I'm swapping a JDM F22B into my 92 s but the exhaust manifold that came on the F22 doesn't have a spot for an O2 sensor. Do the JDM motors not have O2 sensors? or do I need to use my old exhaust manifold and O2 sensor?

Also I'm using the jdm ecu if that helps

 

The F22 sohc has the O2 sensor @ the manifold right?
The F22B has it just before the collector (behind the oil pan)

 

Yeah the sohc one is on the header underneath the heat shield
Would it be fine to run it on the manifold?

 

From your posts I gather u didnt get the F22B downpipe, only the header?

The H23 header/manifold will fit the F22B and if it were me, Id extend the wires and run O2 in the stock locations for the F22B (same location for H23/H22)

 

Yeah it didn't come with the downpipe but I do have my old one from the si laying around somewhere in the garage so I'll just use that. Thanks for the help
