Dead O2 Sensor, Where, Who, What?

So my O2 sensor reads 0v at all times and I'm getting weird AFRs, up to 18:1 at idle making it pop but drops as low as 12:1 on cruise, tune has been looked at and is fine, going to replace the O2 then get it on the dyno and make sure everything is going smoothly anyway.

Now I have an rb25det with a rb20det computer, I'm assuming they probably are the same sensor between everything from R31s to R34s but just in case I will get the one for the r32 rb20det.

So brands, dealers etc, who makes ones that are the same fitting as stock and similar voltage scale eg 0-1v? and who should I contact to buy one? I would call all the usual places but I don't trust them to do anything other than read a book, would like to hear from someone who actually knows what a direct replacement is.

Ultimately would like a stock plug as I can't really be bothered wiring a new one up, but if I have to I will.

Help much appreciated.

i prefer to buy them via http://www.oxygensensors.com/index.php?&am...amp;height=1080 but it is in the usa (only $47) so wait or buy local ;)

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
