hehehe, I already see the direction this is going to go...
Based on what you have said I would suggest getting the exhaust done, intake (gutted air box, CAI, FWI, etc.), scan for KR and put in a PLOG (replacement for restrictive front manifold) if neccesary, then drop to a 3.5 - 3.6" pulley and have someone custom tune your ride. That will give you plenty of pep, without any worries. None of these mods should be very hard or expensive if you do a little research and can turn a wrench.
If you're like the rest of us though, your going to get to that point and the mod bug will already have nested deep inside of you... the mod bug is relentless and unforgiving.
