I swapped a jdm B16A into my 89 si, tried to buy an injector (ebay) and it's for the wrong OBD. question is, how do i determine what OBD# mine is? search didnt turn up much.
Also, injector from different OBD B16 (b16a2 in a b16a) will it function or is it just sitting there? should i avoid emission testing/driving like this?

 

usually a B16A1 is a obd-0 obd-1 is a B16a2 alittle use of the search button would hurt

 

look at your ecu, what kind of ecu do you have??

Your probably OBD0

i did.

 

Check the injector plugs i think OBD1s are all gray OBD0 are yellowish/whitish also check the distributor plugs and o2 sensor because the ECU isn't always conclusive as to what OBD the engine uses.

 

how many wires does your o2 have

no, the op

 

2 O2 sensors, 2 wires each. dizzy has 2 wires also.

 

obd1...first gen b16 have 2 o2 sensors if I am correct...but dont quote me

 

read what ecu you have its probably pwo or pr3, see if u have a jumper harnes infront of your ecu. mostlikley you have obdo,

 

I have an OBD1 pr3 ecu. So pr3 can be 0-1. But dude just check out your ecu and someone will give you an answer.

Or you can look by the header stamp and it will tell you which year your b16 is
