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.

      R34 Skyline climate control unit transistor

      By sinn3r · Posted

      perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
