O2 Sensor Compatibility

[SLVR32GTR]

Hi Guys,

I am almost ready to do my turbo conversion on my R32 GTR, but there are a few things left that i have to get first. One of these things is some new O2 sensors. I picked up some split dump pipes a few weeks ago and they are for an R33 GTR which run O2 sensors with a slightly bigger thread i believe. I have heard that you can get bungs that will allow you to fit the 32 sensors which are slightly smaller in thread size, but since im getting new ones, i dont know if this will be necessary.

So long story short, are the R33 GTR O2 sensors compatible in an R32 GTR??? Is there any other O2 sensors that will work?? (i have heard that the O2 sensors out of an EL Falcon work)

Thanks Guys,

Your help is appreciated!!!!

go to repco or autobarn and get them to look it up in the NGK book. i know they have a listing for R32 and R33 gts-t (i bought one for my r33 gts-t). one of those might be compatible. the r33 gts-t might be the same as r33 gtr, as the same plug does the sr20 motor as well.

you must use bnr32 oxygen sensors for the stock ecu.

they are itanium or some form of unobtainium and must match.

NGK have it on their site, under sensor finder, they list two seperate part numbers for the front and rear 02 sensors, as the plugs are different

R32 GTR Runs "Titania" design plugs, i think the r33's run "Zirconia" style sensors, aka. not compatible, you would have to speak to repco about titania wit the larger thread, not sure on what would be compatible...

if you can get a reducer for the hole, you can get 2x RB30 ones, OTD2F-2B and chop and change the plug on one of them over and the other one will bolt straight in

should say on the plug what they are, OZA... part numbers are the Zirconia ones, OTD... are the Titania ones

Yeah R33 runs Zirconia "OZA395", R32 GTR computer needs "OTD2F" Titania

Ok, thanks for the info guys.

Later down the track i will be running a Power FC. I was wondering if running the FC will allow you to run different O2 sensors, as the same FC is combatible on both 32's and 33's (GTR obviously).

Also, does anyone know where you could find bungs that bring the hole diameter down to the 32 size?? I know the HKS dumps come with them standard.

Thanks

If your running a PowerFC it doesnt matter as far as i am aware.

Not that ill be running them anyway, just there to plug the hole once the PFC goes in

I guess ill have to grab a stock R33 GTR ECU for the Emissions test though.

As ive got 33GTR Dumps the same as you do

Awesome, thanks for the info mate. I remember talking to my mechanic the other day about that actually, and he said that they hardly even use them once they tune up the Power FC properly, as they can get better efficiency without them.

I am now thinking about just sticking with my standard O2 sensors until i get the FC in!

Oh yeah, my dumps also came with plugs for the O2 sensor holes! So i dont even need old O2 sensors to plug the holes!

Old post I know but can anyone confirm if the 33 o2 sensors will infact work on a 32 gtr if you r using a powerfc?

[Beer Baron]

they should do providing you are talking about 33 GTR sensors. 32 and 33 GTR both use the same model Power FC.
