suby question

ummm....just buy a GT Spec Header & Up-pipe for a WRX/STi. It'll bolt right on. While you're at it get the TurboXS downpipe as well. Then buy my stock turbo from my car and you're pretty much set (TD04E is the turbo). Well, don't forget a boost controller, SAFC and gauges.

Injectors I'm not sure about. The WRX uses top feed injectors and the STi uses side feed. Other than that, the 2.5 block (not internals) is the same as the one found on an STi. Not 100% sure about suspension pieces either.

headers are a must. instant/cheap power.

Probably. I'd imagine that the ECU is almost as smart as the one in the WRX/STi and therefore it will try and untune itself for whatever you do to it. The biggest problem in the past (pre-US WRX release) was getting headers/uppipes/downpipes. Oh, you'll also probably need a turbo inlet pipe as well, I'm thinking of moving to a perrin one so my stock one may be available should you need that, then you can run any CAI designed for a WRX/STi.

www.nasioc.com and read, read, read, then read some more. Awesome information source. Lots of people on there have already done what you are proposing. Just search like a mofo and then ask questions. Sweet choice in the car by the way, love the 2000 and 2001 2.5 RS, cool looking cars.
