I would just buy a complete turbo kit for your car. PSI-FI's or AGP Turbo's kit will do. They come with almost all the needed upgrades, (fuel upgrades, BOV, WG, fuel management, piping, turbo, manifold, O2 housing, mounts, etc...)

About $3800 for the complete kit from PSI-FI.
Stage 1 ECU will run you about $330
Intercooler can be from $600 up to $1200 Depending on what ya get. I personally bought the PSI-FI intercooler.

Good luck!
