Pat, take it from someone who's been around a bit. You don't need a turbo. Not if you're 16 and it's your first car. God this sounds condescending, but in all honesty, you'd be a hell of a lot better off if you built a neat solid 4K. You wouldn't have issue of lunching pistons, using second hand parts (definitely NOT recommended), and you would have a good solid car to drive that wouldn't give you any grief. You don't need that sort of hassle in your daily driver.
I apologise if it's not your first car, and I'm over generalising, but I stand by the statement....
