haha thats everything that's on my list right now, and I'm sure I'm still forgetting a ton of stuff. Dont ever let anyone give you a list of like 5 things and tell you "thats all you'll need."
As far as an intercooler, I'd say it's definetly necessary. If you have to cheap out, then just get some bogus side mount or something- but get SOMETHING. I really dont feel like cooling is a place where you should skimp in a turbo setup..
If you dont know where IC piping comes from and goes to on a turbo setup, then you definetly have a LOT to learn - and probably shouldnt be buying parts yet. Go to
http://www.howstuffworks.com and read the section on turbochargers, read this forum and for gods sake buy corky bell's book "Maximum Boost."
