Depends if you've done anything else to the motor. You really should lower the compression for a supercharger either by dishing the pistons or fitting a lower compression set. I would then go carburetor as i'm not into all the electronics shit that goes with injection.
On saying that I am fairly heavily involved with a certain 100E that is supercharged and runs injection with no engine mods at all. Just waiting for the big bang.
When you get into this game it's a case of trial and error. If it works you're lucky if it don't you're skint.

is it a range rover motor ? if so already has low comp pistons (i think)
they do a supercharged rangey so injectors and ecu or whatever exists, so must be do-able
From what little i know the 3.9 motors wont take much extra
