i just got a new header for my 3rz and it came with an O2 sensor port on the tube down. My last header didn't have one, and the 02 sensor is farther downstream. Anyone have a link or measurements to where both 02 sensors are sposed to go?
Both the O2 sensors on the doner vehicle were right before and after the cat. I'm sure it wouldn't hurt if the upstream one was further upstream though as long as it's after the collector...
What header did you get?
I haven't forgotten that heat shield stuff for the fuel line, I just haven't been home in the daylight to take it off. I'll send it to you next week.
