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)

    • Let's hope that's not a copy pump either. There were so many copies of them back in the day.
    • Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys
    • Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels
    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.
