REMARKS :
REMARKS :
#
Camshafts for use in the Megane II turbo 230hp engine.
This engine uses non-VVT camshafts on both intake and exhaust (as in the standard configuration)!
#
There is a centerline offset between each 1st and 2nd valve, resulting in a different lift at TDC:
-
1st intake valve: 118°
-
2nd intake valve: 122°
-
1st exhaust valve: 113°
-
2nd exhaust valve: 109°
Please make sure there is enough distance between valve and piston at the most critical valves.

ECU reprogramming required
