Power Division S2 Billet Camshafts Mitsubishi 4G63

The GSC Power Division 7008S2 S2 Cams are a pair of billet camshafts engineered for the Mitsubishi Lancer Evolution IV through VIII (4G63 engines). These camshafts are designed for builds aiming for 400-700 WHP and are suitable for use with larger turbochargers without compromising low-end power. They are stated to provide gains of 50-70 WHP over stock configurations. With a duration of 274/274 and a lift of 12.0mm intake and exhaust, these cams are optimized for high-RPM performance. For 2.0L engines, they are designed for a rev range of 4000-9000 RPM, and for 2.2L+ stroker motors, they are suitable for 3000-8000 RPM. The S2 cams can be utilized with the factory ECU, provided it is custom-flashed, and are suggested to be run with GSC's upgraded Beehive valve spring replacement, although they can operate at the stock rev limit and factory boost on stock springs. Installation notes indicate that the idle quality will be rougher than stock. It's important to note that these camshafts are specifically designed for the Evo IV-VIII models; Evo 9 GSC Cams are available separately.
