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?

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
