You could modify the Focus Jackson Racing SC but at barely 150 whp I wouldn't go for it for how much they want and how much you'd have to modify it. The actual supercharger is too small on that unit to get much more than 9-10psi and it has no TQ.

You might have more luck with the new Vortech, but again, don't know how much you'd have to mod it. For my money it'd be easier to do a custom turbo than supercharger. I did it and I have a returnless fuel system.
