For a self described noob? It might be a little more than you want to tackle.
I've seen a few 1.8 motors with turbos. They're cool but still a lot of work, and the most PSI I'd probably push in it would be 5 or 7 pounds before I'd be worried about breaking something. It would definitely be a labor of love because in the end you wouldn't be breaking any land speed records with it.
Dropping a 2.0T from a WRX is a wiring nightmare that I wouldn't feel comfortable messing with. Some guys are wiring gurus and are fine merging harnesses or even swapping the whole she-bang ( and I mean everything down to the tail lights), but I'm not one of them. I've seen a lot of Subies for sale that are halfway through a turbo swap because the enormity of it all became too much for the owners to wrap their heads around.
If you want more oomph, drop in a 2.2. Then you can have fun with some extra HP while you really research what it would take to put a turbo motor in there the right way. :-)
