i've been told that after around 220rwkw and hard driving, the RB20 box will deteriorate. i never really listen to hearsay about mechanical parts and their strengths, because every car is different.

2 friends of mine (between 150-180rwkw) drive their cars like they're stolen. constant race changes, snapping gears and clutch kicks. their gear boxes have become very very noisy and it sounds almost like they're going to lose a gear any time soon.

i run 210rwkw at the moment, and i drive sane. my box is free of noises and engages all the gears properly.

the RB25DET gearbox is definitely a worthy upgrade if you're going to drive hard, but i'd say just drive till it breaks then worry about replacing or upgrading.

the story goes i got a cheap r32 off a mate cauz he was gonna get locked up if he caught driving i again. the gear box was thrashed but he said it still did third gear burnouts but i need to replace the box. i am not gonna lie i am gonna give it a bit as i get my licence back in 4 weeks after a 27 month suspention i am keen as to burn some rubber. so i just want to know if anyone out there has had a simular problem of a weak box and if anyone has put the r33 box in the r32 and the results. any help on this would be great cheers, jonno

If you plan to thrash it then putting another 32 box in might be cheaper but you will destroy it pretty easy as they are the weakest skyline box.

I would upgrade to the 33 box. Bigger and stronger and less chance of you breaking it again.

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
