Here's a generic build list for a 16G:
- Turbo core: $100 shipped to BNR
- 16G: $725
- CNT Catted Downpipe: $300
- STI catless UP: $75
- New Gaskets: $75
- Bullet-proof TMIC kit ($77)
- DW65c: $150
- Protune: $500
That puts you right at your budget ($2002) and is probably the most cost effective / bang for your buck setup.
I over-estimated on the Protune. If you go with an E-tune you could possibly pick up some injectors used of the forum here and still be within your budget.
EDIT: others have mentioned some good points--EBCS (not required but would certainly be nice) and upgraded oil lines for the BNR warranty.
