S13 blacktop O2 sensor

[onefst240]

Ok i was looking to see which o2 sensor i can buy local instead of buyinga real sr20 sensor and i did a little search and found 2 different year 300zx for the sensor. Now my question is which do i use? 87 300zx or 95 300zx turbo. Is the 87 the skinny type and the newer 300 the fat type? Any info would help Thanks

IIRC...the 87 is the fat type. Skinny ones are off the sentras. The only issue I had when I replaced mine with the 87 Z31s is that the wire wasnt as long as my old sensor.

You can use the 02 sensor from your KA24DE they have 2 fat 02 sensors on them. This is what I am currently using on my car, no problems at all.
