I have a 91 CX civic hatchback and a 93 Integra RS motor. What wiring harness/computer do i have to use to get this motor to work in the civic?

 

Are you sure its a cx? Never heard of it. Search I personally have answered this question(b18a into ef) about 6 times in the past month.

cx also know as STD

its base model

it needs mounts mpfi swap axles etc

 

My concern is that the b18a is obd1 and the EF CX is obd0 i guess? I don't know what harness to use, i am sure it's the EF CX harness, but would i have to change the distributor or what?

And yes the car is a '91 CX charcoal grey. I am located in Canada so maybe that's why.

not all b18as are obd1 and you'll have to do wiring can't just bolt a harness up.
read up MPFI swap info and B swap info its all covered

I dig that grey

 

Here is what i've concluded. To do the swap i have to switch the Civic fuel injectors and Oxygen sensor to the b18 motor and get a obd0 '91 and under distributor and ecu from an integra.

Does that sound about right?

 

I don't know why i'd have to do wiring, there is no vtec, knock, pressure, etc to be wired up. I've done swaps in my old EK and EGs b18c1 and b16a2 and b18b1, but never have i dealt with EFs so i just need a very brief run down, the rest is peanuts.

Also will the DA seats fit in the EF? Are the rails swapable?

 

you have dpi you will need mpfi.

your adding 2 injectors so you need to wire

search mpfi swap like i said before

 

yea a 93 b18a1 is obd1, rywire.com has a conversion harness if u wanna go obd1. if the cx is like the dx then u have to change to mpfi, there is a converision harness for that too. you have to use a b18a obd1 distributer if u go obd1. but if your car is mpfi then u can use that harness and keep it obd0 and use a 90-91 b18a ecu and distributor.

88-91=obd0

 

never heard of them called a cx guess you learn something new everyday. but ya everyone has told you the right things to do.
