My friend has a 96 integra with a B18b1 swap in it. Whoever did the swap, didn't hook up the crank angle sensor and now he is throwing that code. He said that it was a OBD1 motor, but I thought B18b1 was OBD2?

Am I correct or did they make B18b1 OBD1 as well?

94-95 rs.ls.gs obd1

yc_dc4mar

but that motor should be obd2. especially if you know what code it threw

Oh ok.. so they did make an B18b1 OBD1.

Why should it be OBD2? It's running an OBD2 ECU and the distributor is OBD2 (i think, OBD2 Distributor has 1 big grey plug right?)

well im not too sure about that. are you sure the motor is b18a? bec if you threw the code for crank position sensor then it should be obd2...the guy just might not have known.

just read what you just wrote. idk too much about how to tell by looking at it. but as far as im concerned b18b1's are obd2 and you can tell what the check engine light is if its obd2. obd1 you just know something is wrong but not what exactly.

92integraVTECgsr

Well it is stamped B18b1 on the block. So I don't know.

If it is OBD2, than that means that I should be able to hook up a crank angle sensor to the oil pump.

obd 1 hondas are years 92-95, 96+ are all obd 2. secondly, 90-93 acura integras and some early 94's have b18a1. most 94's and all 95's integras have b18b1's. Crank sensors i think are only found on obd2 motors and since your friends car is 96 then that would classify it as OBD2

Ok, here's the definitive answer. and i know this, because i had a guy sell me a 2000 block that was really a '94.

here's how you can easily tell an obd1 b18b1 from an obd2 b18b1.

obd1: valve cover with ridges in it that look like they correspond with the spark plugs.
obd2: valve cover with no ridges.

obd1: no VIN number on block.
obd2: JDM motor, not sure, but USDM motor has a VIN # on the bottom of the block, near oil pan.

On the head of all b18b1 motors, there is a year stamped on it right next to the intake or
exhaust ports. There will be 4 circles with numbers in them. they will look like this:

( 0/8 ) ( 9/4 ) ( 6/0 ) ( 4/ )
^----- whatever looks like a year.. is the year of the block.

Also, older motors tend to have really cruddy valve covers, ie, the black paint stuff has chipped off.

thanks, sounds good.. I am pretty sure it is an OBD2 Motor as well. I'm going to pull the wheel, and timing belt cover off and check the Oil pump to see.

So will an obd2 block work with an obd1 head? Is there a way to bypass the crank angle sensor on the obd2 motor so it wont throw a code on an obd1 harness? Just wondering because I just recently blew my obd1 longblock (boosted 95 LS, cracked the #2 sleeve), and was looking at an obd2 LS longblock (97 LS), but I wont buy it if I cant bypass the crank angle sensor without throwing a code. I wanna use my 95 head on the 97 block.

92integraVTECgsr

what ecu will you be using? if you are running an obd1 ecu, than it doesn't matter.

use a obd1 dizzy and you wont have a problem, i have a 2000 b18b in my 95 and i dont have it CAS hooked up, i beleive obd1 has one in the dizzy

Where is the CAS located on the obd2 motors?

92integraVTECgsr

obd2 on the oil pump.
obd1 in the distributor.

If you are using an OBD1 ECU and OBD1 Distributor, you would have a problem.

projectTeG

b18b1 ran from 94-01, so its obd1 and obd2

So basically, if i buy this motor, I will need an OBD2 ECU also, correct? What about the harness? Sorry for the thread jack, but my OBD1 ECU is chipped and socketed, wouldnt wanna get another one chipped for boost. I just wanted to know if there was a way to bypass the CAS and keep my original stuff. And this OBD2 motor Im lookin at doesnt come with a harness.

i have a 95 b18b1 ls and mines obd1

B18CUL8R

you guys are hilarious.....if you dont know what you are talking about...please refrain from posting

94-95 years = obd1
96-98 years = obd2a
99-01 years = obd2

remember what years these engines were made. b18b started in 94 and b18a started in 90. to tell what b18b you have the number under the "b18b" will tell you.

basically you can tell the year by the number under the engine code. for example a b18c1 with a 5,xxx,xxx block number = the 5 in 5,xxx,xxx indicates the year of the engine. b18c1 started in 94, so a 94 would be 1,xxx,xxx series. 95 would be 2,xxx,xxx series and so forth....for this example motor, a 5 would be a 99 engine

like someone stated earlier, you can get the year off the head too. above the header you should see some numbers like (9/4) or soemthing. if you see (9/4) that means it was produced in 94'

it doesnt necessarily matter what obd the engine is if you are swapping. all you need to remember is to use the corresponding distributor to what engine wire harness you have or you can have a conversion harness if you dont have the right distributor and it will fix that.

you can also find out by vin numbers if they are still on the block and if you work at acura/honda you can just run the numbers through the system and it will tell you where the car came from, what year, what emission type, and what transmission it had.

Bingo, THAT was the answer I was looking for. I know all about all the years of the obd engines, but this is what confused me right here...

THATS why I didnt wanna fool with the OBD2 motor from the 97 LS a guy has for sale. My car is OBD1 (95 LS) and my ECU is chipped for boost, but if I CAN use my ECU, dizzy and existing wiring harness with this motor without having to deal with the CAS, then I'll go for it.

yeah, OBD2 distributor has a big gray plug.
