OK guys, I have a 90 crx si with a zc motor that I'm building. I have the block sleeved and bored to 75.5mm and am using eagle rods and endyne roller wave pistons (low compression). I have ARP head studs and Clutch master stage 3 clutch. I'm planning on boosting with a 14b (w/FMI) at around 11-14 psi. I was wondering now that I'm broke , what do I need to do to my head to get as much potential out of it as possible for the cheapest price??? Do you think just PnP, valves and springs would work? maybe cams? If so, which are the best??? Help me PLZ!!! thanks!
