Cubes Posted February 7, 2006 Share Posted February 7, 2006 200rwkw via PFC? Throw it on the dyno and see what afr's are. As mentioned prior, dirty injectors were my problem.

Spook's_Skyline Posted February 11, 2006 Share Posted February 11, 2006 ok, no improvement in fuel consumption with new o2 sensor was reading on another forum that before i was gettin like 300, until i replaced the charcole canister.. seems to better now.. could this help? i believe my charcole canister is unhooked Link to comment https://www.sau.com.au/forums/topic/43095-o2-sensor/page/10/#findComment-1941649 Share on other sites More sharing options...
lwells Posted March 21, 2006 Share Posted March 21, 2006 So has anyone found drop in replacement for the R32 GT-R. I just got pricing on genuine Nissan ones, and even at (supposedly) club pricing the pair costs $449...............!!

Busky2k Posted March 21, 2006 Share Posted March 21, 2006 ok, have replaced my o2 sensor with the ngk one for an r33 gts-tpart number 0ZA395E2AB no difference to economy so far what else can cause poor fuel economy i dont get more than 300ks a tank from a 200rwkw gts-t (via usual mods, powerfc etc) Changing the O2 sensor alone when you have a PowerFC won't really help. As cubes said, chuck it on the dyno and get your low RPM and low load cells checked out. Try get the tuner to tune them as close to 14.7:1 as he can, and then let the PowerFC O2 feedback do the rest.

l3aller Posted April 5, 2006 Share Posted April 5, 2006 Hi i dont know if it already been posted but ebay have universal sensors for 56bucks delivered. Link to comment https://www.sau.com.au/forums/topic/43095-o2-sensor/page/10/#findComment-2074555 Share on other sites More sharing options...
Duncan Posted April 5, 2006 Share Posted April 5, 2006 there are at least 2 sizes in titania and an alternative zircon style sensor, so what sort of "universal" are they?

Cooper Posted April 6, 2006 Share Posted April 6, 2006 Does anyone have a yes/no answer as to whether a O2 sensor from an R33 GTST will fit and work on an R33 GTR? It doesnt matter about plug type i just want to know whether it fits in the thread and works with the computer, an answer would be greatly appreciated.

Rolls Posted August 18, 2006 Share Posted August 18, 2006 Follow the exhaust manifold > turbo > dump pipe Itll be screwed into the back of the dump, looks like a short cylinder sticking out with 3 wires.

d00dz Posted September 7, 2006 Share Posted September 7, 2006 Pic of what I did with the stock plug and an EL Falcon oxygen sensor: Btw NGK have a direct replacement for the RB25DET engine. Part Number OZA395-E2. ~$125 - $145 from repco Needs some heat shrink around the individual wires will do that tonite.

Nozila Posted October 25, 2006 Share Posted October 25, 2006 just purchased this earlier today and installed it/took it for a drive earlier and it seems to fixed a few issues i had. 1/ doesnt seem to hunt on idle anymore 2/ it now boosts better then before 3/ it rev's more freely. at the same time, i changed my fuel filter which i think assisted with the change in characteristics Link to comment https://www.sau.com.au/forums/topic/43095-o2-sensor/page/10/#findComment-2614630 Share on other sites More sharing options...
Cubes Posted October 25, 2006 Share Posted October 25, 2006 Its all in your head. The o2 sensor won't have it boosting better. As soon as it starts booting its well and truley out of closed loop mode and running purely off the maps.

Nozila Posted October 25, 2006 Share Posted October 25, 2006 ok, let me correct no. 2 i use to have a kinda surge feeling when i boosted it. it would only boost to about .1 bar when the accelerator was flattened and just feel like its lost all power and then pick up again. makes it feel really bad and kinda like its cutting out and then boosting again - if that makes sense. now however, it boosts fine and feels like it pulls harder. i drive the thing so i would know the before and after effects. but having said that, technically wouldnt a working o2 sensor help the ecu adjust its a/f ratio when boosting?

Cubes Posted October 25, 2006 Share Posted October 25, 2006 Technically the o2 sensor is ignored before positive manifold pressure is seen, so technically it wont make any difference to drivability apart from vacuum load.
