ive been hearing all sorts of different mumbo as to how much these boxes can handle. Im aware thats its more the torque that destroys them then power. What power are people running/had running before their's let go? 2wd/4wd/application?

4wd does put alot more stress through the gearbox, but people tend to break 3rd gear, and for most cars traction at 3rd gear speeds isnt usually a problem.

Ive got a feelling that there was an actual design problem with the allignment of 3rd gear, selector and gear dont match up 100% or something similar...dont qoute me.

So smashing the box through the gears tend to kill it. Try and avoid very hard and fast changes into 3rd gear, both from 4th and from 2nd, and there is a fair chance she'll hold together.

If it does break id be looking at aa PPG or OS Giken gear set, they dont cost the world and from what ive read are pretty tough stuff

[GT51R] was driving around with a 500+awhp r33 gtr with a t51r turbo and it lasted the punishment, and thats with a huge turbo coming on hard n fast.

Plenty of other boys as mentioned with big hp on stock boxes, i wont be overly worried but i would always have a couple of grand aside just incase it did let go

1.47 60 FOOT 10.4 AT 132MPH ON A COMPLETELY STOCK RB30 BOTTOM END SORRY BUT THATS RIGTH I CANT DRIVE

LOL! Stop driving like a psychopath on the street and they wont break as quick. You're an animal!! :sweat:

:P:)

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
