Product Description

The GSC Power-Division 7032S1 is a set of billet S1 performance camshafts for the Gen 2 Toyota 3S-GTE turbocharged 2.0L engine found in the 1991-1995 MR2 Turbo SW20 and 1989-1993 Celica GT-Four ST185. These camshafts are designed specifically for turbo-upgraded 3S-GTE builds targeting 300 to 450 wheel horsepower, featuring 268° advertised duration on both the intake and exhaust with intake peak lift of 9.60mm and exhaust peak lift of 9.70mm. The cam profiles are optimized for strong mid-range torque and boost response that are well-suited to street/strip and spirited driving applications without sacrificing daily drivability at moderate power levels.

Each camshaft is forged from solid billet bar stock and CNC ground on one of the most advanced grinding machines in the world, ensuring precise lobe profiles, tight tolerances, and exceptional durability under the extreme conditions of turbocharged sport compact engines. GSC Power-Division was founded in 2004 to fill the need for high-quality performance camshafts and valvetrain components for Japanese sport compact platforms, and has since become a worldwide supplier trusted by professional engine builders and race teams. These cams are designed for the Gen 2 3S-GTE's shim-over-bucket valvetrain -- valve shim clearances must be re-measured and adjusted after installation by a qualified technician. Not CARB approved -- intended for off-road use only. Designed and manufactured at GSC's facility in North Charleston, South Carolina, USA. Backed by GSC's 1-year warranty to the original purchaser when installed by a certified SAE technician or engine builder.
