O2 Sensor Question

Just a quick question. I'm going to be running 1 O2 sensor on the dump pipe on my soon to be single turbo R32 GTR. The dump pipe is off an R33 GTR but will be modified to work on an R32 GTR. The bung that's on there is to suit an R33 GTR O2 sensor.

Can I buy an R33 GTR O2 sensor and fit it and have it plug and read correctly on my 32R? I'm going to be using an Apexi Power FC D Jetro for my ECU.

Thanks

yes BNR32 PowerFC is same PowerFC for BCNR33

the only difference is the 02 sensor type, as BNR32 from memory is titania, and BCNR33 is zirconia (forget which is which). Under ETC, FUNCTION SELECT you need to identify which one you have by setting 02 SENSOR REGISTER. read the powerfc in my signature to work out which one is which and set it and away you go. also make sure you duplicate the output signal to both 02 inputs on the PowerFC, ie make sure 02-1 and 02-2 under ETC, SENSOR SW CHECK have a working value

Forget the O2 all together.

Mine aren't even enabled... would get 500km/tank on the freeway given I managed 420km today and it was on 1/4 :)

Infact the GTSR doesnt have them enabled either and i can easily get 550km/tank on FWY and around 400 around town (bit lighter giving advantage there)

Thanks for the great info guys. I would prefer to have an O2 Sensor working in there tbh. Last question, how should I wire up both the cables so that both O2 signals get the same and accurate readings from the one O2 sensor to the ECU?

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
