obd wiring help (b18b1)

[inspecta83]

i just wanted to confirm what i've already been told

i am puttin a obd 1 b18b1 motor into my obd 0 crx...i want to know how i'd go about wiring everything up...now, i already know that i can use a obd 0 ecu (i plan on using the jdm ZC), BUT what do i do about making the crx harness plugging together with the engine harness?? i was told that i can just take the obd 0 engine harness off of a crx and slap it on my b18b1 obd 1 motor along w/ an obd 0 distributor. will this work? if so, which engine harness and distributor should i be trying to get over any other?

what obd 0 ECU should i use? i was thinking either the jdm ZC (PM7) or the b18a (PR4)
thanks

since you're not adding a vtec motor, that makes it plug and play on the wiring since you're gonna have the zc ecu. (still might have to add a little more fuel since the B18B is bigger than the zc, just raise the fuel pressure). and like you said, you'll need an obd 0 distributor. the only other thing I can think of is the injectors, those have to work with the ecu (same resistance), you might use the stock crx's injectors with the new motor.

thanks alot for your input, i got the distributor, engine harness, cable tranny and injectors yesterday...now all that i need is the ECU. what do you think? '90-93 integra LS (PR4)? OR the jdm ZC (PM7)? or something else? thanks

also, is it difficult to swap the engine wire harness? anything that i should be aware of when attempting to do it?

I'm not 100% sure on the ecu's, you could always get your stock ecu chipped if the ecu is gonna be hard to find.
