do a custom jobbie. goto a sports garage or something and ask them if they could help you develop a Supercharger or Turbocharger. I am sure MANY people on this board alone would be VERY interested. I would be, for one.
Finding a turbo and strapping it on is not the problem. Its in the timing and fuel delivery. You could (thereoretically) throw any old turbo on any car (I'm exaggerating a bit here...) but you still need to re-work the computer. You will need a new boost gauge to measure the boost from the blower, and you will need to modify the timing and the fuel delivery in the computer. I'm not sure if any of the performance chip makers can do that either, but if you go to www.aempower.com they develop user-programmible ECUs for cars. If they could make a program for our car, then bingo, you could strap a turbo on with no problem! Its all a matter of $$$
