Wiring will be the biggest hassle that I can foresee. Grab copies of the wiring diagrams for both and look for the differences. The SE motor has an electro-mechanical device that pushes the throttle on a little bit when required - I think such as when the car is in gear and when the A/C goes on. Also, I think there is some temperature sensors that adjust the FI when cold. And lastly, you will need to run wires to the fuel pump at the back. The fuel tank may be a little different but that should be ok. Not sure about fuel lines, but as the carbie cars still had a return line you should be ok.
So unless someone hops on with specific experience, you had best pore over some wiring diagrams. I wouldn't be too scared of it though, wiring is reasonably logical. But it may be awkward trying to do the wiring and make it look pretty.
Good luck, Drew
