Converting R32 Gtr Diff To Fit In Gts-t

Hey guys,

After a bit of advice... I want to put an R32 GTR diff into my GTS-t. I looked at changing the whole cradle but don't want to do all that, and have the wheels poking out the guards!

I've heard the front yoke can be interchanged with the GTS-t diff, but what about the side stubs?

I *think* there are a different number of splines between the two.

I know the connection to the half shafts is different.

I have a whole GTR rear cradle to play with.

My questions are:

Can custom ones be made?

Can I cut and weld them to make what I want?

The half shafts from the GTR are longer - can they be shortened and put in?

Is there an easier way to do this? Any other advice?

I have no faith in the GTS-t diff, I've been through two and from what I've heard the viscous LSD's are shit.

Thanks in advance for any replies. You guys are worth your weight in gold.

Bobby.

You should be able to use your GTSt cradle and bolt in the GTR half shafts and the GTR Hubs - The extra length of the half shaft apparently isn't an issue.

Nathan from "O2 Autosports" has done this very thing to his GTSt Drift car, so if you need more specific answers, give him a call (02 4423 0977). I'm sure he'll be keen to help.

I have helped a friend put it in a 180SX,

you will need:

- GT-R diff (complete)

- GT-R shafts

- GT-R hubs

AND I vaguely remember the holes being different sizes so you will need washers to suit

Thanks very much for the advice - I gave Nathan a call, he was a top bloke, gave me lots of advice. I'm going to give it a go this Saturday, I'll let you know how it goes!

i had this done just last week all up was bout 6 hours labour diff out,diff in, there is a few threads of memory that tell you what needs to be done, depending on whether you have coilover suspension or not you may need to take the suspension mounts of the gts-t cradle and use them on the gtr

All done! Was a bit more work than we realised but it sorted itself out in the end.

A few things we noticed:

The GTR hubs have the handbrake crap on them, while the GTS-t ones didn't. So we had to use the GTR surround thingys (the things that the hubs bolt into)... meaning we had to use GTR struts (different bottom end) and lower control arms (bigger ball joint mount thingys)

We also had to change the back cover of the diff from the GTS-t one, because they have four holes that are closer together than the GTR's two.

I still have no definitive answer as to whether changing the diff yokes means bearing preload etc, but when we did the GTS-t yoke up onto the GTR diff it got tight. So we just didn't do it up as much and all seems fine.

The GTR diff is a bloody marvel. I'll never bother with the useless viscous LSD's, there is just no comparison!

We changed the cradle bushes at the same time, and getting the old ones out was the biggest prick of a job ever. We ended up using an oxy torch to light them on fire. It WAS worth it in the end - the rear end feels 100 times better. I just need to do the control arm ones now, to get rid of the stupid axle tramp going round left corners!

Thanks again for everyone's help and input, and hopefully others can benefit from the outcome!

Bobby.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.

      The downside to that is that the cost of everything, particularly labour, is significantly higher here than it is over there in the Disunited States of Slavery. You can hire 3 tradesmen over there for just the Ranger Raptor allowance of a single 3rd year apprentice over here.
