Im swapping a b20z into a 92 civic hatch dx auto and I have a few questions.

How will the injectors on the b20 work with the obd1 harness? Can I just get something from rywire/phearable/xenocron etc.... because I looked and could only find obd2 to obd1 injector. Could I use a ls intake mani and obd1 injectors?

I have searched part numbers on the upper and lower alternator brackets and I think the upper one differs between a 99si and a 99crv but the bottom is the same.

 

r u converting it to 5speed

 

Yes Im running a 99 si (b16) tranny. Why?

 

Click the link in my signature, What year is the car you are putting the motor into? Typically 94-01 Integra's/CRV's/ and 92-95 Civics SHARE engine side harness plugs (As in regardless of OBD1 or OBD2 'motor' the 96+ B20's harness will plug directly into a 92-95 civic motor bay, no alterations, no custom wiring. *So what I am saying is the factory harness for your B20 should just plug into the main BAY harness in a 92-95 civic instead of trying to do a custom job.

You ARE aware that you will need a special/custom transmission mount correct?

 

Yes Im aware of the auto to manual conversion. The B20 I got didnt come with a harness and the dizzy was cut before and after the plugs which I got another obdII dizzy and will order the conversions for that. I believe everything will plug up besides the dizzy, alternator, and injectors. THe b20 has a unique mani and fuel rail which prohibits me of just throwing some obdI injectors or the whole obdI fuel rail into the b20 mani. Ive tried a b16 mani and it doesnt bolt up. Im still questioning myself on the alternator, I believe I can open up my obdI alt and just plug the whole harness into the obdII alt.
thanks for all the help Oh and its a 92 civic which I stated in my first post.

 

In all honesty, again, It would be easier/cheaper to just buy another B20Z factory OBD2 harness, and call it a day.

The conversion kits for the dizzy alone will cost more than a factory harness.

if you are 'hell bent' on doing it another way, I'd recommend buying a 94-95 B18B1 Intake manifold/rails/injectors (this WILL line-up) B16/B17/B18C series all have different bolt-patterns IIRC for the intake manifolds, the B18A/B and B20 families share the same patterns.

 

Dude the conversion for the dizzy is $35 bucks. I feel you on the harness, in fact I think I have one at home, so I'll check on that. Getting the injectors right will be easy if all i need is the integra mani. WIll both the obdI and ObdII integra mani's work assuming I put the obdI injectors in the obdII mani? Every other sensor seems like it will work fine, theres just 3 things that I named earlier, shouldnt be too hard. I just ordered a 99 si starter, alt, and brackets. Im hoping they'll work. Seems like there would be more info on this swap but I've searched for the past mounth and cant find much.

 

Either mani will work, but if you use an OBD2 one, I assume you will hit the injector clip problem again (Aka I do not know if OBD1 and OBD2 injectors differ in size as far as how they sit in the mani, but I STRONGLY suspect they will work the same.)

 

I think its just that unique B20 manifold. I believe the regular b and d obdII injectors are all the same (besides the clips and orings) except for the b20. So with everything I told you which way do u think I should go?

 

Matter of fact I do have that obdII harness but I think its out of a civic. You think that will work?

 

i believe that 96-98 r the same as 92-95 harness

 

We already know the dizzy, injectors, and probably the alternator are different. Where have you been twisted?

 

looking for other parts for my eg8

 

Well the other harness I had didnt work. The plugs didnt even match and it look liked they belonged on the drivers side.
