Evo 4-8 - GSC - Billet R2 Stroker Camshafts

GSC Billet R2 Stroker Camshafts. 4G63, Evo 4 to 8

A stroker 4G63 is not just a bigger version of the same engine: the extra stroke changes piston speed and the way the cylinder fills, so a cam profile that suits a standard 2.0 is no longer the right answer. The R2 is GSC's billet grind aimed specifically at those builds, which is what separates it from the S profiles sold for standard-stroke engines. If your bottom end has been stroked, start here rather than working down the S range.

• Billet camshafts ground for stroker 4G63 builds
• GSC R2 profile
• Evo 4 to 7 need the Evo 8 cam trigger wheel and bolt, or their existing trigger wheel modified to take the larger bolt

Fits:

• Mitsubishi Lancer Evolution IV, V and VI (CN9A/CP9A, 1996–2001)
• Mitsubishi Lancer Evolution VII and VIII (CT9A, 2001–2005)
