Gtr Gearboxes

[ZILR-34]

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?

[sh@un]

Will probably only drop 300-400 rpm with the 6er anyway, as the ratios on 2, 3, 4 and 5 are a lot tighter, with 6th being similar to 5th on the earlier boxes.

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.

Stagea is 4.083

[sh@un]

Seems JETR32 has lost interest anyway.

the only reason im saying dis is bcoz i got 4.111 diff ratio. but it it seems to much work and money to slam in a 6speed ill stay wit the r33box..

thanks for ur output guys

cheers

way too much trouble to change the gearbox, of you want lower revs you want a lower ratio.

And the ratio is defined by the crown and pinion gears which normally come with the casing not the centre
