how difficult wpuld it be to put a 81 TURBO engine in a 70 z, i've got 2 81's both turbos for parts both need little work to run. IF I NEED A WIRING HARNESS WOULD IT BE BETTER TO BUY ONE OR ARE THEY REASONABLY EASY TO REMOVE FROM THE DONOR Z
If you are going to keep the injection system stock, just take the harness out of the donor car.
-or-
You can get some sort of stand-alone fuel delivery system/ignition system.
Much easier to take the wiring from the donor car.
