Also if you are thinking about changing cams then it's not the same scenario as other cars. You will need to also look at replacing valves, retainers,colletts etc etc as the 2zz doesn't like it if you don't. Have seen a few who have changed cams and have had some problems with stretching valve stems and the like due to a change of cam with regards to the profile and also the rev range. It's not worth the risk in the long run as it could end up being an expensive repair bill :( Welcome to the forum anyway and hope you enjoy your stay!!
