Evo 10 - GSC Billet S2 Cams

GSC Billet S2 Camshafts. 4B11, Evo X

The S2 is the step beyond the S1 in GSC's billet range for the 4B11, and it is aimed at an Evo X that has already been given more turbo and more fuel than it left the factory with. The extra duration keeps the head flowing higher into the rev range, which is where a big-turbo X spends most of its time, and it accepts a little less low-rpm sweetness as the price. Plan on a retune to go with it.

• Billet camshafts for the 4B11
• GSC S2 profile, a step above the S1
• Suits an Evolution X already running upgraded boost and fueling

Fits:

• Mitsubishi Lancer Evolution X (CZ4A, 2008–2015)
