the key to N/A tuning is redline + gearing.
there are two things you will need to do.
first, decide exactly how much power you want to make, and wether you want to raise your stock redline or not.
once you decide that, you need to formualte your plan of attack.
here are my suggestions, assuming you are okay with raising your stock redline, and are looking to gain about 25-35 real whp while getting yourself deep into the 14's
personally, i would not go with anything less than a stage 2 sort of cam. the crower 402's now come in a 402A, which has the stock non-VTEC cam lobe profiles and the usual 402 VTEC lobe- so you wouldn't loose any idle quality at all, and still have decent top end grunt. You should be able to make power up to 8500rpm with those cams, maybe beyond. Obviously to raise the redline you will need new springs/retainers etc. and standalone engine management. Some mile head work wouldn't hurt either. A thinner head gasket to bump the compression a few tenths of a point is also highly adviseable, maybe even milling the head or new pistons, but with a set of 402 cams, you really won't need that huge of a CR bump - let your tuner decide if you are unsure of what to do yourself.
once you've EFFECTIVELY raised the redline (that is extended the peak rpm at which you make power), to fully take advantage of it, you want to change your gear ratios. I'd suggest an ATS 4.79 final drive and a gs-r or LS fifth gear to keep your highway rpms decent.
also, i'd reccomend you ditch the DC headers. in favor of the JDM itr 4-1, or the comptech ITR 4-2-1. That DC header is fine until you start moving massive amounts of air.
N/A buildup is NOT a simple bolton effort, it requires planning and more planning. and it's expensive.
but good luck.
