Snowman Posted May 24, 2004 Share Posted May 24, 2004 Yesterday I managed to break my 3rd gear synchro in my R34 GTR Getrag 6 Speed. Now I know that Nissan have not provided any spares to be available with the Getrag box. But the cost of a whole new gear-box is just frightening. (Was just quoted $14,500+GST+Fitting) Does anyone know of where I could possibly source parts for these boxes? I have heard that possibly the parts are interchangable with the 6 speed made for the BMW - can anyone confirm this? I know this is the 3rd R34 with broken synchro problems (2 3rd gears and one 4th gear) that I have heard of so surely they haven't all had to replace the whole gearbox! Any help you be appreciated.

Are you saying Nissan cant supply any components for 6 speed box or Nissan Aust dont stock them? The earlier 5 speed boxes are getrag and all parts are still available through Nissan.

meshmesh Posted May 24, 2004 Share Posted May 24, 2004 Andrew, Just got of the phone with a mate who's just shipped in a sh!tload of parts. He doesn't have a 6speed, but has around 10GTR 5speed boxes @$1200, which we think should bolt on directly? Did you speak to ICE, or Dean?? I'm wondering if the parts from the GTR 5 Speed boxes fit the Getrag boxes, maybe you could do a swap. Ultimately I think Leewah has your answer in a reply to one of my question in another thread all about gearboxes.. he recommended speaking to Frank Modena of Modena Engineering in Melbourne.

Snowman Posted May 24, 2004 Author Share Posted May 24, 2004 Yeah I know I can put a 33 box in but Id rather not go to a 5 speed. But Nissan Japan did not have spares available for the 6 speed getrag box. I believe that there are some companies in Japan that have made spares for this box but I dont know who they are! So I was hoping that someone might know. Been to Ice - they are looking further as well. Spoke to Dean - doesnt have one but can get boxes for around the $4K mark. Troy (ylwgtr) has a mate with a secondhand box for sale too apparently. But Ideally I'd like to fix it - even strengthen it whilst at it cause apparently this is a common weakness.

benjiman74 Posted May 24, 2004 Share Posted May 24, 2004 Yeah, dont go to the 5 speed you'll have the added hassle of changing the diff ratio etc. I'm told holden now have a 6 speed getrag that is going behind the new quad cam v6. I dont know if the parts are interchangable with the r34 box but it may be worth looking into along with the bmw getrag's you mentioned earlier.

meggala Posted May 24, 2004 Share Posted May 24, 2004 sad to hear snow man the might getrag is not so might. seeing as you are condiering a considerable up grade might pay you to consider swaping back to a 5 speed with an osgiken gear set. http://www.otomoto.com.au/ btw were you flat shifting Link to comment https://www.sau.com.au/forums/topic/41716-getrag-6-speed-box-problems/#findComment-854330 Share on other sites More sharing options...

I've always thought that going from 2nd to 3rd in my car isn't as smooth as all other gear changes. Oh well.

Amaru Posted May 24, 2004 Share Posted May 24, 2004 Ive heard rumors the 6 speed Getrag in the GTR is almost identical to the Supra Getrag box, witht he addition of a transfer case. I dont know how true this is or not, maybe see if you can find out, and then see if any of the supra guys know where to get bits from?

R33NT Posted May 24, 2004 Share Posted May 24, 2004 Read about pfitzner or something like it in one of the HPI mags. Just checked out their website and they say they will cut gears to you spec. I dont know how cost effective it will be but it couldnt hurt to call them. I seem to remember them offering a full gear set for GTRs and they said that most people are willing to break several gear boxes before they final see the advantage in buying a dog box. http://www.gearbox-racing.com/ Link to comment https://www.sau.com.au/forums/topic/41716-getrag-6-speed-box-problems/#findComment-854705 Share on other sites More sharing options...
judd Posted May 25, 2004 Share Posted May 25, 2004 I am able to source the Nismo Gearset for this box this should answer all your problems. and much less than what you think. please email me juurift@yahoo.com.au Link to comment https://www.sau.com.au/forums/topic/41716-getrag-6-speed-box-problems/#findComment-855698 Share on other sites More sharing options...
Snowman Posted May 25, 2004 Author Share Posted May 25, 2004 Ok - I broke it on a track day at Sandown. Not sure if it was done going from 2nd - 3rd on the main straight or from 5th-3rd at turn one. Didnt pay attention to when it first happened as it feels the same as if you just try and change gears without pushing the clutch all the way in which we have all done - so initially I just thought thats what Id done. It was only after a lap or so that I realised it wasn't me not clutching proplerly but infact the synchro was farked. Anyways - thanks for all the help. Im not going to go back to a 5 speed. I dont really want to put a secondhand box in at as I have also found a few people with pulled apart boxes who would be willing to sell parts - but they have also turned out to have busted or already missing 3rd gear synchros! So I now have a quote to get the parts machined up by a local mod at a much better price then even a secondhand whole box - but am also getting quotes from both pfitzner and holinger on strengthend dog rings. BTW - clarkey - dont panic mate - the cost of the 33 gearbox its very very tame in comparison.

Maxi_z Posted December 27, 2004 Share Posted December 27, 2004 I have also the 3rd gear syncro to change on my R34 GTR vspec, did you find out where to get new ones or stronger ones? What other parts could be changed to make the gearbox stronger?

Cameron_Datto Posted December 27, 2004 Share Posted December 27, 2004 I think The WHITEs that came 2 outright in Targa Tas in there GTR made there own syncros ... you can Not buy all the parts in a BMW Getrag 6 speed as they only list certain parts in the box 4 sale .. other wise a exchange box from Bmw .. Getrag rate there boxes as the Maximum inputshaft torque in newton meters the box can take safely .. So not all Gearboxs with the Name Getrag are the Same ..

tomj Posted December 27, 2004 Share Posted December 27, 2004 They are definitely not the same neither will the new holden 6 speed. Getrag is a brand not a model, remember that. as for parts. a 6 speed sequential box from hollinger would only cost you a little more... while a gear set will cost you alot less Link to comment https://www.sau.com.au/forums/topic/41716-getrag-6-speed-box-problems/#findComment-1137613 Share on other sites More sharing options...

Snowman Posted December 28, 2004 Author Share Posted December 28, 2004 The R34 box is identiacal to the Supra TT (minus the transfer case obviously). All my parts came from Toyota. And I did all the synchro's, 2nd, 3rd, 4th gears, the 1st-2nd and 3-4th shift drums plus the slide sleeves. Most parts are readily available from Toyota Australia. Troy (ylwgtr2) recently rebuilt his box himself and is helping me (aka - doing 99%) of mine currently. Well at least I hope he is. LOL.
