Converting R32 Gtr Diff To Fit In Gts-t

Recommended Posts

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.

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.

    • Gosh these bmw's are worse money pits than JDM's! I won't complain about my car anymore 😂
    • I'll just leave this quick tip here after reading your joys of getting the car in the air. It should take no more then 10 minutes to get the car safely up on stands.  So for the front, jack on the tow recovery points (marked in red). Put the jack stands under the lower control arm mounting point (marked in yellow). This photo is of a R34 GTR, however the process is the same. For the rear, jack under the diff (marked in red). Put the jack stands under the rear subframe or where the lower control arm mounting point (marked in yellow). Which point you use will depend on your stand, pick a nice stable point.  You've probably already read this but it's worth repeating. When jacking up the car or using stands, stay away from the chassis rails/pinch welds. Even the factory jack point, stay away from that too unless using a factory jack. I used those jack points for years without issue until I turned into an old man and bought a QuickJack lol. 
    • And this is where the leak is happening: https://www.dropbox.com/scl/fi/7h1vlmg2j5aa7rksvsjc9/IMG_9982.jpeg?rlkey=d3bnpau5f615zmxqmca0llvr7&st=kquvdxvs&dl=0   Apologies but it seems adding an image from a link does not work when the images are in Dropbox.

    • Hi all, From the western suburbs here. Just got my 2000 R34 GTT registered today! Got it imported from Japan through a mate who is doing them and managed to find a decent one. This one has only done 110,000 Km and had no body rust etc. so was very happy. I used to own a 25Gt back in 2015 (ate Ramen noodles for years to save up for it), but unfortunately, it got stolen TEN DAYS after I bought it!! Came back from Uni and the car was missing - cops found it in Springvale a month later with a lot of needles  😒 It was too late by then and I had moved on to a different car (300ZX), and after that one got broken into around 2018, I was in a very bad place and decided I would never buy a car again because it was just pointless!!! ~yeah, I have some very bad mojo~ 🥺 But now, with a stable job and a secure garage, I thought I'd get the R34 4D again but not as a daily! I love the R34s but a GTR is still a bit off my pay grade so settled for the GTT instead.    The first step for me is to get this car serviced and have all fluids, belts and spark plugs changed. I might do the brakes at one point too but atm they are fine, the fluids are what I want changed since this car probably sat in a garage for a long time. I'll then get some coilovers since the suspension needs to be changed anyway (the dust cover kit is disintegrating). I'll also upgrade my car alarm to a Viper system and then look at rims and tyres (I'm a sucker for TE37s - might have enough saved in another 3 years for that).   Today: I was planning to do the oil, coolant, air filter and fuel filter change this week. Started on the oil change today and MY GOD what a pain!! I used to think the 300ZX engine bay was cramped - oh I was so wrong! 😂 I've done the usual services on my cars before so it was not like I was going in blind. I looked up all the forum details about what oils to use, what coolant to use, what points to use to jack the car or place stands etc but I did not expect it to be this hard. Long story short - all I managed to do was the oil and filter change. I think I might end up taking it to a mechanic for a coolant change because my SCA stands and trolley jack just can't get far enough underneath to the cross-member and I don't want to be crushed under my favourite car....yet. Side note: In Dandenong, there used to be a shop that lets you hire their hoists - does anyone know if they have those around? I can't seem to find the Dandenong place anymore. I contacted them off FB almost 6 years ago and I'm not in it now. If anyone know of one, that would save me some time going to a mechanic for the basic services. Oil: Dark and gooey but no metal pieces. Oil Filter: Was a b***h to take off but no red flags Air filter: Yucky! Was black (Smells like fuel which makes me think it may have been running rich? - am I way off?)   Concerns: I have but one concern atm and that is that there was a very small amount of oil leaking where the engine and the transmission connect (Automatic). It may be the rear seal? It's not a massive leak and it does not affect the oil pressures or leak oil all along the driveway. It's been falling into the cover this whole time. I've taken the cover off so I can check the garage floor from time to time.  I also have not seen my engine temperature gauge ever sit at cold and slowly move up to the right spot, but that might be because every time I saw the car today, it was running. I'll check that again tomorrow. ATM it just sits right in the middle. I may just be paranoid but I don't want an overheating engine while my gauges say everything is fine. 🙈 Other than that, I'm very happy with the car! Feels like it's about time I went back to spending my weekends driving or cutting my arm on stupid sh*t in the engine bay.   PS: I will post a pic later on because I underestimated soooo badly today and it was dark by the time I finished! PPS: I broke the two damn plastic pins that hold the intake funnel section to the front bar. This is the piece made to bring cold air to the airbox. The connection to the airbox is fone, but the two clips just broke off! Should I be worried? Anyone else done that?
