Are you asking if a supercharger from a 2003 cobra bolts right on to your 2001 GT (4.6L 2V)?01GT said:
If that's the case, the answer would be no.
With a lot of custom fabrication (a whole new manifold) you could probabely make it work, but does it make a lot of sense? If you don't have all the manufacturing possibilities, your best bet would be to stick with a proven SC kit.
Most of them are reliable and pretty easy to install.
