Well the NGK connector is light Grey and more solid looking with all the spade pins Vertical and positioned in the center of the connector. The R34 or BOSCH connector is black, maybe a fraction smaller and all the spade pins are Horizontal and thinner and positioned in the top area of the connector.

Might take some shots if I get around to it...

I haven't read ALL the posts in this thread so don't know just how expensive the Bosch sensors are but I just wanted to get mine done so got a genuine one through Nissan, took a week and $180 bucks.

probably not the cheapest way to go but took about 10 Mins to change over. Borrowed a mechanic buddy's O2 tool and the sensor came with correct plug and even the wire clip down thingy.

I can help with genuine Nissan R34 GT-t sensors for $176, and NTK R32 GTS-t & R33 GTS25-t for only $77. For full listing just check out within our trader section:

http://www.skylinesaustralia.com/forums/Nt...so-t135194.html

did mine on the weekend.

plugged the laptop into the car and found one o2 sensor stuffed. rang nissan up and wanted $225 each per sensor, and 2 week wait from japan.

or $98 each from auto1 but with rewiring and $60 for o2 sensor socket ( makes life a lot easier).

plugged laptop back in and reset ecu, and sensors are working. now just need to see how much better fuel economy is is like.

Mr Moo - you could have bought that NGK one for 80 odd and changing the plug over requires only 2 basic tools - something to cut with - and a pair of pliars to crimp the old and new wires together using about $1 worth of crimps - they ripped you off charging $60 to cut and join 3 wires!!

Bloody hell I install an entire xbox mod chip for that price!

In fact you only need one tool as pliers can cut as well!

R33 GTR sensor (front at least) is a Bosch A24-621 115 68290

Global Auto Spares Part Number 351-0187

Same sensor for the rear, only lead length and plug differs.

Needs a 22mm spanner

18mm Thread - 3 wire Oval plug on a short lead - Titania

Hope this helps some people

I just rang GLobal Auto Spares and spoke to Chris. He said that Bosch no longer sell the sensor with Global Auto Spares numbers 351-0187. Apparently the alternative is 351-0040. He said he just sold them to someone else. I told him it was a R33 GTR (or 260RS) and that it has a larger thread that the R32 and he said "yes, that's correct. We have the right one for you". Seemed like a nice guy and seemed like he knew what he was on about. I have ordered 2 of them. They only cost $77 each. I'll let you all know how I go. James you may need to update your website.

OK. The table is now updated. Did it have a Bosch number on it? Let me know if you ran across any problems.

BTW - if you want the table updated you should use the email link on my page. I don't visit SAU all that regularly any more. I'm always happy to receive updates though - especially the more obscure models. Keep them coming!

They arrived yesterday, but wife didn't pick them up from the Post Office. So hopefully I'll have them tonight and can let you know part numbers and if they worked. I'll use the email link in the future. Didn't notice it. Sorry

Well I just opened up the O2 sensors. The brand on the pack says "Global EFI" with part number 351-0040. The plug looks a lot like the front R33 GTR one. The part number on the sensor is OZA395-E2 KBA16693 and it says that it's a NTK sensor. I'll let you know how it goes when I install it.

Hmmm I need to look into this further. A quick flick through this topic shows that people have listed this sensor as an RB25 one. It looks like it's Zirconia and from what I've read the R33 RB26 one is Titania. I'll see what I can work out from the stock one.

Well I just went out and had a look at the car (Stagea 260RS - R33 RB26DETT)

-The O2 sensors have a much wider body than the new ones

-The plug on the new one matches the front sensor perfectly

-I couldn't really make out the numbering on the stock sensors, but it looked like a standard Nissan part number.

-I am definately gonna need one of those tube sockets :P

From what I've read in this thread, the R32 GTR sensor is definately Titania. A few people have mentioned that the R33 GTR sensor is also Titania. Can anyone confirm this for sure? I did a search for Bosch a24-621 which apparently was the previous replacement that Global Auto Spares used to sell. I couldn't figure out if this sensor is Titania or Zirconia.

I think I might give Global Auto Spares a ring tomorrow and ask him about it.

The latest on this hunt for R33 GTR sensors.... I just rang Global EFI and Chris has been looking for a Titania sensor with the large thread size that the R33 uses. He says he hasn't been able to find any. He has contacted Bosch who had nothing and he is still waiting on a reply from NGK, but is not hopeful. He said he is able to get R32 GTR sensors no problem, but they are a small thread size. Does anyone know if there is some sort of adapter to mount the small sensor in the larger hole? I'm gonna do a google search.

BoostedBarge, I am not at all sure about the titania vs zircon sensors, but I am 100% sure that the 32 and 33 gtr looms and ECU are interchangeable - which means that the signal they output must be similar enough to work from either type of sensor if they are different between 33 and 32. Keep in mind narrow band o2 sensor is a very simple beast.

Part# I posted earlier is what you need...

ngk part # for r33 is OTD2F-P1P. direct fit for front sensor (3 pin plug).

Get 2, change the plug on the rear one.

THanks mate, the problem is finding that sensor for the 33. Global EFI rang Bosch and NGK and didn't seem to have any luck. I'm thinking of using the R32 sensors with an adapter to make them fit. I'm pretty sure that my old GTI-R had an adapter from the factory, because it used a small size O2 sensor. Maybe I could get one from Nissan or a wreckers.

If your running a PFC you can flick between the zirconia and Titania calibration.

I can confirm the calibration is completely off/different between the two so there's no way you can get one working with the other calibration.

Only issue is the plug. :laugh:

Sorry, I'm still running the stock ECU :P

I just had another look at the O2 sensors... I don't have the socket to remove them yet, but using a mirror and my digital camera I was able to work out it is a Bosch sensor and has the number "A14-A21 141 ....." on it. I did a Google search and found this

http://www.trademe.co.nz/Trade-Me-Motors/C...n-169217176.htm

which confirms the rest of the part number A24-A21 141 63072

I found on another forum that someone said that the R32 is Titania, but the R33/34 uses Zirconia. If he's right, then I might be in luck. I'll give Global EFI a ring tomorrow and see if he can find out if that part number is for a Zirconia or Titania sensor.

Oh yeah, if anyone has a spare sensor lying around, I'd really appreciate if you could confirm the part number for me.

My R34 had:

LIC. BOSCH A24-A71 047 87280 but it is a RB25DET if you have the RB26DETT then you will have to use the Titania ones. the single turbo ones are all Zirconia...

NGK / NTK OZA395-E2 $85.80 was my replacement part which should work for both R33 and R34 (with the plug swapped on the R34)

Tool used was a standard 20mm spanner. The thread was 18mm from memory. Use the spanner on an angle as there is not enough room between the firewall and the exhaust pipe, and the engine and some other box thing... - so no special tool required

Click here for the NGK part

I rang Global EFI and they said that since the sensor has 2 white wires and 1 black, it is most likely a Zirconia sensor. He reckons he just sold a couple to a guy who owned a R33 GTR, so I'm just gonna go ahead and see how it goes.

The part number didn't help at all, because he thinks it is a Nissan number.

Also, I just purchased an O2 sensor socket for $22.50 from these people. I confirmed it was 22mm.

I asked at Repco and they said it would be $60!

How do you do this? Is it only in datalogit or can you access this from the hand crontroller.

For those with large dia bosses for small dia sensors, I picked up a pair of adapters from the local exhaust mob for about $35, screwed straight in. Pity that one of my original sensors looks like it didn't like being removed and replaced, or was dead previously without me knowing.

    • That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php
    • Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.
    • I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.
    • A lot of what you said there are fair observations and part of why I made that list, to make some of these things (like no advantage between the GSeries and GSeries II at PR2.4 in a lot of cases) however I'm not fully convinced by other comments.  One thing to bare in mind is that compressor flow maps are talking about MASS flow, in terms of the compressor side you shouldn't end up running more or less airflow vs another compressor map for the same advertised flow if all external environmental conditions are equivalent if the compressor efficiency is lower as that advertised mass flow takes that into consideration.   Once the intercooler becomes involved the in-plenum air temperature shouldn't be that different, either... the main thing that is likely to affect the end power is the final exhaust manifold pressure - which *WILL* go up when you run out of compressor efficiency when you run off the map earlier on the original G-Series versus G-Series II as you need to keep the gate shut to achieve similar airflow.    Also, how do you figure response based off surge line?  I've seen people claim that as an absolute fact before but am pretty sure I've seen compressors with worse surge lines actually "stand up" faster (and ironically be more likely to surge), I'm not super convinced - it's really a thing we won't easily be able to determine until people start using them.     There are some things on the maps that actually make me wonder if there is a chance that they may respond no worse... if not BETTER?!  which brings me to your next point... Why G2 have lower max rpm?  Really good question and I've been wondering about this too.  The maximum speed *AND* the compressor maps both look like what I'd normally expect if Garrett had extended the exducers out, but they claim the same inducer and exducer size for the whole range.   If you compare the speed lines between any G and G2 version the G2 speed lines support higher flow for the same compressor speed, kinda giving a pretty clear "better at pumping more air for the same speed" impression. Presumably the exducer includes any extended tip design instead of just the backplate, but nonetheless I'd love to see good pics/measurements of the G2 compressors as everything kinda points to something different about the exducer - specifically that it must be further out from the centerline, which means a lower rpm for the same max tip speed and often also results in higher pressure ratio efficiency, narrower maps, and often actually can result in better spool vs a smaller exducer for the same inducer size... no doubt partly due to the above phenomenon of needing less turbine speed to achieve the same airflow when using a smaller trim. Not sure if this is just camera angle or what, but this kinda looks interesting on the G35 990 compressor tips: Very interested to see what happens when people start testing these, and if we start getting more details about what's different.
