96, or 97 celica?, Any difference? Options

This has been posted on other celica sites but they all say to come here..:
First off, I want to know what you all think of a '96-97 celica that would be fixed up. I also want to know the limits of horsepower, torque, etc..you can push on the stock engine, and is it difficult to modify or add a turbo onto the engine?
Last question, If i wanted to supercharge it, would i use a centerfugal or positive displacement supercharger?

Thanks in advance,
AC
