Branners Posted October 16, 2014 Share Posted October 16, 2014 I read on Facebook the other day that with an adaptor plate you can fit the 350z 6speed getrag. Not heard that mentioned before, anybody else hear of it? The box is about £1000 or something, vs £loadsandloads for an original 2jz 6 speed.

Lee P Posted October 16, 2014 Share Posted October 16, 2014 Yeah can be done and its a strong box as well Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted October 16, 2014 Share Posted October 16, 2014 Plus a custom clutch (and flywheel?), custom propshaft, mounts etc If one of the notorious Supra tuners/garages decided to support this conversion, and offered off the shelf parts and support, I could see it working though.

j_jza80 Posted October 16, 2014 Share Posted October 16, 2014 Also, this conversion would assist 350z owners in changing their rubbish VQ35 engines for something decent Quote Link to comment Share on other sites More sharing options...
Benjy Posted October 16, 2014 Share Posted October 16, 2014 Is this the later 350z box? I've had 2 now that have had internal issues. Input shaft bearings wearing out and 1 of them had shattered a 3rd! Quote Link to comment Share on other sites More sharing options...

Chris Bailey Posted October 16, 2014 Share Posted October 16, 2014 Can hold around 500bhp cant they? Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted October 16, 2014 Share Posted October 16, 2014 Here's something a bit different, a beemer diesel box in an aristo! http://clubaristo.net/forums/showthread.php?23238-94-Jzs147-Single-Turbo-Aristo/page75&highlight=bellhousing Quote Link to comment Share on other sites More sharing options...
Kirk Posted October 16, 2014 Share Posted October 16, 2014 ZF boxes are freaking huge! Some serious beating out of the tunnel would be required to get one of those in a Supra. Quote Link to comment Share on other sites More sharing options...
Branners Posted October 16, 2014 Author Share Posted October 16, 2014 They maintain the box will take 1000bhp, but thats american BHP so lets assume a real world 700. They mostly say it is a better option than the w58. And yes, the later boxes are the ones apparently, just not sure how common the 350z is in the scrap yards of the UK.

Ian. Posted October 17, 2014 Share Posted October 17, 2014 I'm using 350z box & running gear on my conversion. Z box will take 800 hp easy Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 17, 2014 Share Posted October 17, 2014 When someone quotes a transmission capability of whatever HP you know *IMMEDIATELY* they are talking total bull. They are probably newbies, kids, or salesmen. HP has virtually *NOTHING* to do with how long a gearbox will last. It's TORQUE that loads gearboxes. If you could somehow bolt an F1 transmission to a Supra you'd break it almost instantly. They have huge power, sod all torque. So when someone say this box is good for 600 HP you know to stop listening A quick and dirty way to assess torque handling of an unknown gearbox is to look at how big a diameter the gears are (how far apart main and lay shafts are) and how wide the gears are. Shaft spacing and casing length are finite, so "improving" an existing box usually entails deleting the synchro hubs to create a dog box, which allows wider gear width as dogs are a lot more compact than synchro hubs.

Nodalmighty Posted October 17, 2014 Share Posted October 17, 2014 (edited) I was thinking about adapting the Tremec TR6060 to the JZ as an alternative to the GetRag. Tremec rate it to about 700lbs/ft so that is more like 1000lbs/ft in the real world. Can be bought new for £2.2k with a choice of shifter positions.

j_jza80 Posted October 17, 2014 Share Posted October 17, 2014 Isn't the tremec gearbox much larger than the V160 though? Sure I've read that someone on Supraforums tried it, and it wouldn't physically fit in the Supras tunnel. Quote Link to comment Share on other sites More sharing options...

chazuk Posted October 17, 2014 Share Posted October 17, 2014 I have looked into this before you want the getrag from a e46bmw (£450 second hand) its strong lots of turbo'd /supercharged m3's in the states 600hp+ on the stock box Ratios 1st = 4.32:1 2nd = 2.54:1 3rd = 1.62:1 4th = 1.23:1 5th = 1.00:1 6th = 0.83:1 (overdrive) Reverse = 3.75:1 Single turbo'd 6speed e46m3 646whp and 549tq think in a previous video it was a 71mm turbo stock engine not bad [video=youtube;hr-kdrfcO8Q] Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 17, 2014 Share Posted October 17, 2014 Does he miss 5th gear `cos the teeth are in the bottom of the gearbox? All these weird and wonderful hybrids are fine, but given the labour and parts you want something in there that's 100% bullet proof. The Tremec should work, albeit the change is a bit truck like. Most turbo engines do not need 6 ratios behind them, 6th is usually very much an over drive ratio anyway. A 5 speed (or even 4 speed...) box is often stronger as they have a lot more space for 4 or 5 gears than 6. At the end of the day just buying a six speed TT in the first place saves a lot of grief.

HadeS Posted October 17, 2014 Share Posted October 17, 2014 ZF GS6-53DZ 6spd from E60 525/530D biimer is the one which mattsson has in his Supra. 530D has 530nM so the gearbox shoud be strong Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 17, 2014 Share Posted October 17, 2014 Beware gear ratios in diesel sourced boxes. Diesels tend not to rev, so often have a very over driven top gear. Other things you need consider are how to mate it to the engine (!!), input shaft length, spline position and pilot bearing ID, out V input shaft heights, gear lever position. Means of feeding input and output shaft speeds to an ecu if required. Position of rear mount pickup point. Quote Link to comment Share on other sites More sharing options...
Nodalmighty Posted October 17, 2014 Share Posted October 17, 2014 The Tremec should work, albeit the change is a bit truck like. The TR6060 is a vast improvment over the TKO and T56 boxes. Quote Link to comment Share on other sites More sharing options...

coza Posted October 17, 2014 Share Posted October 17, 2014 Hi I was thinking that but for a z33 box conversion you will need to consider. transmission plate. bellhousing maching to achieve spigot depth mainshaft machining or custom spigot bearing. prop custom shifter speedo sensor signal correction. diff ratio clutch centre. it is not a 5minute job. And certainly shouldn't be undertaken by the inexperienced. Quote Link to comment Share on other sites More sharing options...

Paul Whiffin Posted October 18, 2014 Share Posted October 18, 2014 I was looking at this myself but I don't think it's that's viable price wise. When you factor in all of the conversion parts needed it soon starts adding up and before you know it you are over 2k just for the gearbox, conversion parts, flywheel/clutch and that's not including custom made rear gearbox mount, modified Propshaft, doing whatever needs doing for the gearlever. And then if you want to convert from auto to manual you still need to find the pedal box and master cylinder. Quote Link to comment Share on other sites More sharing options...
Nodalmighty Posted October 21, 2014 Share Posted October 21, 2014 (edited) http://www.nod-land.co.uk/ForumStuff/LS2inSupra.jpg Here is a LS2 into a MK4 on a Tremec T56 6 speed that Craig at Dyno Torque did quite a while ago. He doesn't remember having to do any beating of the trans tunnel to get it to fit. TR6060 is not much bigger if at all. He did say if a fitting issue did occurr it would be the bell housing as these are bigger on the Chevy. However, if using a 2JZ Auto Bell housing with an adaptor plate this shouldn't be an issue.
