Plan on swappin in a 92 5.0 into my 81 Capri.  The Capri has a blown 5.0 carby, & C4 tranny in it, the 92 came with a T5, I plan on using the C4.  What will I need from the 92 (wiring, computer)?  Any info that will make this swap easier for me will be greatly appreciated!  

If you want to keep it EFI you will need the computer and harness. Don't forget about 02 sensors gotta have them. Fuel pump and lines. Some how you have to fit the fuel pump into the tank, or swap out the gas tanks somehow. Or you could just swap the intake manifold and leave the carburator. May have to swap oil pans and oil pick up.
