I just bought a 2000 civic ex cylinder head, intake manifold. Up for changes is the camshaft. Is the zex stage 2 cam the best for the buck?

on the intake manifold has a throttle rotor looking thing, tried to find it on my haynes, but no avail of what it is, what it does, ist it really needed, how or what is needed to make it work.

A customs shop told me that there are no need of cam bearings, how is it possible? How much will it cost and how many is needed. The cam seal(s) is hard to find also. thanks

 

there are no cam bearings

 

It sounds like the rotor you are talking about is for the throttle cable. If you don't install the cable you can't drive the car. The rotor is what opens the throttle valve. As far as cams you could have Delta do a regrind on the one you have for the 00 head, they have specs for most of the popular cam manufactoring co. I believe they are like $100.00 shipped if you send your's in to them.
