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 S1 cams for the Toyota Supra 2JZ-GTE. The S1 cams are designed for those running an upgraded single turbo larger than 57mm. These cams will not have bottom end losses over stock cams; nothing but gains and will promote an extremely flat torque curve. Gains of 40-70whp (depending on Turbo) have been seen by simply bolting the S1 cams in and re-shimming. Designed for a rev range of 3500-8000rpms, these cams require a single valve spring upgrade over stock. 450-800whp camshaft set with an idle slightly rougher than stock.
S1 Specs GSC0-7030S1:
- Intake 269 Duration 9.90mm peak lift, 108 degree Centerline
- Exhaust 269 Duration 9.90mm Peak Lift, 114 degree Centerline
