Since this seems to be a common question, I figuired I'd start a new thread with a comprehensive list. This applies specifically to a USDM WRX -> USDM 1st gen Impreza, but should give you a very good idea of whats involved with swapping just about anything else.
Here's what you need:
-Motor (Complete, intake and exhaust manifolds, IC, turbo, etc-obvious stuff )
-Crossmember (You can use the USDM WRX or STi X-member, but you will have to shim your control arms. The only direct bolt-on x-members are the true GC8 ones and the USDM Legacy turbo ones)
-Front Sway Bar (USDM WRX wagon if you're using a WRX or STi x-member, Legacy turbo or true GC8 bar if you're using the respective x-members)
-Full Exhaust (anything for a USDM WRX should work, some fit better than others)
-Fuel Pump (Need at least a USDM WRX, I'd recommend a Walboro 255lph unit, because you'll probably need more fuel eventually :devil: )
-Fuel Pump Controller
-Full Wiring Harness (This is everything from the harness on the intake manifold to the connectors for the o2 sensors, MAF, ECU, etc, to the plug in the rear harness for the fuel pump controller)
-WRX MAF sensor
-WRX o2 sensors
-WRX ECM
-WRX Powersteering assembly (You need the pump, remote reservoir, and the lines that connect this to the steering rack)
-WRX throttle cable (You need this for a perfect fit if you're swapping a car that was not DOHC from the factory)
-Clutch (If you're re-using your factory NA transmission, you will need to re-use your NA flywheel as well, and get an upgraded NA clutch. I'd recommend a ACT or Spec clutch, I've heard good things about the AST ones too)
-Boost Control (Simplest is the factory boost solenoid w/ ristrictor pill, but if you plan on using certain aftermarket ECU management tools, like the UTEC, you can use the GM factory boost solenoid. It's a 3-way device found on the Typhoon and other forced GM vehichles.)
And thats about it... I am working on a full-writeup that I will post someday but that's it for now. Figuire on spending $2,500-$4,000 in parts. If you can't do the install yourself, factor in about $1,500-$3,000 in labor, depending on who you bring your car to.

For people that need a DBW pedal, the OEM part # is 36020AE130, cost is about $10
