Transfer Case Modification "extra Clutchs"

My 32 gtr seems to really tail happy and I was wondering if anybody out there has done the modification to the transfer case where you add another clutch to lock it all up. I have a spare case and I was considering splitting both of the cases and build up one with the extra cluch to hopefully drive the front wheels a little faster so the car is more balanced when I gas it out of corners because at the moment the car just seems to oversteer and not four wheel drift/ drive hard out of the corner. There is drive to the front wheels but I want more. The engine and gearbox are out of the car next week so I thought I might give it a go. I have read bad things about the electronic controllers so I don't really want to go there.

If people with any experiance with this mod could help me out it would be much appriciated.

I have rebuilt a transfere case but never added extra clutches, I guess it can be done but I would be a little worried about not getting it right and the clutches wearing out due to contacting each other all the time. There isnt alot of room in their so make sure if you do it measure everything carefully to make there is enough ample room to allow for it. I just rebuilt mine with all new clutch plates and seals as the other where pretty worn and the gearbox I did it on only had a genuine 100k on it and never had a great deal of power so I would hate to see some of the thrashed ones...

Hope this helps!!!

Don't you mean CRD's Jap mechanic, or does he work for you direct now?

Our tuner is Jim Souvas....or can't that be right either....cause he works for CRD.

If you were at the last drag day you would have seen both of these guys crawling over our car doing all the necessary tweaks....and on a Sunday too.........

You really need to spend less time on your keyboard and more time at the track!

Does anybody know of any skylines that have been modded by ben?

Gareth, heaps of people. Probably all, if not most of the track GTR's that come out of his workshop have been tinkered in varying ways and this is one of the mods.

Fair enough too if he wouldnt let out openly what is done. Give him a call and see what you can organise B)

From what i can translate from Tom it involves removing the thick clutch plates from the transfer case and replacing them with more thin ones. this gives the plates in the transfer clutch more surface area and stops/reduces clutch plate slippage.....much like a multi plate engine clutch.

After all this time I have the g/box out and the transfer case ready to be pulled apart. Waiting on buying a torx bit (Also go the g/box out in 1.5 hours a new record for me). I hope by reading the manual that if I measure the shim at the end of the retaining plate and the retaining ring I can see how much wear there is before I start or I can measure the thickness whilest its apart. It is not a big job pulling it apart by what I have read. Hopefully I will know by tomorrow night. Looking at the shim sizes there is like a few of you have said not a lot of space in there. I just find it wierd how one of my gtr's pulls around corners with the front and the other doesn't. Maybe I should have bleed the system and checked the diagnostics before I pulled it apart. I now have three transfer cases in my hands so I might just pick the one with the best lot of clutch's if I can't squeeze one more in there. I will let you all know shortly.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      On 12th June, the mechanic could not figure out what the issue was, but the car seems to be flooding with fuel. He was suspecting the tune, thus referred me to a tuner. Although the tuner is not familiar with Nistune, last Monday (30th June), he came over to try and re-map it. Despite the tuner trying to completely stop fuel, it kept sounding like it was pushing fuel. Tuner ended up suspecting either the ECU or Injectors. I do not believe the ECU or Nistune is the issue, as the Nistune software reads and communicates properly. Today, I removed the (new) injectors to see if they are clogged or leaking. Surprisingly enough, after those 3 days of driving, injectors 2 and 3 look very blocked. You can see the difference in the picture. I blew a bit on 3, that is why it doesn't look as clogged as 2. I am still unsure if this is what is causing the no start issue, but I am now feeling that I may have bought the injectors and Nistune without the need to do so, as the problem seems to be coming from somewhere else.

      R34 GTR Front Diffuser/Guard Liner questions.

      By Kinkstaah · Posted

      Hello everyone. I've recently started the research into R34 GTR front bits and running into eye watering prices. On the plus site it looks like some places make 'replacement' fender liners for these cars. At eye-watering-but-less than stock prices. I also noticed there's plenty of diffuser options available too. What I would like to know is if my following assumptions are correct. 1) The OEM guard liners are actually only 'half' the liner. They go together with the OEM brake vents which are a separate item which looks to be quite a large 'panel' that is part of the liner. The GTR bumper has bolt holes along the front. I assume the ones in the vent correspond to the ones the OEM liner does not have (circled?)   2) The V-Spec front diffuser supplants the brake ducts in the above item. I am assuming these still work with the guard liners as there's no alternate part that I'm aware of. I don't see how they go together, so I'm making the assumption that they have to, somehow. I know the center splash guard is different on the V-Spec (and is the price of the damn diffuser alone). How does the liner interact with this? 3) There's alternate front diffusers that do away with it all. Annoyingly, a lot of the clones and CF different ones... have no brake ducts on them. I like the idea of them though. My brakes get hot on the track. These alternate diffusers are a lot cheaper than plastic splash guards. I'm assuming you don't have to/aren't supposed to remove guard liners to run a diffuser. I suspect that quite a few people actually do not run the guard liner because with a front undertray you're getting a lot of 'splash' guarding anyway, and most people remove liners given they're probably running a pretty aggressive setup with a diffuser at the front. It would also be nice to know if anyone has ever run the 'reproduction' guard liners and know whether the fitment is OEM quality or "OEM Quality". Example: https://www.ebay.com.au/itm/356254671561 https://carbonetics.net/products/nissan-skyline-r34-gtr-plastic-front-wheel-arch-set Is this knowledge still around?
