Which o2 sensor do I need [S14 ecu running blacktop s13 motor]

[Kamronman]

Hi everyone, I am currently running an s14 power fc on my later model s13 blacktop motor. The pinouts are the same, just the harness is missing all the cam angle sensors etc (which are unnessesary for my motor to run).

I have ONE issue so far. My O2 sensor went out yesterday, I know because it reads only 0.00v, but when it picks up any voltage at all (when car cold starts or has been cooled down then restarted), it runs awesome, perfect afr's.

Btw, I have stock injectors, z32 maf, and a stovk power fc tune with minor adjustments to maf-voltage to dial in my afr's. (Recommended by a friend, and when I got the ecu had been tuned by a professional, these maf settings were set the same as I have them now).

Which o2 sensor do I need for compatability with kouki s14 motor?

I might as well add that I have my bov non-recirculated, will the added richness from that affect my o2 sensor life?

Late model S13 and S14 SR used the "fat" O2 sensor, just find a replacement. For my S14 SR I just ordered up a Bosch replacement for a 97 240sx and it was exactly the same as the SR one. The wire from the sensor to the connector is only about 12" long on the S14 (part # 13420), so if you need a longer wire, you can get one for a 96 300ZX (part # 13091), those leads are 22" long.

Costs about $35 from rockauto. Can also get from local autoparts store, they're not "SR20/JDM" specific parts.

you can use any narrowband sensor on the planet, even a 1-wire from a chevy truck in the 80's would work. just make sure you match up the signal wire to the ecu and it will work.

96 maxima plugs into my s13 blacktop...wiring is about 2 ft long...
