Not yet, but I'm looking to do my 2000 to a Turbo.
When Rallispec is finished prototyping their turbo kit, I'll see if they can do a custom job on mine. I dunna think I need 14lbs of boost. They're kit has a solid technical basis and the adjustability that I'd be looking for.
I'd like it more for track days, since I've got a company car... it wont get much use otherwise (okay maybe getting groceries and racing the soccer mom minivans...)
GTBGUY, any pics of your setup? What size/internals are you using for it?
