your best bet is to go to honda-tech.com and just read. hondas are really simple once you get the hang of it. if you are seeking performance you are going to hate the motor that is in the car, i personally would swap to a b-series or k-series if you have the extra cash. cx is the second to lightest eg hatch, a vx beats it out by a couple pounds. but you have got a really good platform to start on. a b-series will make you pretty quick and is for the most part a direct replacemen for your SOHC you have now.
