You're about two years too late. Dinan just did their last one close to a year ago (they no longer offer it), and I don't think Korman still offers their (much simpler but affordable) turbo kit. Mine was a Callaway turbo (same company that did the factory-option Alfa GTV6 Twin Turbo and factory-option Callaway Corvette) but Callaway sold all the turbo stuff of to New Dimensions, and New Dimensions scrapped everything except the VW application.
Basically, you're better off finding a used Alpina B7 or Dinan 535i/M5 turbo conversion already done. Still will cost you at least $15K - $40K.
