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

ok, have replaced my o2 sensor with the ngk one for an r33 gts-t

part number 0ZA395E2AB

no difference to economy so far :yes:

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.

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.

Cheers

ayone got an answer for the above?

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.

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

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?

    • I do believe from context he is talking about a S0/S1 R33 RB25 with associated ECU and Wiring for that, and a manual gearbox into a R34 N/A Auto. I don't have the knowledge of all the pinouts and such but my gut feeling from doing my own conversion is to use as much of the R33 stuff that you can. The "car" wiring is quite seperate from the "Engine" wiring when all things are considered. The only things to truly consider 99% of the time is the cluster, reverse lights and potentially disabling the 'not in P/N' immobilizer circuit.
    • A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway. 
    • Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).
    • I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as 
    • Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement
