S2 Camshaft Kit for VVTI 2JZ-GE

The GSC Power-Division Billet S2 Camshaft Kit is engineered for the VVTI Toyota 2JZ-GE engine, specifically targeting high-output builds. These are the only forged billet core VVTi Camshafts available on the market. The S2 profile is optimized for vehicles equipped with large single turbochargers, generally those exceeding 71mm in size. This camshaft set is designed to prevent bottom-end power losses often associated with larger turbo setups when compared to S1 cams. Featuring a rev range of 4000-8500 RPMs, these camshafts are capable of supporting 800-1500 WHP. Installation of the S2 cams, along with reshimming, has been reported to yield gains of 60-100 WHP, depending on the turbocharger setup. Please note that these performance camshafts will result in a rougher idle compared to stock. Key specifications include an intake duration of 274 degrees and an exhaust duration of 274 degrees. The S2 Camshaft Kit requires upgraded valve springs for proper operation and is designed for the 1993-2002 Toyota Supra. Installation of performance camshafts should be performed by an experienced, SAE-certified mechanic or a skilled high-performance engine builder.
