Hey all, been a long time between posts recently. I have to move to Victoria at end of year and thought I better address a couple of issues with my car.

1/ Poor fuel economy. Will replace O2 sensor with new item. First question is does it have to be nissan genuine part or will any generic 3 wire O2 sensor work. What cost will that be?

2/ Need new air con compressor and get whole air con system overhauled. New Drier/regass etc. Where is a good place to do this on gold coast. Any ideas on what this will set me back? I figure in region of 600-700. I live at the Gold Coast

Cheers

Generic is fine, in my opinion better than the factory one as they have larger holes for the exhaust gas to flow through and don't get coked-up as easily....plus are cheaper. I've got one on my R34 and it's great.

Contact these people and ask for a Universal 3-wire Oxygen sensor e-bay oxygen sensor

i also have a 33 4door and get bad fuel economy, how does a new O2 sensor help fix this?

It enables computer to read fuel mixture more accurately. I have two skylines and did an experiment with swapping the O2 sensor, the car that was only getting 350km out of a tank instantly shot up 550-600km out of a tank of fuel on highway. On the highway it enables computer to run closed loop.

For only around the $100 mark I think it is probably worth the investment for saving so much fuel. They are meant to be changed around every 60000km or so, but this is just a guideline.
