hey guys i got a b16a in my DA,
need to buy a new distributor so need to know what obd my motor is.
im pretty sure its obd1 but just wanna make sure.
how can i tell? searched around but couldnt seem to find it, so im sure this will help others that search for it..
also, how do i tell if my motor is sir or sir 2?
thanks guys!

 

Prob OBD0... what year is the car? Does it have an obd 0 to obd1? theres lots of factors that it could be anything... its prob a xsi B16

 

i have no idea lol, didnt swap the motor myself.
i have no clue when it comes to this **** lol
its a 92

 

Take a picture of your distributor and it's plugs.

 

if the DOHC is bigger than the VTEC on the valve cover AND the valve cover is the original one, it is an OBD0 engine. otherwise it is OBD1 or later.

The 92 integra is an OBD1 car so I would assume that it is an obd1 engine just because the conversion down to OBD0 or up to OBD2 is not exactly trivial.

Also you might want to look at the year the engine was made on the head of the engine. I know my GSR motor had the year on it.

 

That would be hard to tell if it was the original VC, he doesn't know much about the motor so there is a doubt that he knows if the VC is original.

 

ok then maybe this will help more. Here is a picture. This is a B16A SIR II motor that I put in a civic a while back. if you look at your engine in the same area as is circled on this picture you will see the engine's year ID. You can use that to find out what year it was made. if it is stamped from 91-94 then it should be OBD1. I say 91-94 because most 92 model year engines would be produced in 91 and most 95 model years would be produced in 94.

Hopefully your engine will say 92, 93, or 94 so that you can be 100% sure what OBD it is. Because there might be some overlap in 1991 where early in the year OBD0 motors may have still been manufactured.

this thread has a more detailed image. This image is from a D-series engine but it applies to the B series engines as well.

other than that, your only option is to check the VIN on the engine as mentioned in post number 5 in that thread.

Hope that helps.

 

It should be obd1 my gf has a gsr thats obd1 should be the same

 

This. Since almost everything can be swapped on a B, this is the only way to be sure you get the right dizzy.

Unless you know it's all original, year doesn't matter, VC doesn't matter, yadda, yadda, yadda,

 

thank you all. i will check the year and if that doesnt seem to work for me i will let you guys know. hopefully this is useful to people that search,
oh and vtec is bigger than dohc on my vc

 

The valve cover has nothing to do with what year/ model it is. All Vtec B series valve cover are interchangeable. Take a picture and ill tell you what it is.

 

Here's a better question:
What ECU are you using?

 

Well then I can tell you that at least your Valve cover is not from an OBD0 engine lol.

 

He could be running any ecu.

 

take a picture because at this point it doesn't matter what year the car is or even what engine year it is. It could be an OBD0 car that someone converted to OBD1 or even vice versa. Also all b series VTEC distributors bolt up to each other so he could have an OBD0 motor with an OBD1 dizzy or vice versa.

 

Look at the code on the motor. Its under the B16A. I beilive anything starting ing 5xxxxxxxx is a Sir II. Sir I is 1-4 i beilive, google it and see what they say. Sir II is obd 1 and sir I is obd0

 

like the guy said above...the best way to tell is take a pic of the dizzy n plugs..that will determine the OBD..i believe OBD2 has one big plug, OBD1 has 2 plugs 1 is rectangle and the other is square i think, and OBD0 are both circles...i have all 3 Dizzy and that's the only way i can tell the difference..

 

sorry guys, lost net for a bit.
but im taking pictures now.. will be up in a sec.
