I answered your other question in the fiesta section, for a maram shaft turbo your looking at around £1000 if not slightly more, then the management upto £1000 and you still need to sort out all the other bits and bobs you asked about earlier..... this could become a costly project for you, so why not invest the money in a cosworth for a track car, as its a fast car to start with and the overall tuning potential is greater than a fiesta.
