Just me.....I would to a tork tech eaton build. That could easily be done for under 5k....including the extras that you need. If you wanted to splurge....then it would still be under 6k, possibly 400 rwhp and would still be completly streetable.
Start with a Tork Tech Terminator manifold. Search ebay, craigslist, a much of modular forum parts sites (pm me if you want a list of good places to get the stuff) for all the supporting stuff you need.......Cobra Eaton M112 blower (ported one would be nice), injectors, heat exchanger, heat exchanger pump, reservoir, BAP, throttle body, throttle cable, cruise cable, lightning IAT sensor. That is most of the stuff you need, and picking everything up used is the cheapest way to go....and it is a proven setup.
Manifold: 2k
blower: 500 (with throttle body and everything)
injectors: 150
heat exchanger: 300 (frozenboost.com w/ piping and pump)
reservoir: 50 (almost any type of small reservoir will work)
BAP: 150
cables: 100
IAT sensor: 20
Hood: 700 painted
dyno tune 500
CAI: 150
Lightning MAF: 100
This is about 4770....that leaves you 1200 to see how you want to do things. A ported eaton might cost you a little more, then add a bigger throttle body. You can do it for less than I typed, but I just pulled up stuff I could find in less than 5 minutes.
Oh, did I mention the appearance mod of either a cobra hood or a 2.5 or 3.5" cowl hood. Kaenan or HO Fibertrends hood would be perfect......
