All,
My r34 had an engine light on and it seemed the o2 sensor was dead as there was no input on my apexi turbo timer on A/F.
in the uk the cost of O2 sensor was around £150 so after long search of forums, I ended up buying one for nissan micra 1.3 1998 and fitted after changing the wiring on the O2 sensor so it could connected to the ecu connector.
here is another example of it in the uk confirming the o2 sensor works on Micra as well as Skyline

The car was ok but still felt as it was running rich so I changed the turbo boost pressure sensor and still seems to be mis firing .
The Boost pressure sensor item number was PS660-1 Hitachi boost sensor which match nissan navara 2.5 td 2002-2005.
It costs £80 from a distributer in the UK if bought for skyline so i bought it for nissan navara 2.5 td 2002 and it was half the price and exact same part number.
question is, if the part number is the same, should it produce a same output regardless of car it was on ?
Could I have messed up by installed an O2 sensor from another car? I suppose the reading will be the same so it shouldn't matter.
