Well said Amanda. Take her advice, and my experience, the pinstripe stays even after you take it off. I'm putting another on once I repaint mine. You definately wanna find out all you can before doing any work. I suggest building up the internals before booting because the engine will be able to stand higher boot and last longer if done correctly. So far as the exhaust goes, 2.5" or 3" is good. I'm putting 2.5" on mine as my next thing I do to my car.2qu1k4u said:being the car is older, if you take the pinstripe off, you'll clearly have a line of unfaded paint down the side where it used to be.
As far as the tech questions, search around and study up on the car 110% before even touching the engine. howstuffworks.com will help you out on a lot of it.. and i'd recommend reading everything on there pretaining to the car before even thinking about a turbo kit. 2.5" exhaust is alright of n/a, but most people go 3" with turbo applications. kteller.com would be a good place to look around at for those.
all things said and done... search.
