ell lets see, pretty much everything in the drivetrain. Lets start at the back of the car and work our way forward to fix them all one by one.
Rear hubs and axles. These things snap like twigs. Went out and found me some r33 skyline axles, which were stronger… they broke both at the same time.
So here is how we fix that. Get a GTR r32 rear diff, axles and hubs. Used 2 shock washers to hold the diff up, due to it lacking the big cross bar on the rear of a GTR. Put all this in. Which unfortainitly lost me my r33 nismo
diff. The stock gtr diff isn't bad, but its nothing like a real LSD locked type. Its better than a viscous, worse than a 2 way. Changed the front flange to put in a 4 bolt type driveshaft. Pretty much was a bolt in procedure. That fixed most of the rear breakage. Bought a 3" tube driveshaft from Driveshafts Unlimited in IL. They did a good job of putting it together, wasn't very happy with the yoke though, it "doesn't look very strong", although I have never broke it, it still scares me. Put some aluminum collars in the rear, to stiffen it up to hold the extra weight I was putting on it. That was pretty much it for the rear. The transmission is a huge problem. SR transmission, well just forget it, you look at it took long it will break. How about a 5 gear cross SR mission from Os giken or other dealers? 500hp max. Then you might as well look elsewhere. So I pulled out the rb r33 rb25 transmission. People "say" it will hold 700 hp in a rear wheel drive car. I say they are wrong. Third gear can strip all the way around. Making it useless. The best suggestion I have found for these, is a r33 with a 3 gear cross. I have not been very impressed with the quality of Route 6 cross. It is not really stronger than stock. An OS 3 gear cross with a os input should pretty much be the answer to your prayers. Another good thing, since your putting out some ponies from this car, is you get to leave it in gear longer. I cannot see these thing breaking under 700-900 hp in a 2 wheel drive car without the car being back halved. You would need near perfect traction to do so. That brings us to the clutch. Which other than the transmission is probably the most expensive piece you will have to buy. Hard choices, you want something that will hold obsene amounts of power and abuse, but but be nice enough your not snapping everything in half. Sort of a tricky subject. No clutch is perfect, so none can really do this, in a street style setup. I have always chosen going faster over breaking some parts that I can find in a junkyard. So I went with a triple. A twin plate will not hold the power I am putting out.
