dave32gtr Posted August 23, 2008 Share Posted August 23, 2008 Just thougt I would find out who has broken a gear box. What happened (striped 3rd). How much horse power did you have. What sort of box did you have (32, 33, 34, stock, aftermarket), etc. Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/ Share on other sites More sharing options...

Stock GTR Posted August 23, 2008 Share Posted August 23, 2008 I think most people will agree that a gearbox is like a clutch. It really depends how you treat it. So far iv'e had no problems with a stock 5 speed box and similar power levels. However, when I take the car to the track it may be a different story. I know the stock boxes tend to let go in 3rd but sometimes this can be attributed to harsh clutches and particular brands. I am also interested in feedback from people using these aftermarket gearsets.

Piggaz Posted August 23, 2008 Share Posted August 23, 2008 ^^ When my box let go I was giving it a hard time (8000 rpm change from 2nd to 3rd) but knowing that 3rd is a weak point i was always very tip toey into 3rd, this gear change being no exception. Clutch is a Nismo twin plate coppermix which may or may not have helped but atleast it has a sprung centre.

GTRsean Posted August 23, 2008 Share Posted August 23, 2008 R32 GTR, 3 years ago when it had 400hp atw stripped 3rd gear when shifting from 2nd, felt weird sloting (worn synchros?) in for a split second then bang, had os triple plate. Also snapped a uas pivot ball a few months ago. If money is no problem then I'd will/would go an os, ppg gearset to handle the hp.

R33GTRKid Posted August 26, 2008 Share Posted August 26, 2008 is it true that in the series 3 R33 GTR they upgraded third gear strength? Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/#findComment-4091614 Share on other sites More sharing options...
GTRsean Posted August 26, 2008 Share Posted August 26, 2008 is it true that in the series 3 R33 GTR they upgraded third gear strength? I heard something like that, but it's more of the synchro design they improved.

Syncros going The OSG 5 Speed kit is going in as we speak-there is a thread in this sub forum.

allblitz Posted August 26, 2008 Share Posted August 26, 2008 Been through 3 gearboxes on my GTR, 800hp (440kw at all 4). Has an OS Giken Gearset in there now. Handling it beautifully.

(OO)SKYLINE(OO) Posted August 27, 2008 Share Posted August 27, 2008 From memory a standard GTR gear box can take up to 500kW but all depending how you shift gears and how well you treat it. I think a Getrag 6 speed would be quite good and I was told a Holinger 6 Speed was real tuff.

Kranker Posted August 27, 2008 Share Posted August 27, 2008 Dont think that a Getrag 6 speed (r34 'box) is really the answer, if ur breaking GTR 5 spds, then ull prob break the Getrag 6 speed If i had one and it broke, id be looking at the OS Giken gearsets, either the 1-3 or 1-5, or go Aussie made and go for a PPG gearset.

(OO)SKYLINE(OO) Posted August 27, 2008 Share Posted August 27, 2008 ^^ Yeah right, just from reading, the OS Giken Gear Sets look like the answer. Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/#findComment-4094441 Share on other sites More sharing options...
Stock GTR Posted August 27, 2008 Share Posted August 27, 2008 Yeah, I too thought about the 6 speed from R34's. The ratios of gears 1-4 are closer and seem to handle more power. However it also means changing the diff gears to suit the gearbox. Much cheaper option will be an aftermarket gearset.

Mr. Keets Posted September 1, 2008 Share Posted September 1, 2008 I looked at the Getrag as an option but in the end I went for the OSG kit...from what I could gather the Getrag GB rebuild was a pricey endeavour. As for a standard box with 500Kw..I suppose you can put any Kw through a box is you baby it. I would think 400AWKw would wear a 32-33 box out pretty quickly if driven with any verve Link to comment https://www.sau.com.au/forums/topic/233041-gtr-gear-box-strenth/#findComment-4104304 Share on other sites More sharing options...
dave32gtr Posted September 2, 2008 Author Share Posted September 2, 2008 One of my friends had a Trust gear set in his 32. He use to race the car. He liked the gear set, said it took him a while to get use to it, but the harder you changed gears the better it was. Don't know what it would be like for a street car though.
