If you do a search on this site you should find damn near all the info you need. I wouldn't worry about a bigger turbo and that fancy naaaws right now. Do some research right here in this forum and don't be afraid to ask questions. THe easiest way to learn is to mod what you have now. Then once you get comfortable with everything THEN start going for the big guns. So, your real first mod should be a boost guage, a knock detector, and some sort of a/f guage. A tach wouldn't hurt either. You can get away with cheap autoguage stuff for the tach and boost guage. A 20lb. guage with vac reading will be sufficient
