at the very minimum do posting, and a new factory headgasket if you want it to last.
then from there you should do pistons, rods, bearings.
i am gonna build a zc i have laying around but i cant afford all the machine costs right now.

Re:HP Differences Between B20VTEC and B20 NonVTEC?
The RS Ratio is a tad bit intimidating, when I first did my ls/vtec I was kinda worried about reving over 8k but I did it many many many many times, over and over. No problems and it had well over a Hard 10k miles on that engine. The only reason my ls/vtec broke was because I got cocky with the boost at the track, the map was only tuned for 12psi, and I cranked it up to 14 and I still had the stock fuel pump. Right now I have been boosting 12psi on my B20vtec for quite awhile, and it's working just fine. I'm even made a few pulls at 15psi but the clutch is questionable, lol. Stock sleeves are just fine, you just have to be "PERFECTLY TUNED".. what does this mean?.. a perfect AF tuned on a dyno w/ wideband and a very conservitive spark map, meaning not to much timing on the top end. (no detonation) I have no worries in my engine at all. I spin my ------- b20 8400 all day long. Get a vtec oil pump and a main block girdle if you can and your good to go!
