Brian Crower's Stage 2 272 spec camshafts are an all purpose upgrade for the 7-bolt 4G63T.

Each cam is CNC ground to tolerances within .02mm and is prototyped and dyno tested before production. Sold as a matched intake and exhaust set with a cam timing tag.

Why it matters on your Evo 1-3
On a boosted 4G63 the cams set how the engine fills and empties at higher rpm. The Stage 2 272 grind is the sweet spot for a daily driven or lightly modified Evo, adding power without sacrificing drivability or requiring a full valvetrain overhaul. It is the easy first cam step for owners running upgraded turbos, fuel and tuning.
Fitment
