the general maintenance question part on 02 sensors isn't really visited much these days so i would like the moderators to keep this post open untill i can get a few replies first, please.

I am installing a new front/dump and hiflow cat on sat and decided to save time and just replace the 02 sensor at the same time this saturday comming with abo bob....

my question is i just bought an EL falcon 02 sensor from repco for $71.99, I made sure that the thread would fit the new dump pipe i'm installing.... My R33 gtst series 2 has 3 wires for the 02 sensor, 2 white and one black, and the new 02 sensor has 2 black and one blue. I am assuming that the blue wire on the new 02 sensor connects to the black wire on my car, and i supose it doesnt matter which other 2 wires are conected to which????? can somebody confirm this????

i know this sounds like a simple deduction question but please no bullshit replies, only answer if you have reason to believe this is the correct way to connect them....

did the exact same thing to my car, and no, the colours dont make a difference. the blue goes to the black, and the others are the reference wires. you should have got a piece of paper with instructions on it on your new o2 sensor. should be on that.

ford el falcon 02 sensor works fine on R33 GTST

many have done so in the past and still working fine

my R33 has PFC and has ford el falcon 02 sensor and still going fine

in most automotive shops its easier to ask for a ford el falcon 02 sensor as its more common

if you say its a 1997 R33 Skyline they go - that car doesnt exist, or "isnt that 1987" - ie: R31 is only on their system

the sensor used in the R33 is a generic 3 wire 02 sensor, same as the ford el falcon 02 sensor

so its much easier to ask for a ford part cos its on all of the computers and they all stock it, plus it would be a cheaper part too

the ford el falcon one supplied will be a generic 02 sensor and not a specific ford part in a ford box with a ford plug

just a plain jane 3 wire 02 sensor with wires

the wires are heater, heater and signal

so the two that are the same colour are part of the heater circuit and the unique colour wire is the 02 signal wire (to the ecu)

as long as you match up the unique to unique and the two same colour wires to the two same on the loom you cant go wrong

      R33 GTR running -9 with no tune

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.

      So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.

      Squeaking clutch/throw out bearing

      By joshuaho96 · Posted

      Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
