i'm almost done with my gsr swap, just a couple of things left like the exhaust and linkage. I know every step for this swap except the one regarding exhaust. I was putting my exhaust back on today and realized that my civic (d16z6) o2 sensor was near the cylinder head in the exhaust manifold, and thats the only one i have. But i started thinking, the gsr exhaust manifold and downpipe does not contain an o2. so my question is,


where is the o2 sensor located on the integra?? is it post cat? pre cat? are there 2 of them?

by the way i'm running an obd1 swap so i believe its just one o2. would i have to add one to my stock civic exhaust?

 

I beleive it's on the cat. before the catalyst, If it's a obd-2 cat, there will be 2 on the cat, one before the catalyst an one after. you can go buy a bung or nut that fit the o2 annd drill a hole and weld the nut on there, and extend your wires.

 

if its obd2 there is an o2 sensor at the end of the down pipe rite b4 the cat and the 2nd o2 should be towards the end of the cat

 

its an obd 1 guys! so i should be allset if i add one before the cat right?

 

any ideas? and do i really need to wire in the knock sensor?
