Here you go man, maybe this will help you out...
I'm doing a buildup on my motor, going n/a as well...here is what I got everything for, just so you can maybe weigh the costs of n/a vs. blown and decide which is better for you
PI Manifold - 100 off ebay
PI Heads - 300 used off ebay
Comp Cams 102300 - 500 off thunder racing maybe? can't remember
BBK 75mm TB - 230 off Summit
C&L Plenum - 120 off the C&L site
JLT Cold Air Intake - 220 off the JLT site
BBK Shorties - ~300 off summit
Pypes o/r x - free to me via girlfriend, but 150 elsewhere

Cylinder head valve job and porting - 750 from Fastlane Motorsport in NC
Install complete with new head bolts and all new mounting hardware, plus tune and dyno afterwards - 1500
I'm not sure how much power I'll be putting down, but it'll be over 325 i'm sure. The reason that I say this is that I've seen the dyno sheets on my cams, and ported PI heads and they gain around 50 and 80 hp respectively. IDK if this helps you at all, but the total is pretty high, to essentially get close to the same hp you will have with the blower...i'm just stubborn and wanted to be n/a on the 2v. If cost is your goal, then going blown is as well IMO lol
Incase you were wondering the other mods I am having done include a 2500 stall, 3.73's, battery relocation, 315's and a new k-member to hopefully shed a few pounds.
