GSC Power-Division Camshafts:
These are the best cams on the market for the 2JZ!! They are fairly aggressive and offer a decent idle lope. We highly recommend a strong upgraded dual valve spring and retainers such as the Supertech or the GSC Beehive springs/retainers with these cams.
GSC Power-Division says:
GSC Power-Division S2 cams for the 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 re-shimming. 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.
