It is VERY common to drop 3800's into the back of Fiero's for a great project car. The engine will be fine with just the harness/pcm/fuse block from the donor car, and the rest of your project is yours to figure out, since it'd be very one-off attempts at integrating those parts.
Look up details on Fiero swaps, and you should be able to see the extent to which wiring is laid out. I might have some pics when I overhauled a setup for someone ~15yrs ago...
BEFORE & AFTER streamlining the necessary wires (manual trans)
