A Positive Displacement type system like the 2003/04 Mustang Terminator will not fit without EXTENSIVE modifications.
It can be done and over 600 HP is easily achieved. Plan on spend almost enough to buy a 2nd Mangusta:
Depending on how much boost you plan to run, you should replace the pistons and rods with good quality Forged ones so they can hold up the new HP. I'd recommend upgrading the Trans to a Tremec T-56, a Mcloud clutch, return type fuel system. The front Cross member will obstruct the pulley drive system for the supercharger so a new one would need to be fabricated. Additionally the frame will need to be modified to fit the alternator...unless you can place it someplace else.
My advice is to go with a centrifugal type supercharger such as a Paxton or Vortex as that has been fit in with much less modification. Keep the boost fairly mellow and push the HP up to maybe 450 and you won't need to go with a forged rotating assembly.
