Default Upgrading a stock 2.0T a4?

First post on this forum, and I figured the dudes here would help me more than others on other websites.. lol.
Deciding on a '05 Supercharged C230 or an '06 Audi A4 2.0T. I had a 1.8T before but only leased it for 3 years so I couldn't mod it out.
IF I do end up purchasing the 2.0T, obviously it's a stock turbo and it won't be much power..
1. Could I swap it for a larger turbo and larger injector, to put out more psi and make it faster in general?
2. What turbos would be compatible and slightly on the cheaper side?
3. How much power would it add?
4. What size injector?
5. How much would it be for installation?
6. And how much HP would I have in the end?

Any other details you're willing to add is greatly appreciated.. Thank you!

Since nobody else is talking to you, may I offer my 2¢?

If you like tinkering with your car, get the Audi. You can go step by step toward more power, depending on your budget. There’s aftermarket stuff out there to get ~ 400 HP out of the stock block. I’d start with an ECU upgrade for about 15-18% power increase depending on whose chip you get.

I just recently bought my B7 6spd and i'm very happy with it so far. It has it's issues but that's what happens when you buy a car second hand, and it's nothing that I can't handle. You'd be plenty happy with the B7 or B8 over a C230 quite simply because of the aftermarket for the Audi's. APR's turbo upgrade should be good for you since they offer a complete kit for the car so you wouldn't have to go around looking for the proper parts. Hope this helps
