GSC Power-Division billet S2 camshafts for the Toyota Supra 2JZ-GTE. The S2 camshafts are designed for those running a single turbo larger than 71mm.
These camshafts will not have bottom end losses over our S1 cams on the larger turbo; nothing but gains will be seen and will promote great peak power gains. Gains of 60-100 WHP (depending on turbo) have been seen by bolting the S2 cams in, re-shimming, and tuning.
These cams do require upgraded valve springs but can be run on stock, non-ported cylinder heads.
