| First off, you can't "turn the cam faster"... it will always turn exactly half the speed of the crankshaft! You may have higher lift... longer duration or you can advance or retard the cam timing. And as for increasing your redline... not real smart considering the valve train on the ETA connot handle it and above 5500 you start to float the valves as the springs can't keep up. If you wan't more HP and a bit sportier mill... just put a 2.5l M20 in it... for that matter if your going to go to that much trouble, just find a m52 or an S52 and do it up right. ETA= low end torque, longevity, excellent fuel mileage, and ease of drivability. Not meant to be sporty. |
