Rb26>rb25

[monga]

What are the major differences in the rb26 box against the 25? strenght wise ect?

The 26s are double sync but the 25s are not? im unsure

Thanks.

They are identical save for the transfer case

25's are double synchro just like the 26, both boxes use the same synchro's, bearings, rings, etc

internally the only visual difference i saw was the input/main shaft looks a little different, 26 is thicker in some places, i've been told that the gears are the same as well...

there may be other little differences but basically the same,

25 boxes are very rare these days, drifter love em, so you could probably buy a 26 box and change to internals over to the busted 25 box, was considering this recently but decided against it, by part numbers most parts are the same but making parts fit is a different story...

has any1 tried this? ive heard a few but no one willing to share secrets

There are plenty of boxes around.

Its just people arent prepared to pay the asking price for em

But GTR boxes go for almost the same as RB25 boxes anyhow. Usually only $100-$150 in it

Where are they, looking for one atm and would pay upto 2k for a really good one!

Thanks

about a month or 2 ago when i was searching....

Sydney wreckers were asking $2000, Brisbane $1500... no stock in both states!!!

found a R33 GTR box in Brisbane was $1000... with warranty!!!

also found a lot of ppl trying to pass rb20det boxes and rb25de boxes off as r33 turbo boxes so be careful

Thanks for the info, guess ill go a gtr box as a last resort. Was there much modding it to make it suit RWD.

Cheers

The z32 vg30 boxes are the same also..i put one on my rb30det..just got the front (bell) section off a broken rb26 box and bolted it on.rear extension housing is a bit shorter but a rb25 one will go on if you want,i didnt bother im just using the vg30 one.Im making over 500rwhp and havnt had a problem.EKW in melb sell vg30 boxes for $550.

Thats a hot tip id forgotten about.

So they are the same strength as r33 and gtr boxes?

thanks mate

[rbs30]

yeah exactly the same box..I've run full slicks on mine and launched it pretty hard and ive never had a problem.Admittedly ther would be a bit less stress on it because its in a fairly light 240z but i cant see it breaking..Same part code as rb25/26 boxes

[Gts-t]

hmm thats very interesting

did they have much stock? what year box did u get ?

[rbs30]

They had a few at the time but that was over 6 months ago..not sure what year,they are all the same as long as its from a z32.Also i got one out of a na because they are both the same and i figured the the turbo ones would have copped more of a hard time than the na.

Ok thanks alot for the help, ill see what a few other people think about this.

Not that i doubt yours is holding up well it just seems a little to good to be true

Cheers

[rbs30]

LOL.fair enough.

think i remember seeing brand new 25 boxes for 3500.. id much rather buy new than pay 2grand for a 2nd hand one that is 'supposedly' good condition!

also i have a 25 box with GTR internals but i didnt do the swap myself so i dont know if there are any complications regarding swapping. Seeing as the OS cross mission set drops straight into either box, id say it would be straightforward?

I've been offered GTR boxes for $800. Is it impossible to get the angle grinder out and cut sick? I've never looked at one so may be completely off the planet here.
