School me!

Once again thanks guys, I am trying to figure out what it is I want to do. I have several different ideas, but in the end I know I want something that is special. There is not an overabundance of older cars that are turbo charged or pro charged. I feel lost when it comes to turbos, starting at the set up to the cost. I feel i know nothing. I have been reading every chance I get to see if its what I want. Thanks for the links.
