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

  • 2 weeks later...
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,

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
