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.

Not good news mate!

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.

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.

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.

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.

But the cost of a whole new gear-box is just frightening. (Was just quoted $14,500+GST+Fitting)

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

Good luck on your search mate

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?

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.

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. (Stupid R34 GTR's)

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 ..

hey snowy y dont u go a hks 6 speed fron japan they are preety cheap compared the price you where quoted form nissan for the box

cya mate

no he didnt.

He got the stock one rebuilt/fixed.

he is in Canada for a few more days yet :cheers:

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.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
