If you have to ask this, you probably should do some more homework.
H + F series + 4G civics = world of pain
If you're serious about doing it, I'd probably:
-convert the car from OBD0 to OBD1
-do a DPFI to MPFI conversion if you needed to
-run the Prelude computer
-make a hybrid harness by combining the stock harness and the prelude harness (you'll need to splice on the prelude distributor plugs, add wires for vtec, knock, vtec pressure ...)
Good luck.
