Does the early model S13 blacktop use fat or skinny? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Sorry, need to place an order and searching isn't helpful.

(When I search I see that the blacktop S13 SR20DET uses the "fat" type, but nobody distinguishes between the E5 and J4 so I wasn't sure if they used different 02 sensors or not)

all blacktops should have the fat o2 sensor. Be careful, its possible that someone swapped a redtop turbo elbow onto the engine.

Ah crap. That's no welcoming news.

I took this a few minutes ago:

Damn sure looks like you're right.

So, my engine has been running ok with the skinny. My ECU is E5 though. This smells like trouble.

i have the one u need i think...came off a 98 KA which im told is the same sensor the sr would need

ill take a pick of it if u want

RWD sr20det o2 sensors will interchange. They all use the same plug.

And I don't think ka o2 sensors are the same. I know for sure the pre-cat is not. Its just a one-wire. And I doubt the post-cat one will work either.

I know the fat o2 sensor interchanges with the 95 300zx TT. I forgot what the skinny one interchages with. Maybe the 90 300zx TT?

I think the skinny is interchangeable with the 87 Z Turbo.

Nuts, nuts, nuts. Alright. I'll order one and if it's wrong hopefully I can exchange it.

Moon Ill · 10-25-2009, 06:16 PM

Just to confirm.

The skinny and fat o2 sensors read the same and no re-wiring or repinning needs to be done?

On a '95, yes. '96-'98s use the same 3wire front sensor.

95+ FWD SR20 O2 sensors are interchangeable with the fatty's.

I have a stock blacktop elbow for the fat o2 sensor if you want to buy it, It comes with a working sensor too. Its just laying around.

I was going to replace the sensor with a new one since it's old, but thank you for the offer.
