Hi Guys im after some info which is not available here in the UK on this rare engine model but you do seem to have a few here ..the lambda/o2 sensor part number is 22690-70T01 and im having trouble matching and finding out weither its a titania or a zirconia type sensor...the R33 GTS-T models have a 3 wire zirconia sensor with 2 white wires and a black...my RB20e also has a 3 wire sensor with wire colours of red/black and white...on the lambdasensor.com site there saying that sensors that have a red wire are the titania type but after contacting lambdasensor.com im told that nissan also used a zirconia sensor with a red wire so im comfused as to which type of sensor i have for my 1996 rb20e r33...
