start to notice grinding noise when changing gears and eventually BANG.... The gearbox goes on holidays and wont come back until you rebuild or buy a new one.

Just be gentle with the gearbox don't slam it into gear all the time. Change slowly and it will last alot longer

nothings invincible. I have been through 4 gearboxes in my old R31 skyline. though they aint built like the rb25det gearbox. Just don't flat change and always try and wait for the synchro's to mesh and you shouldn't have a problem at all. In terms of strength they are pretty strong but its the synchros which wear out and start to grind. After they were out enough the wear moves to the actual gears (this would be metal deposits left on magnetic gearbox drain plug)

your synchros may be starting to wear and you just try and change gears to quick for them. My gearbox had a grind into 4th no matter how slow or fast you were going. Its quite common that 4th gear synchro grinds in an r33 box as they wear the fastest.

      There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)

      What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).

      No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here.

      I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
