A perfomance cam for a 2000 honda accord with an f23 in it.

Have you tried entering “perfomance cam 2000 honda accord” into a search engine like yahoo.com or google.com?

Unless this is going to be a full on track car (in which case you didn’t pick the greatest car to start with), it’s not going to be worth it. With camshafts, particularly in small engines, there is no free lunch. You could put a hotter cam in, but whatever you gain in high RPM HP you will lose on the bottom end. When you factor in that Honda engines aren’t known for their torque to begin with, it doesn’t make much sense in car that is going to be used on the street.
