You already have the 16g right? I'm going to assume you at least have an exhaust on it too.

What I would get for $1000

ebay FMIC, or evo8 if you're supa-cheap $300 mounted ($200 evo
nice j-pipe $75
walbro 255 regular, not hi-pressure $75
650/680 injectors unless you have dsmlink then Id get at least 8-900ish. $250
1g BOV $60
intake pipe +cone filter adapter $100
nice MBC $75
used SAFC2 $150
logger $50
18lbs of boost $free!!

$1135 total

Ok so I went a little over 1k but those are pretty much the bolt-ons you would want to start with. BTW I put logger last but it is definately not the least important!
