The wiring isnt that much harder when putting an obd1 motor into your 96. Basically, all you have to do is cut the wires(4 of them) that go to the crankshaft sensors, and re-route them up to your distributor. Plus add a jumper harness to run an obd1 ecu. Other than the normal wiring for vtec, iabs', thats it for wiring, unless you run an internal coil dizzy, than you need to modify for that also.
If you live in a place where your car needs to be emissioned, you will run into problems. As far as I know, you can only use a 1996 p13(because the 5th gen prelude ecu has an immobilizer in it), which are hard to get, and expensive to buy new. My car is due for emissions next month, and even though I happen to have 2 of the 96 p13s', Im still debating whether I really want to have to change everything out in order to be obd2 compliant. Good luck with whatever you decide.
And the jump from an f22 to a jdm h22 (with the proper tranny), is a big upgrade, it feels like a totally differant car.
