im going to do a gsr swap soon and i just wanted to know if the jdm obdII gsr had 1 or 2 o2 sensors. i know usdm obdII engines have 2 o2 sensors but i was unsure about the jdm gsr.

 

it has two still

 

so if i were to get a 94-97 gsr from hmotorsonline (hypothetically speaking) how would i know if its REALLY obdI or obdIIa? besides looking at the 4 circles stamped on the block, would there be any other way?

 

I guess you could call them and tell them which one you need,im sure they would be able to help you out, I heard they have really good customer service

 

This is correct you can ask for either an OBD1 or OBD2 engine, I contacted them recently and they told me they have both.
