I take it the helical diff in the R34GTT manual is an improvement over the R33 gtst viscous LSD.

Were these in all the manual R34gtt's or only after a certain year model?

Has anyone had problems with these/comments?

Does it prevent the inner wheel spinning that occurs with tired VLSDs?

All I can say, having recently bought one from a manual (it was 4.11 ratio) that was viscous....they're not helical. That's if any were helical at all. The R34 sales brochure says the manuals are helical and the autos are viscous, but that may well have only been after a certain date. I certainly have never seen a helical yet, and I've been looking.

yeah they are vicous. 34 GTRs are not helical. they are a clutch pack mechanical type LSD. or if v-spec they have an active LSD which is similar but governs the amount of slip using hydraulic pressure in the diff (with an electric pump).

best bet is just buy one of the many available mech LSD options out there. there are plenty in the $1000-$1500 range and even cheaper to buy second hand. or use a 32 GTR diff and buy a set of nismo clutch disks for it. should be less than $800 all up and it's as good as a brand new mech LSD.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The cam I am actually putting in (a few posts up) is actually smaller than my current one. At least duration/overlap wise. All the chop stuff I hear just sounds like an engine running badly, because it is. I then envision driving it around in 1st gear and being massively sad about it bucking to the beat of said chop. There is an idle video of someone with a similar cam floating around the internet, but mine is a custom cam (so is his) so it'll never be the same, plus the fact exhausts are entirely different. What I want to do is put some bullet mufflers/race mufflers in to replace a couple sections straight pipes that currently replace the two extra cats that I don't need. But this is even further down the line!

      I can tell you now, when the bracket that the little hydraulic ram attaches to snaps, with a subframe, and V8 from an AMG C63 on it, it sounds like someone letting shotgun off right beside you. It leaves your ears ringing, and a huge thankfulness that you never ever put a body part under something heavy that's only supported by a hydraulic lift...

      Water leaking into the rear trunk

      By Neostead2000 · Posted

      Still not a guarantee fix. I used a high quality butyl-mastiq (the black goo that's not really silicone nor polyurethane, same stuff they use from the factory that just spreads out like melty cheese), and I still get lots of water on both sides of the trunk when raining or washing the car. I also suspect the factory spoiler rubber gasket might not be sealing well, so I'm thinking of adding a thin layer of grey silicone around the bolt holes on both sides and see if that's where it also leaks from. The biggest issue is that these cars don't come with a drain hole on each side like other coupes and hatchbacks.

      I hate it, but maybe he could paint it Monster jam style and call it...godzilla?

      Would seem to me to be appropriate to go GTR style bar. There are options with and without N1 vent holes, with the GTR lower lip integral (because FG copy). https://justjap.com/search?q=r32 bumper
