im building a custom car with a r33 GTR powertrain and a full built rb26 check out my other 2 threads to see what im building and spec. My question is how should i go about building a very strong drive line. Im planning on a exedy twin clutch, all axles and drive shaft are custom built buy driveshaft.com and can handle more power then ill ever have. the rear diff is a stock r32 gtr lsd ill have the LSD rebuilt. the front diff is stock and ill be puting in a LSD. Now the center diff how strong is it ? is there a up grade kit or something that im not aware of? and the transmission i heard that 3rd gear is weak so is there a trany upgrade kit to fix this or do i just have to bit the bullet and buy a race trans like OS Giken? I do have a great transmission builder so a up grade would be no problem. Ill just be smooth on the powertrain till its fully upgraded but i want to be able to run it hard on the track with slick mainly race track but some drag racing. any help or advice with this would be great and if there are some treads i have not read please sent me links Thanks

You can get gearsets from PPG, PAR, Hollinger, OS Giken, etc.

You can get Quaife and Nismo front LSD.

No idea on centre diff, but I'm guessing you'll be running oil coolers for diffs and gearbox?

Grab a Hollinger 6 speed sequential :D

Auto Gallery Yokohama gearsets (rebuilt boxes)....


these guys in Japan do stronger gearsets and transfer boxes.



Also possibly Dodsons in Auckland NZ for transfer case.

Am I missing something?

GTR's don't run a centre diff unless you're building a special transfer case using parts from some constant 4WD?

That's the thing... They don't, as you know. :D

Always helps to know the basic mechanics of the car you are building before you go asking for quotes.. I'm sure any workshop would be happy to charge for a 'centre diff' and the send you some metal in a box.

Try this, google the difference between a centre diff and a transfer case. These guys know the car mate, it's clear your mechanical knowledge is a little way behind theirs. As for "bomb proofing" a gtr powertrain, put at least 40k aside. That's if you want to really do it properly. Lonefield billet cv's, billet driveshafts, carbon props hafts, hollinger sequential gearbox, quaife diffs front and rear, gts4 crown wheel and pinions, modified sump and front diff housing. Then you need to look at clutches, it gets out of control as while you make one thing stronger it creates another weak link in the chain.

There is GENUINELY bomb proofing as you say, then there is sensible strengthening of components

if $$$ is not a problem sure knock yourself out but if $$$ is not infinite, then maybe u should plan on reasonable upgrades. Why pay for a part that can take 2000hp when u will only ever have 1000hp unless of course the price is the same then by all means.

u can make a car fast and reliable without spending exorbitant amounts of $$... :)

Pretty big difference between a transfer case and a diff!

To do it on the cheap, properly, you're still looking at least 12k in diffs, clutch, transfer case, gearbox.

That's not taking into account axles, driveshaft or anything else.

      From there, as the manual says....assembly is the reverse of disassembly, no tricks worth mentioning Much better (for me)

      In my case, the standard wheel I had was in good condition but the buttons had more wear, so I swapped them across from the original wheel from the car. The plastic rear cover is held on by 4 tabs, and once the wiring is removed you can get access to 2 screws on each side the hold the buttons in From there I just swapped the wiring over. What was interesting is the standard style wheel is 2.0kg but the carbon fibre one is 50% heavier at 2.9kg. It even has a weight inside the wheel at the top to make up for some sort of imbalance in the design. weird

      Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller

      So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stomp on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off
