Do you need to drive it on the street regulary?

If not just get a VL V8 diff or a VL turbo diff just make sure that it is a 28 spline one and get a mini spool from ebay. if you break that you are doing well.

BTW i have a VL V8 diff here in Newcastle if ya need one PM me.

R31 skylines have a 4 pinion 28 spline from factory. Diff will be fine. I've only ever heard of a few axles shearing off, nothing to be concerned about. Having a spool will not be that nice to the axles in the long run but then again you will be drifting :P

thanx for the heads up guys!

i had the rb30et that im goin to put in my R31 in another car (VK not a VL) and had a 9inch behind it so i had no dramas, then i sold the 9inch to a mate and i put his V8 diff in and i blew it up in 3 days! thats why i was so worried!

i no im guna break stuff coz i will be driftin it, i just dont want it to be a weekly diff swap!

so the vl diff fits the skyline? i didnt no that!

anyother ideas ??? keep em comin

THANK YOU FOR YOUR HELP!

PS: this is going to be my regod Daily drifter, so dont want to make it undrivable

R31 pintaras have weak diffs/driveshafts, R31 skylines are strong as.

I daily drove an R31 with a minispool in it for 3 years, busted the tailshaft in it from a hard launch but the driveshafts took all sorts of punishment and were still perfect.

not sure if this is still active but here's my 2c

vl diff's do not fit unless u modify the mounts, but there is no point in that as others have previously said r31 diffs hold up just fine. i have had my 31 spooled for more than 4yrs and never broken an axle now its turbs and still holds up fine with constant thrashing

and to break a 28 spline axle it either cause it was already stuffed or you actually have the power to break em

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      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.
