great peak power gains. Gains of 60-100whp (depending on Turbo) have been seen by simply bolting the S2 cams in and reshimming. Designed for a rev range of 4000-8500rpms, these cams require upgraded valve spring, but can be run on stock cylinder heads. 800-1100whp camshaft set with a ruffer than stock idle.
