Mine actually clunks and shakes the car more when cold but when it's warmed up it tends to just slip the clutches.

It is a little much for the streets and I gotta be careful around cops but pfft, I've had my cup of concrete for the day and love it ;)

yes my cusco 2way was like that too, just a dull thud whilst cold, but after some driving, damn nasty shuddering clunks!! I ran RE55's before too, so im sure that made it even worse!

will update once the OS superlock is in. Its back ordered till end of the month tho...

i added 100ml of penrite friction modifier (lsd additive) to my diff last night after thinking a bit more about it. this was added to the castrol synthetic traxsomthingor other that everyone is using. the stuff designed for the jag with the ford friction modifier in there already.

now it is a bit smoother

Nick I can't keep up with you. You're in Melbourne now?!

For everyone reading this thread. The bushes you use will make bugger all difference. The clear answer for those who want the performance without the hassle is to do what I did. R32 GTR diff. I had a Nismo in there before and yes sometimes I loved the clunks and groans and skips and when women pushing strollers stared at me I wanted to yell out "Yes I am the f**king devil. Look away before I burn your eyes bitch." but as mentioned by others here, some days it just gets tiring.

I loved the way the Nismo locked up on the track but day to day I'm much happier with the GTR diff. I may even get it shimmed up a little one day. Flirt with the wild syde again. :P

I assume the people who are experiencing noises and clunks didnt bed in their diffs?

You have to drive in a figure 8 pattern for about 20-30 mins for the plates to seat properly.This should lessen the noise,also a good LSD oil helps too.

what's involved in getting the GTR diff in there... did you have to change the whole cradle etc?

I bedded my diff in (figure8's in the carpark next to the workshop - yes, people were looking at me funny :P) and I have have clunks/chattering. Still running the Nismo oil that came with it, am going to change the oil on Sunday when the 25 box goes in.

Try some new oil first bro, I put ls90 in on the weekend and it's gotten rid of pretty much all the clunks etc.

It used to be an absolute dog first thing in the morning that it would shake the car, now it's barely noticable, can still hear the clutches chattering but it barely shakes the car in the morning and after driving for a while it doesn't do it at all.

I went for a test drive in a r34 today and the diff was jumping at low speeds, the dealer said he can take it to a diff shop and get it loosened so it won't do it anymore, i'll go back there during the week and find out if its true.

Does the diff jumping at low speeds wreck it at all or stress out any other parts?

yeah it will hurt the rear suspension a bit over the long term, its not great for it. If you don't want the tight diff they may be able to reshim it, or you could swap it for a stock one.

You dont need to change the rear craddle.

Basicly the R200 GTR diff bolts into the exact same position that the original diff uses. Before fitting the GTR diff you need to remove the tailshaft flange from both diffs and swap them over. (GTR uses a 6 or 8 bolt from memory mounting flange and the GTS-t uses a normal 4 bolt flange.)

You need to use the GTR drive shafts and the outter hubs so the Axle spline sizes are right. The hubs bolt straight on and the original handbrake drums etc can be used no problems. The shafts are the right length and fit perfectly.

Ive got aftermarket diffs front and rear in my GTR there is no way I could drive it everyday. Turn to tightly and the whole car binds up and comes to a stop at low speeds.

      Oof, I will forevermore have those shredded gears in mind whenever someone talks about showing mechanical sympathy towards their car. Thanks for the photos, fascinating stuff!

      RH9 R32 GTR Build Thread

      The holdups last year were drivetrain related. I had the car out right after getting the bearing issue resolved. Third launch and the car didn't move after releasing the clutch. It had sheared all the engagement teeth off the 1st gear.    Thankfully no other damage was done. I set an aftermarket gear beside an OEM gear and found that the engagement teeth on the OEM gear were much larger and better supported. Looking through my bin of spare transmission gears I found that there are two types of tooth on the OEM first gears - the larger tooth and the smaller tooth. It looks like most aftermarket gearset manufacturers base their design on the smaller tooth. OEM large tooth left - Speedtek, OS Giken, etc or OEM small tooth right Decided to give that larger engagement tooth a try. Pressed the ring off an OEM gear and sent it to a transmission manufacturer here in the States. They did their "faceplating" operation with my synchro ring on the Speedtek gear.   I reassembled it, took it back to the track and promptly destroyed the gear itself.  I'll rebuild this and use it as a spare - thankfully just first gear and the countershaft are damaged beyond repair. Definitely disheartening but my welded on engagement tooth ring held up!  Moved to Speedtek's dog engagement design as the gears appear to be much stronger. So far they have taken much more abuse at the track. Also scored a Stillway lockout from the Netherands for super cheap. It's for some other RB transmission so it took a bit of fabrication to fit but honestly a very easy job. I also had to heavily modify the gates as they were very different.   Then for some reason at the last test and tune a silicon coupler below the throttle blew off and took out the radiator and fan. Thankfully it was in the burnout box and not down track. This car is really beating me up - I still haven't made a pass in it. Ran it through the gears many times on the street but it keeps biting me at the track.  Currently in the process of replacing the radiator and remaking the throttle pipe to remove the coupler and use a cast 90 and a vband. I WILL get this thing down the track...

      Covers most of the above points really. There's a few exceptions but most just see driving as an irritating but necessary task they must complete if they want to get anywhere on time. Also see it as a good time to show their awesome multi-tasking abilities on their mobile and/or doing their makeup.

      I don't believe I posted pictures of the second oil pump pickup I added so here they are. Data shows it gets oil pressure up to the relief pressure much earlier in the RPM. Is that important? Not likely... This was just another attempt to fix the bearing issues.   I also heavily opened up the inlet to the pump since it now had to flow oil from two pickups. I believe the diameter increased about 1/8".
