Are these the right cams for me? GSC Power-Division S1 Cams

These cams are a great option for anyone making, or looking to make up to 750hp on their 2JZ-GTE. They broaden the power curve without losing bottom end power. If you are making over 750hp, or plan on making over 750hp, you should consider stepping up to the S2 cam, which will better utilize that powerband.

GSC Power-Division S1 Camshafts are designed for upgraded turbo setups larger than 57mm. These camshafts are designed to increase air flow at upper RPM without sacrificing low end power. These cams promote a flat and broad torque curve and depending on the turbocharger, have proven to pick up 40-70whp gains. The RPM range that these cams are designed to improve is 3500-8000rpm.

A valvespring upgrade is suggested when using these cams. We offer a single spring upgrade that can be used with the factory retainers, or a full dual spring and retainer kit for high rpm abuse.

The engine idles only slightly rougher than stock with these cams so the car will still be very streetable.
