o2 question - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a s13 Sr20 in my 95' 240sx, i am currently putting HKS Hi - Power exhaust on it. I have a stock turbo outlet then a megan DP, stock KA cat and the HKS exhaust.
From what i undertand there is supposed to be two o2 sensors, i already have the one in the turbo outlet but there is no hole for the second one? Should i get a bung welded on to one of the pipes and if so which one?

Any help?

Thanks guys

Is the o2 sensor behind the cat? I think you will have to weld a bung on there.

if you want, u can get a MR 3" test pipe. it already has a bung welded in.

The SR doesn't use a second O2 sensor. You don't need it.

correct, it depends on motor not car so it is not necessary

ok great thanks guys, so since i have the KA lower/Alt harness on the car what do i do with the sensor for the o2? Just tie it up and it wont affect anything?

Thanks again

I removed it and the rest of the useless wires/plugs out of my lower harness.

zip tie it up and out of the way.. would be good enough
