Decisions.....Turbo, Supercharger, or Phantom ESC???

[why?]

Yea, talk to local shops and local people that have turboed their cars. Sounds like even a zage kit needs modification, so you can probably find someone local that is use to playing with turbos and can make you a kit and install it for less.

Then their are iq boards, there have to be a few crazy iq people that have added forced induction, just see what they did and how they overcame the challenges you mentioned.
