Gtr Gearbox?

[STOCKGTR]

Has anyone in Vic done any mods to their GTR gearbox? I busted 3rd synchro on the weekend and am trying to find out what is the best thing to do while I have the box out?

Labour won't cost me so I will save there but I do need a clutch also, so buying a dog gearset is most likely out of the question, just too much $$$$ at once to spend.

Has anyone heard of stronger aftermarket synchro's??? Where?

Thanks.

No real budget as yet. Just trying to see what is good value for money. I haven't even decided which clutch to go for. Tossing up between OS twin or Exeddy Twin.

I think I will most likely just replace synchros in 2nd, 3rd and 4th. Was thinking of getting short shifter, but have heard bad stories.

Waits for Chris and Ferni's comments on the twins

Ring him and discuss pricing vs what you want.

Just have the box rebuilt for stock if you ask me.

Unless your over 400rwkw i wouldnt be worrying about gearsets or anything

Thanks for that. I will give him a call. Though I'm a bit reluctant to use another single plate... The Exeddy 3 puck I have was pretty hopless, slipped from day one.

The reason I would like an aftermarket gearset is not the strength but the fact that they are closer ratios.

Jim is the man. Trust me

As for ratio's... just change the diff's to 32 GTR diffs

Cool will give Jim a call. As for the diff I have just fully rebuilt the rear so I won't be getting rid of that anytime soon

Anyone run a short shifter in a GTR? What do you think of it for the track?

Jim Berry clutches are the shinitz. No doubt about it. JB FTW!!!

As for the gearbox, if you are running <400rwkw, stock box is fine. After that, I highly recommend the OS Giken Cross Mission gearset. Get the sandwhich billet plate and upgraded input shaft for peace of mind.

This combination in my car has held 600+ awkw with no problems whatsoever.

my car must be 600rwkw!

Breaking gears due to excessive power and wearing a syncrho ring out are two differant things. As I have mentioned previously, I am considering an after market gearset not for the strength reason but for the better response the shorter ratios give .eg mines car has R33 diff and aftermarket gearset.

As for Jim Berry, looks like he is the man by an overwhelming number.

Thanks guys much appreciated.

god you're a moron...

[phunky_monkey]

I've heard mixed reports on the OS Giken Leewah... so you're a fan?? And it's still holding up well??

I was considering one for my car, but don't want to fork out 4k+ and have it break on me...

Heaps of people using it.

Bens GTR has one aswelll if im not mistaken. Cant argue with the results of that car

But Ben is using "his own" style of clutch?

OS gearset is the way to go.......if you have the cash.

I've contemplated it in the long run, but I always figured just whcking in stock boxes was the way to go... but I guess it depends on how big the trail of stock boxes behind you gets...

Thats true, but apart fom the strength aspect of the OS gearset, the added respone you get from the closer ratios is awesome.

I've seen a GTR with the trust gearset and that thing got from 1st to 3rd in no time
