Default 04 STI engine -> 02 WRX questions

What I have: 02 WRX with an 04 WRX Tranny
What I have to Install: Complete (everything under the hood) 04 STI engine with ECU, engine bay wiring, control arms and x-member.
What I want to end up with: a fun ass DD.

My Questions:
1. What will I need to mate the 04 STI engine to my 04 WRX tranny?
2. I believe I will need a V7 JDM STI ECU, is this correct?
3. What else do I need?

When I go away to Basic Training in 4 months, my brother and Father are going to install this for me for a cool $500 + a couple of remodeling weekends at my parent's house.

Thx, Dan

Sounds like your on the right track, many people have answered this on Nasioc, Do some searching and return to this thread

1. Engine Should Be a Direct Bolt-on, If you can Get a stronger tranny than your 02 WRX those trannies are known to be ****

2. You will need the entire harness that goes with that car

3. Searching will answer this.
