The R32 GTR has two different O2 sensors - eac has a different part code and price with Nissan. Anyone know why?

Since I have to replace both, I was wondering if anyone had used the EL Faclon universals?

Since the GTR is known to have a lean #6 piston, I'm worried that using the EL Falcon option might lean it out and blow engine up........ which would be very baaaad....

Would aprpecaite people'sexperience/knowledge in this area.....

The car won't lean out and blow up due to the O2 sensors, they are not refferenced under full load (WOT). They are there to enable the car to be fuel effecient at cruise (part throttle/light load) conditions. Can't advise you on using the universal sensor, but as long as it fits, and give the right volatage signals there shouldn't be a problem.

i would have a stab in the dark and say that one of the sensors may have a diffrent connector on it...this would be for front and for rear half of the engine...the reason behind this would be so that you dont connect them arse about....i would assume the actual sensor will be the same....just the connector would be diffrent....if not...just possibly a longer lead on it

Could be the case. ONe is a three pin, the other with 4 pin (but only 3 pins used), but there's a $10 price difference between them. I thought perhaps Nissan might be clever and use two narrowbands to get a wideband reading.......

So, has anyone fitted the Falcon EL universals to a GTR with GOOD Results?????

if thats legit ^^ then id look into that xfixiate. el falcon ones are 70-120 ish each?

Universal EL Falcon $100 new each from Petrojet.

But since no-one can seems to know the mapping between them, then how dya know that the voltage going back from the EL isn't read by the GTR CPU as too rich and the mixture is leaned up?

Burn your valves out or blow a piston to save a couple of hundred bucks?

I'd use them if I could get the data, or be able to talk to someone that has dynoed the EL Falcon ones on an R32 GTR and looked at the results....

Matts would be 2nd hand? Since they are supposed to be replaced every 40kkm I think I'll be buying new ($400 for both)

      After market rear camber arm adjustment

      By V35Newbie · Posted

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.

      Continental have consistently beaten the absolute shit out of every other performance tyre in Wet/Damp/Cold conditions and give up a little bit of time (half a second at most) in the dry. Almost like it's engineered for German conditions or something. I'd def give those a try.
