Ive already searched and found some answers but not really direct answers, need help alot of it
I have a B18A motor from a 92 integra which is OBD1 and i have a 90 integra shell which the wires are obd0
I want to drop the b18a motor into the 90 integra but i noticed
there different OBD's. What do i need to convert it. I know i need
the jumper harness for the ecu. I really need help, let me know i know stuff
but not so much
help me out

Where are all the acura guru's?

 

your dizzy will have to be changed and im pretty sure the manifold is different. i did the exact same thing to my car, but from OBD0 to OBD1. i just switched out the complete manifold and dizzy, had no troubles at all

 

hey your best thing to do man is to change your ecu and get a OBD 1 ecu cuz it would cuz u more work to change the wires to make it fit to an OBD then just to change up your ecu that u have now. to an OBD 1 model. and u get it from any integra up too the year 95 cuz after that it became OBD2

 

If you plan on doing any tuning in the future, it's best to convert the shell to obd1. It's gonna be around 100-120 for the ecu jumper harness, and you can also get a conversion harness for the dizzy. Or, you could just re-wire or re-pin the dizzy for free. I'm pretty sure the alternator plug and injectors are gonna be different too, but it's not that hard to re-wire.

If you want to stay obd0 with the shell, just use the 90-91 ecu and engine harness that was meant for your obd0 car. You might have to extend a couple wires, I can't remember, but it wouldn't be a big deal.

 

yeah like seanbev24 said if you wanna stay obd0 just get a harness and ecu off of a 90-91 teg and a dizzy off of the 90-91 teg as well as the O2 sensor would have to be changed to the single wire that's about it everything else is plug and play

 

Thanks for all the help
Well most likely i was thinking of converting it to OBD1, just by buying the jumper harness and buying the conversion harness for the dizzy.
I do have everything from a 92 integra because it was crashed so i found that 90 shell and just wanted to swap everything, so i already have the ecu and everything from a 92 integra.
any more tips since i just added more information

 

if you have the complete car you "could" swap all the wiring and make that 90 an OBD1 car which would be in your best interest since personally i think obd0 sucks..

if you want an easy fix swap the motor and get a conversion harness...

should be golden then

 

How much trouble is it really taking the wire harness from the actual car and putting it inside the other shell?
Will i have to cut any wires>?

Okay. You won't get anymore direct then this. Like you already said you need the adapter harness wich you can get at rywire.com for $100. Then you also need the OBD1 Dizzy. You will also need the OBD1 ECU. Oh and you can also get the Dizzy conversion harness but you have to call him. Plug your conversion harness into your PR4 (OBD1 ECU), then plug that harness into the existing harness attached to the car. Lol, I'm actualy a little buzzed right now, so I may be a little off, but check out rywire.com man. He gives you complete instructions with his setup. But aside from what I already said there isn't much more. As long as you bought an actual complete motor swap or at least the Dizzy and ECU included, then you should really only wined up spending another $150 at the most

 

Thanks man for the straight up answer. Helped out alot now im not lost lol

 

lol, it's cool man thats what the communities here for. PM me for anything else you might need help with.

 

Lol, will do, thanks again

 

you have no idea how much work is involved in what you just suggested.

 

your better off going obd0,things you will need dizzy,injectors,alt,ecu harness,header w/o2.

 

i already have all of those from an OBD1, since i just took out the motor from a crashed 92 integra and bought a 90 shell, so i have the parts needed

 

The convertion harness will work great for you you should look into that first befor trying to swap all the wires thats gonna be a tough thing to do Not a hard swap though that motor should drop right in fairly easy for you you will have a couple of trouble with the vacume lines if you go with the OBD1 dizzy there are a couple of differences in the two I went from obd2 to obd0 with a b18b1 had to t some vacumes and creat a couple fittings in the intake just follow you hose diagram under both hood and it should help out alot

 

Thanks for more help, im starting tomorrow and ill let you know what happens

 

yeah, deffinately keep us posted. I check on my posts often so it shouldn't take long for a response if you need help with something.
