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

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.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?
