Your friends are typical 17 year olds. Rise above them! Find someone to guide you. Father, uncle, etc. Pulling a motor/trans at the junkyard isn't that difficult. Prepare for it and bring tools (metric), hammers, prybars, cordless sawzall is good. Lots of water and one of those cheap pop-up shelters to provide shade if you can. I'm in Santa Rosa, I know how hot American Canyon can get in the summertime!
OK, just saw your newest post.
Have your reliable friend pull the engine and trans together. You can sell the trans for 3 times what you pay for it at the 'yard. Get everything PNP will let you take for the complete engine. Make sure he gets the VAM (Vane Air Meter) and also the electrical connector for it with about 6" of wire so you can splice into your harness. Definitely grab the ECU. It should say LA3 on it. As stated, the rearend and front spindles should be grabbed too. Once you see how quick the car will be with a 2.3T, you'll want to upgrade the suspension and brakes. You'll absolutely love the 4 wheel disc brakes! Your friend needs to move fast. Once word gets out, it'll be stripped in no time!
This will help you with the wiring.....
The 2.3T is basically a bolt in with very minor fabrication. The motors are normally bulletproof. You can do this!
