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.

      R32 GTS (RB20DE) Injectors Replacement

      By joshuaho96 · Posted

      Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs.

      This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
