I think you might be surprised as to how much difference there is between the two gearboxes. Don't forget the S15 has a turbo, so the torque output is pretty high.

Nevertheless, I would vote for the Z car box over the S15 box. I mean, people with S15s were famously replacing the 6 speeders with 5 speeders because the little SR20 5 speeder was stronger.

Maybe, I am not really familiar with the s15 boxes. But my observations have always been that gearboxes suffer the most stress and damage when they are suddenly shocked with lots of torque in a small space of time. The sr20 engine doesn't really fit into this category, even with a turbo. Sure torque output on an turbo s15 can be high, but its usually up high and once the clutch engages and everything starts building momentum the stress on components is much more linear and manageable.

Driving like an idiot is not accounted for of-course. That's why you get lots of broken drive train components and mounts because people are dumping the clutch on wide after-market wheels with grippy tires and high output engines on cars that were never designed to handle that kind of abuse.

Will a 350z box Bolton the R34gtt though also are they any stronger than Rb25 boxes. Could be a good mod for economy and possibly higher speeds.

And no it won't bolt on. Assuming that they are common with the big frame Nissan 5 speeders (big assumption, almost certainly wrong), you have to build up a box using appropriate front and rear halves. Otherwise you're into the territory of using adapter plates. I'm pretty sure that this is how it has to be done. Plenty of VQ into R chassis conversions using the original R chassis gearbox have been documented with adapter plates, and I don't think I've ever heard of someone Frankensteining two halves of the different gearboxes together.

Frankensteining can be done with VG gearboxes, because only the bellhousing half of the box is different.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
