Oil level has nothing to do with the lift and duration of the cams at a given RPM.

On another note, the S2S2's like an engagement between 5600-5900 RPM most of the time.

Get your car on a dyno, and tune it.

after every upgrade your car needs to be tuned!

no tuning = powerloss, no matter how good the parts are

oil level does have to do with vtec...because if you dont get enough oil pressure, then that big lift and long duration of the vtec lobe will not work...

he said that before his vtec was fine, so only if he lost a lot of oil with changing cams this could be the problem. it's tuning
