Help: R32 GTR - why two different o2 sensors? Anyone used the EL Faclon in a GTR?


Recommended Posts

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)

    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
    • Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo
    • Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
