heya everyone,

i have a series 3 r33 gtr non v-spec

now ever since i have bought this car. i have noticed that it feels like it has a lsd diff in it.

when i turn a corner to do lets say a 3-point turn, it will make the doo doo doo noise like the rear wheels are tryna both spin.

it has always done it. now im not sure thats why im asking you guys if u could help me out as it has me stuffed lol

so my real question is. do the series 3 come out with lsd ?? or maybe the guy in japan fitted a lsd into it ??

there is no light on the dash like the v-specs do by the way

tanks for the help in advance

chris.

You should have a LSD light in your dash, in the centre between your Speedo and Tacho.

If it is making a "doo doo doo" noise and both wheels are spinning, it might sound like you have a Lock Diff.

1 or 2 Way Lock Diff, I am not too sure...

all GTR's have LSDs (so do all GTSt's BTW)

non Vspec have a mechanical LSD diff... its got clutch packs in it so it will lock on tight turns depending on how worn the clutch packs are etc... it may have been modified to lock tighter/earlier... the Vspec diff is an electronically controlled viscous (fluid) diff (which is what the light is for on Vspecs)

mine does the same as yours in car parks etc and has not been modified... its a non Vspec... my old GTSt had a Cusco 2 way mechanical in it and it was even louder and more aggressive... but also made loud clunking sound and vibration through the driveline, I'm sure you would know if you had an aftermarket mechanical diff, they are pretty obnoxious lol

ahh ok that makes perfect sence... sweet so now i know i do have an lsd diff :D

thanks for the info guys

it has the torque split bottle in the boot

That's for the ATESSA system, nothing to do with LSD/non-LSD.

GTR's had LSD on the rear's out of the factory, if you have a R33 , finned diff's are Viccous LSD, non-finned is mechanical.

I think R32 might have been the other way around.

Either way, unless someone downgraded you to non-LSD you have one :laugh:

i get a few clunks in my drivetrain (r32 gtst), like crusing in 5th gear going say 60, backing off the accelrator and going back on, even if its not heavily, the rear end seams to knock abit,

    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
    • Hi @Chupapy i had several leaks from coolant pipes being corroded, i also had one leak on back of the head onto transmission. For me that leak was from the turbo water line. Follow the line to the back of the head The hose and metal pipe had perished these are the best pics I took of it at the time
