There ain't anyone else than TKT around making "kits" for our car. Besides, even if he sells them as a kit, they need custom work to fit your car. The only right way is to go with custom setup. Have a turboshop working with your car (propably around that kind of money or even more) or make one of your own. That is the way I'm going. Besides, there are tons of other things to consider when moving to forced induction. Main problem in getting enough fuel and you have to upgrade your clutch....
Hope this helps even a bit
