You should really read that some time...it doesn't have any D specific info, but there still is some good info on there.
What do you want to know.....????? Are you doin this build on the stock motor or are you building it? What's your budget?? Power??
Need more info, but if you read that site top to bottom, you should have a lot better understanding of turbo systems. You don't have to read it top to bottom, but skim parts of it at least.....
