Got those already. What about internally, is there anything that I won't have to rob a bank to do? I was thinking about autocrossing in a couple of years and I have heard that an n/a might be a little better for that because of the wider powerband. Is the turbo pretty reliable, or is it a pain to mantain? I just want to know what I might be getting into if I go that road. Also, what about the "performance modules" I keep seeing on ebay. Are those bogus or what?
