To make a long story short, i am swaping a b18a in my eg coupe. I was on planning on a b18b swap but now i am receiving a b18a anyways

Here was what i bought so far:
94+ ls teg shift linkage
94+ Ls teg Wiring harness
5 mount and rubber from itr

I was wondering if i could still use these. I know the shift linkage will work. However, I am not sure if the wiring harness since the b18a is obd0 but my car is obd1. Distributor??ECU??Mounts...etc?? If you guy have done this or have the knowledge, tell your story. Help me out guys. Thanks in advance

Instead of a 90-91 b18a, Would it be better if i buy a 92-93 b18a so it will obd1 and won't have to worry wiring? HUmmm...imput?

Also i m going to get a hydro tranny so the cable hydro conversion is not needed

The Integra engine harness will work but it's not necessary because you can use your stock harness. The shift linkage will work with any B series hydro tranny. The mounts don't have to be ITR mounts, any 94-01 Integra mounts would work. You only need:
Driver's side engine mount bracket and mount
Rear engine mount bracket
Front tranny mount bracket
A/C mount bracket for stabilizer or Del Sol VTEC bracket to reatin A/C
Stock or Integra upper tranny mount

If you are getting it complete with the distributor, injectors and ECU then you would be better off with a 92-93 OBDI motor. If you are getting a basic longblock without the accessories then get the best one for the best deal no matter what the year is, but definitely use OBDI components.

HEy, thanks for the info VTECVillain....

It seem like i m getting a b18a from a 91 ls after all. I m getting a complete swap but i need to know what to change with the obd0 to a obd1 car issue. I think i need an obd1 distributor (but which one?). Do I need to change the injector like you said?? What else??...any info will be greatly appreciated!!!
Thanks in advance

I know that i have to use a 90-91 axles and immediate shaft, a pr4 ecu from a ls, 94+ls wiring harness and shift linkage from a 94+ (have a hydro tranny so don't need cable conversion kit)

VTECVillain

You'll need an OBDI ECU, distributor and injectors. Reuse your stock harness or 94-95 LS if you already have one. There's no since in wasting $ on an LS harness since your stock one will work just the same.

You will want to use 94+ Integra axles and intermediate shaft since you are using the hydro tranny. The 90-93 parts will work but you need to change the tranny seal for the intermediate shaft to a 90-93 seal or it will leak and not fit correctly.

ProJectCvic

Why would the injectors be an issue. Can you elaborate on this for me please...

Yea..so if i use the 94+ axles and intermediate it should be right without leaking a everything right?

VTECVillain

The injectors aren't an issue. It's just that the plug styles are different between OBDI and OBDII. I just said to use some OBDI injectors so you won't have to splice plugs.

Yes, if you use the 94+ intermediate shaft and axles you will be good to go.

I'd like to know about this too. I have a 95 cx and am putting in an ls motor from a 95ls. My friend totalled his gsr, so he bought an ls, and we're swapping the gsr into the ls, and the ls into my eg. I can take any part I need, but I believe all I will need is the mounts and linkage. Any wiring neccessary?

VTECVillain

You'll need to rewire to a 4 wire O2 sensor if you plan to use the LS ECU which I would. Grab the mounts, shift linkage, complete motor and tranny of couse and any other goodies you can get as well.

Ah, wasn't thinking about that. Thanks bro.

ProJectCvic

It's a great day when your questions are answer with acutal answers not just "do some researchs" which I did. Thanks Villain.

Hey I have a obd1 car and am using an Ls ecu obd1 ecu and harness...does that mean that I have to change the injector into an obd1 b/c of fitting? The obdo b18a injector won't fit the wiring harness?

If that is that case than i believe my 93 civic dx injector will work..correct me if i m wrong

Correct, just use your stock DX injectors.

smokey2.0

villan, what changes to the stock dx harness are needed to make it work with the b18 swap! TIA

VTECVillain

As long as you use an OBDI distributor, injectors and ECU, using the stock DX engine harness will make the swap plug and play with not additional wiring.

95hbMatt

Which seal are you referring to??
#18 pictured here?


or #26?

VTECVillain

It's the #18 seal but for the opposite side of the gear box. That picture is the passenger side, you need the driver's side seal where the intermediate shaft goes in. They are probably the same seal for both sides but I would check before you buy.

thankx for the help!

<---feel like an idiot, bought the ls wiring prior to knowing this

Instead of a 90-91 b18a, Would it be better if i buy a 92-93 b18a so it will obd1 and won't have to worry wiring? HUmmm...imput?

THe wiring wont be as hard, but it will still take time.
plus with the 92-93 b18a you have more stock hp, like 10.

I already bought the ls harnes so i m going to use it if i can...my loss
Ok, but i have another dilemma. I have a question about ECU setup. Can i use my stock civic dx ECU with the b18a swap with the ls wiring harness? Or should i use both the stock harness and reuse the stock ECU. I am using the obd1 injector and distributor. I am not sure about this? I believe i have to use a pr4 from a 94-95 LS integra but just wondering if the stock will work also.

ProJectCvic

anyone?

Your stock ECU should work because your still using OBD1, but It would run better with the LS ECU

i would recomend that you run the pr4(or obd1 equivalent ecu), since this is the ecu designed to run this particular engine!
