fyi--
Swapping a efi engine into a car with a carburated engine is considerably more diffucult due to the wiring required to get the swap to work. I'm speaking somewhat from experience (helped my bro put a efi 350ci [5.7 liter] engine in his '76 chevelle). There may be a company that sells a wiring kit for honda efi conversion swaps, like how painlesswiring.com sells kits for chevies.
