How hard is a 2.3T to rebuild

I think a 2.3 is a good engine to rebuild for your first because they are simple. I'm rebuilding a turbo engine to put into my Turbo Coupe and it's the first engine I've ever rebuilt too. If you haven't started tearing the engine down yet, make sure that when you do, you keep parts in labeled bags. I'm so glad I did that from the start because some of that stuff I wouldn't remember where it went otherwise, especially bolts and hardware like that. Make sure you have a good place to work, too. I built a workbench out of some 2x4's and a piece of plywood specifically for this engine project.

I don't know of any literature, but a good place for rebuild kits is Northern Auto Parts. Just don't expect to use the pistons from one of their Master kits because they come with hypereutectic pistons, not forged ones.
