Ok, not sure if this is a subject covered before but I'd thought I'd bring it up.

People talk about fitting a fuel pump to their Stagea but I haven't ever seen any detail about it.

I currently have a Walbro 255 in the tank behind the 26 but to be honest its not right. It won't run right when its cold (like its starving of fuel) & if you thrash it it doesn't seem to catch up for a while. Talking to a fuel pump expert he said that some Nissans (Z32 300ZX for example) run variable rate earths at the ECU & that may be what is causing my problem. I personally have a re-shelled 260RS if that makes any difference (including the entire 260RS wiring loom) so I'm just curious as to whether anyone has had fuel pump problems with their Stagea/260RS.

I have access to a Bosch 044 with a the appropriate fittings to adapt to the Nissan setup but have been told (by the same guy) that I will at the very least need to change my fuel pump relay for fear of burning it (or the wiring/ECU) out. Of course I haven't wanted to risk a 260RS ECU so haven't taken it any further.

I'd like to wind the boost up to 1 bar but I don't want to risk a lean out with a sketchy pump so I'm holding back at the moment but I can tell you my RH foot is getting itchy.

What are other people running in their Stagea/GTS25T/GTR etc etc?

On a similiar note; how do people wire up secondary fuel pumps? Into the same earthing point (via the ECU)?

I think sydneykid has mentioned it before, the Walbro needs 13 + volts to perform at 255l/hr

You may only be getting 11 volts and therefore your pump is not pumping enough fuel for your thirsty rb26

Ahhh I see. That makes sense.

I had considered hard wiring the pump with a direct feed from the battery but my concern is of the safety side of it; I don't want it to keep pumping fuel if I ever crash it (well if someone crashes into me :blink: )

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
