Re: Camshafts for the EG33.

The problem with the lift with hyd followers, is that the valves are too short, so that the spring binds at 9mm. Using solids and the longer WRX valves lets us use a longer spring, and higher lifts.

Hyd lifters are too heavy for high rpms. Have to use stronger springs to follow the cams, this causes cam/follow wear, and can end up pulling the head off the valve.

The lightest valve gear, is needed for high lift with short durations.
