Hey guys,

I have recently got my r34 sedan which had a 20DE, running with a RB25DET Neo out of a stagea, Everything is running mint except the fuel gauge, I have exactally 3/4 Tank and as I am driving it drops right down to "E" with fuel light on then it sometimes rises to somewhere on the scale then back to 3/4 again. and basically it appears to have a mind of its own. and yet if I turn the engine off and wait a minute before restarting it it returns to 3/4, Any ideas? I havnt changed the fuel pump for the turbo motor that I have put in, can anyone tell me if the 34 RB20DE fuel pump is different to the 34 GTT and Stagea 25DET? and also if that had anything to do with the above problem,

Cheers

mine's been doing the same thing only over the last 2 weeks though, and mines an rb25det standard from factory R34 GT-t (no engine conversion)

and i haven't changed or messed with the fuel pump either, and its gettin fair annoying not knowing how much fuel i got.. its intermittent though, like the last 3 days it's been fine, but i still dont fully trust it..

i don't know what it would be though :thumbsup:

My main concern is actually the part numbers of the fuel pump that is in the 20de and the pump that is suppose to be in the 25det does anyone know where I can find the numbers of both so I can tell if they are the same unit,

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
