I'd love to turbo it but the mk3 options currently available are all on the pricey side (the best kit is the BBR one but its £6k), and I'd need a new clutch too. None of the turbo kits available now are modular or designed for a second hand turbo so its not like you can amass the kit bit by bit either like most people do with the earlier cars. Skuzzle Motorsort in Winchester are doing a modular kit that they hope they can sell for about £3k but its early days yet in terms of development.
BBR are meant to be doing a 200bhp n/a kit for the mk3 too which is almost finished, these parts could be added to what I've got already and would be pretty nice....Blink motorsport are also doing work on a set of parts that should work with my car and hopefully get 200bhp as well...so theres other options for more power even without a turbo. Realistically it'll be another year before I spend any more money on this...so will see how things pan out with all the parts the tuners are working on.
