Looking to piece together my turbo kit and i was just curious what to do with the O2 sensors after the header, do you run O2 sims or just install them to the down pipe?

for the obd I cars, you just make 1 02 sensor feed both 02 sensor wires.

I've learned that OBD2 SCs are little bit more difficult to turbo than OBD1.

Get bungs welded as far on the downpipe as the 02 sensors will go and install 02 sensors. No problem for me.

Correct for the fronts, but you will need a simulator for the "after cat" O2. (unless you really
have a cat)

ahh good point. check engine light goes on when you go catless on the last O2 sensor.

Casper electronics (O2 simulator). Get them here or any speed shop, you need a 4 wire.
Search to find the install, been done many times.

Sorry to dig up an old thread (I did search here and clubna-t) but by the title I figured I would ask this in this thread to keep all the info in the same spot. I am in the middle of a NA-T build in my friends 92 SC300. Since the DP has thread in style O2 bungs, and the stock sensors are flange style, what sensors should we use? I have read about using one sensor and feeding the signal to both bank 1 & 2 but is there a thread in sensor I can use for the signal. I would prefer that over welding a new flange in the DP for the stock sensors.

Thanks in advance,
Ki
