    stock R34 GTR high EGT ?

    in RB Series - R31, R32, R33, R34 (1986-2002)

    Posted

    So I try to set the ignition to 15,20 or 25 doesn't make any difference..

    I have 2.6 bar at iddling on the fuel pressure line (taken after the fuel filter)

    I have 3.0 bar when removing the vacum hose or during the next 5secs I put the ignition on

    The fuel pressure is between 3.0 and 3.5 bars under WOT

    The fuel pressure is droping slowly continuously a bit after I switch off the car

    According to the service manual, these values are ok meaning pressure regulator and fuel pumps are ok

    I don't know what to do/test...

    The car is fully stock, seems to be in good health (no suspect sounds or lack of power )

    Any suggestions ?

    Hello,

     

    During highway around 3000rpm I'm at around 840 in sixth gear.

    During a WOT second gear to 4th gear I'm at 960 and I stopped at this point... (MFD starts to warn me)

    Engine iddling I'm at about 550

    I didn't pay attention in the past to this as I was solving others issues...

    The car is fully stock, everything seems to work good

     

    It looks like the engine is running too much lean ? Should I make some log data for the AFR ?

    I suspected the fuel regulator and the fuel pump to be 22 years old....Is it probably the issue ?

     

    THanks for your inputs

    sequential synchromesh r34 gtr gearbox ? (except quaife)

    Thanks a lot for your answers, I appreciate!

    Sorry I made a mistake for the quaife

    Well what scare me is one brand (I don't recall which one) advice to dissasemble the gearbox every 5000kms to check....and based on some reading here I can see that such gearbox need quite short servicing...

    I'm looking into the DCT which looks amazing !!

    Only downside is the final gear is "only" 1.00 for the GS7D36SG

    And also product is quite new so I hope we get some result/review soon !

    Option to upgraded the R34 transfer case ?

    in RB Series - R31, R32, R33, R34 (1986-2002)

    Hello,

    I'm planning my future upgraded...for a power goal of 800AWD with 1000nm torque

    What is the best setup to upgraded a r34 transfer case ?

    I understand that the order of the plate should be changed to steel/plate/steel and so on to have the best grip out of it.

    Are there any more robust plate than the original one ?

    Or maybe a strong clutch replacing the original disks pack ?

    Should I start with a r32/r33 gtr transfer case which as a bigger chain ?

    Is there any upgraded aftermarket transfer case existing ?

    Best regards

    So to conclude,

    My assumption was false, based on the curves I provided we can see that the wheels has locked but the ABS release some pressure to unlock them...

    Replacing the winter tyres by some regular tyres give a much better feeling too (but I don't think it was necessary)

    So at the end, a bleed of the system + some cleaning on the calipers (with a lot of WD40) seems to have done the trick....yes it was such simple

    French test has been passed with success this time

    I can finally drive legally in a few weeks hopefully

    THanks for having a look into my problem.

    I'm suspecting some solenoids being blocked as my wheels are still locking (my feeling is it seems to be the front only ) so I will dissasemble the pump
    I have made a test this morning (7am at 1 degre; the road was dry but we some humidity on it; sorry I don't get the english word for it )

    you can clearly see from the picture that my abs control seems to react correctly !
     

    if the solenoids valve are in good cobdition, I will put everything back to stock :

    • no winter tyres
    • OEM pads
    • new flexible hoses (avionic )
    • new brake master


    thanks

    I finally got a (german) consult

    I was able to do the active test with success (meaning the abs pump should be ok)

    the wheel data seems to be ok too, they are between +/-1kmh between each other and they are matching the real speed.

    I was not able to do the self diagnostic with the consult; I might do something wrong in the process I guess (see picture)

    so I have bleed the entire system and the wheels are still locking

    I have dixcel m or z type brake pads (I dont know if that could be an issue somehow )

    I have order a consult 1 we will see
    if I am still getting into trouble I will change the master brake cylinder, abs pump and abs control unit ...

    best regards
