If you were serious about getting one, I would do a turbo-back exhaust, chip it, and call it a day. Look up a company called Cobb Tuning. More people will be able to give you technical details about them, there are plenty of bugeye owners here. One major issue with them is the transmissions. If you don't beat on it you will be okay, but one of my friends has had one since new and he's on his third tranny.
