260Rs O2 Sensor Dilemma

Recommended Posts

Hey all,

after trying to diagnose a performance fault my tuner found the ecu was non communicative. Therefore the best option at the time was to swap in a 32GTR ecu and the problem was soon diagnosed and fixed. ECU runs great and problem was a faulty crank angle sensor. Only problem is that I had to disconnect the O2 sensors (which needed replacing anyway). As the 260RS originally uses the 33GTR ecu and the 32GTR ecu use different sensors (titania and zirconia) where do I go from here?

The issues are,

-Connection plugs are different I believe between 33 and 32GTR O2 sensors. Do they have the same wires?

-Thread size differences between the two, I believe 32 sensors are smaller. This can be solved with an adaptor I imagine?

Is it as easy as grabbing 32GTR O2 sensors and rewiring the connection plugs to suit? Then install with adaptor or have I missed something? I would really like to get some fuel economy back.

Cheers
