Oxygen Sensor Interchange for 1JZ
#2
I pulled the O2 sensor from the 1JZ. It's a three wire type.
I found a MK4 O2 sensor from a 1993 that is 3 wire exactly like the one I have. It's pretty expensive though. Cheapest I found is $121 at Rock Auto.

The jzz30 has a weird part diagram image. It shows :
(note, their are multiple part #s because one of the numbers got succeed by another)
Sensor, OXYGEN
89465‑29435 JZZ30
89465‑80015
SENSOR, EXHAUST GAS TEMPERATURE
89425‑29575 JZZ30
89425‑29855 JZZ30
89425‑29865 JZZ3*
As for the Supra
SENSOR, OXYGEN
89465‑19595 JZA80..TWT; RR
89465‑19605 JZA80..TWT; FR
and this gasket
89466‑20020
Now here is the interesting part. The soarer o2 sensor looks like a normal o2 sensor, the exhaust gas sensor looks just like the supra o2 sensor with the supra gasket on it.(your pic)

I found the part number on the O2 sensor. It is:
89465-22130
Doesn't match with the JZZ30/JZA70 1JZ.
I found out on SF that most of the guys run the MK3 7M oxygen sensors. However, mine is a heated 3 wire so those single wires may not work. I think I'll be buying the Bosch 3 wire.

Don't go the Bosch route unless you have to. I've heard they're not as good of unit as a Denso/NTK and my personal experience with them was that I was not impressed.

Update
I received the Bosch 13910 and quickly did a comparison. The form factor is a bit different between the two but the connector is exactly the same. I installed it and plugged it right up. Fired right up. A quick drive around the neighborhood is showing good results. No issues at idle or WOT. The car is definitely not running as rich as it was before.
Damn, does the sensor say NTK on it?
