Okay as i search and search and read different posts, i have come to a conclusion that i am confused:confused: What type of o2 does the u12 take and what type does the u13 take?

Reason im asking is there is another thread in here about a u12 o2 sensor and appentley he is using the Skinny o2 sensor with his u12 ecu.

Now i have a u13 (supposely, Came with stock front mount) and a u13 ecu and my o2 sensor is skinny. Is it wrong???

Just want to clarify what o2 sensor these motors use, seems like a lot of people ask.

Thanks
Brian

i have seen the skinny o2 on the u12's and u13's

How bout this I have a USDM ecu(w SAFC2) with a bluebird motor and a USDM MAF can I still run the skinny 02 sensor from the 89 turbo Z on my bluebird j pipe with no prob.

k thanks gor the input, having idle problems with mine and want to make sure i have the right stuff.

my u13 had a skinny one....

My Avenir motor runs great using a U13 ecu with a skinny O2 one from an 89 300zx turbo. And the wires were long enough I didn't have to extend them. I also have a U13 MAF.

I used to believe that the U12 used the skinny and the U13 used the Fat one, but now I'm doubting everything. Check my thread here, maybe we can all work together.
