In the future I will be doing a turbo b18c1 obd2a into a 88 hf, I have two four wire o2 sensors from a 97 gsr exhaust, my question is will these same o2 sensor work properly for the swap and being on the header bung or? Also on this whole swap where would I need to put how many o2 sensors? One on the header, one near or in front of the catalytic converter?
Thanks,
Kevin

 

Here is a suggestion. Go OBD1 with your setup. You will save yourself alot of headaches in the long run.

 

Oh sorry thats what i meant I was doing. Im going obd1, doesnt obd1 need 2 o2 sensors, and whether it does or not, what about when im running the turbo?
