hi guys/gals

just wondering is it Possible to make a r32 gtr 6speed gearbox for RWD only?

coz i got a r32 GTS-T with a rb26 in it. and it seems that when i drive it it needs a another gear high for the freeway driving. so is there any ways to Modify the GTR box to make it rear wheel drive??

cheers

So it is all ready manual, not 4-speed auto?. If so, you must mean R34 6-speed, as the R32s where only 5-speed. Why not just use a 33 GTS-T box, which would be much easier. But if your heart is set on a 6-speed, you could buy one of the HKS 6-cog gear clusters, which would probably work out about the same price as trying to get the Getrag box out of a BNR34 (not including labour here), while being stronger to boot too. As for the gearbox itself- just have any un-necessary parts removed from the attesa clutch pack and plug up the holes. I've never seen anyone try to cut it off the side of the 'box or any similar mod.

OK, I don't have a RB26DETT in my R32, but it only pulls around 3k rpm on the highway. And that's with a 4.375 diff ratio. The GT-R has a 4.111 ratio, and the GTSt, AFAIK, has a shorter (?, lower number) ratio.

So, how slow do you want the engine to be running at 110 kph?

no, well, not within reasonable cost

mod the R34-GTR box you mean yes?

You know 32/33 5-speed, 34 6-speed.

Want better highway, change the diff to something under tne 4.11 it comes with

Can you even get (decent) after market diffs to fit R200 housings that have ratios below 4.111? Auto diffs are usually taller (ie. numerically lower ratio), but I'm just taking a stab in the dark here. Anyone?

S15 uses R200 (same housing as GTR,etc) and has 3.7 gears (from memory - have to double check but pretty sure that's right). Actually got a set there if your interested - I used the centre from the S15 diff for another project.

      High temp brake fluid?

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣

      Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?

      Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
