are you wondering what power you can get from a turbo upgrade on the stock block? or an intercooler upgrade? or both? that would depend on the turbo, the intercooler, the tuning (chips, etc.), the wastegate, etc. etc. there are so many variables in your question i'm not surprised nobody responded. reliable power at the wheels with a stock block can range from 250whp to 400whp. there's even one guy in vegas who's making over 500whp in a daily driven reliable 951. it really comes down to how much money you're willing to spend.

another question with too many variables. injectors, wastegate, and tuning are a few of the things that can affect how much boost you can run reliably. numbers can range from 15psi to 25psi. most people who experience this problem usually just cranked up the boost without changing anything else, which is one of the most idiotic things you can do to any boosted car.

this question has been discussed, dissected, and answered many times, try searching.
you will find way more information than you'd need.

most people don't replace pistons and rings with an 'overhaul'. the only reasons i've heard are either because something broke, or because they're going to a bigger bore motor (2.8 liter mod). these are available as a package from places like lindseyracing, powerhaus, etc. which you can also do some searching for.
