whats sup,i'am not a newbie or a pro with hondas
but i have a 95 civic coupe,with the single cam vtec
looking to swap a 1993 b18b..any help with what i need
will be great...also with the wireing my friend said the b18b from a
93 teg is obdo and will not just plug into the civic
is this true?

 

a 93 is obd 1 and far as i know the b18a1(90-93 i think) is obd0 and the b18b1(94-95 i thk) is obd1

 

oh and by the way i am in the middle of a swap like tht and its not tht easy when ur not buying all the adaptations(i guess u can call it tht) i have a 96 civic dx(obd2)shell.motor- b18a1(obd0)out of 90 integra.wiring harness-same one tht came in the car(96 civic).ECU-P75(obd1)out of 94 integra LS.
and i made the mounts tht i couldnt use(cheaper)but i dnt advise it unless u do it right and take ur time and put a good weld on it. also i pinned everything,splicing isnt the right way to do it(belive it or not)......any specific questions just ask and ill help if i can,if u find anything out about a better set up or were to get ECU pin outs please let me know

 

Here is EXACTLY what you need:
*Engine and tranny(of course lol)
*B series hydro shift linkage
*Gsr/ls rear T bracket
*B series clutch and flywheel
*axles
*obd1 p75 or pr4 ecu (preferrably p75)
*obd1 b series alternator, dizzy, and starter
*B series headers

And that is pretty much it. If you have all that, it bolts DIRECTLY up. No need to redo the wiring or ANYTHING. And stock mounts are fine for it too. And a b18b is not from a 93, its from 94-2001 i believe. 94-95 is obd1, and 96-2001 is obd2. But regardless itll still bolt rite up if you have all the parts listed.

 

The pr4 is the 90 Ls right(for the B18A1)? If it is the ecu hook up is different clips than the p 75...also the 90 integra engine harness for the b18a1 is also integrated with some of the chassis wiring harness

 

oh and dizzy is distributor right

 

There is two pr4's. There is a obd1 pr4 and an obd0. The obd0 is 90-91. And obd1 is 92-93.
And yes, dizzy is distributor

 

lol

 

lets say i have a 94 ex coupe (d16z6) which has a p28 in it couldnt i use that ecu for a bseries swap? n engine harness if the motor is obd1
