JimC Posted December 30, 2014 Share Posted December 30, 2014 Hi All So if I could get copies of the back plates made how many people would be interested? Regards James Link to comment Share on other sites More sharing options...
GT6 Nick Posted December 30, 2014 Share Posted December 30, 2014 Jim, Steve has now commissioned a batch - see 'The r160 scooby diff project' thread. Link to comment Share on other sites More sharing options...
JimC Posted December 30, 2014 Share Posted December 30, 2014 The guy I used to cut the front plate and the spring plate still has the drawings so I might be able to get more cut but the folding of them might be harder as I do not have access to the folder I used, but the guy who cuts them might be able to help with this. I have attached pictures of the back plate I made, it now has the plugs drill and tapped. James Link to comment Share on other sites More sharing options...

humber172 Posted January 19, 2015 Share Posted January 19, 2015 What stops the halfshafts comeing out under sideways stress from the swing spring setup ? Link to comment Share on other sites More sharing options...
esxefi Posted January 20, 2015 Share Posted January 20, 2015 snaprings or 'c' clips if you are referring to the triumph diff. I can't see any diff would suffer failure from lateral stress on a spitfire considering most have a high bearing preload on the carrier/output shaft as designed.

humber172 Posted January 20, 2015 Share Posted January 20, 2015 Sorry I wasn't clear what I meant was can the Subaru diff conversion only be used with a mk2 vetesse type rear suspension setup Link to comment Share on other sites More sharing options...
Nick Jones Posted January 20, 2015 Share Posted January 20, 2015 As they come from the common, modern Subaru applications, the driveshaft will simply pull out with a sharp tug. This does mean that they are only suitable for a suspension layout where cornering loads are taken by the wheel bearing rather rather than diff side bearing. So yes, Roto flex layout as Mk2 Vitesse/GT6 2 and early 3 is suited. Swing axle cars, not. There are variants of the diff around (mostly dating back 30 years or more AFAIK), from cars such as Datsun 510 or 240Z which have flanges attached and could be used with swing axles. They'll take some finding now though. Nick Link to comment Share on other sites More sharing options...

Spit131 Posted January 21, 2015 Share Posted January 21, 2015 The seperate stubs are held in with an external circlip rather than a snap ring . Shafts are then pinned to these . M Link to comment Share on other sites More sharing options...
humber172 Posted January 21, 2015 Share Posted January 21, 2015 Where would I get hold of them ? And would they allow me to convert to a newer diff ? Link to comment Share on other sites More sharing options...
humber172 Posted January 21, 2015 Share Posted January 21, 2015 Also do you think a standard ( re built ) 1500 would pull a 4.44 diff ( I'm only considering this as the diff currently in it is noisy so will need replacing anyway) thanks Ryan Link to comment Share on other sites More sharing options...
Spit131 Posted January 21, 2015 Share Posted January 21, 2015 I can't imagine they will be that easy to find in decent condition but there are some major Subaru breakers about on eBay etc , shelves full of S/H diffs and shafts so you might be lucky . I think this type of diff/shaft went out of use some time ago on the rear end so not so new and I could not tell you what ratio diff's ran this system or which vehicles . As I have said , Subaru model/parts is not easy to figure out . Could be easier to go a different route ? Link to comment Share on other sites More sharing options...
esxefi Posted January 21, 2015 Share Posted January 21, 2015 why not the ford route. the larger engine sierra diffs come with the same shaft retaining principle as those above shafts plus comes with bolt on cv type flanges. my only concern is that there is not a lot of material behind the circlip and when being used in the way as being discussed with swing axles the continuous back and forth thrust may fatigue the small ring of splines which could break off(something you don't want floating inside the diff is small pieces of hardened steel). good range of ratios and fairly common.

Spit131 Posted January 21, 2015 Share Posted January 21, 2015 (edited) Have to agree with you esxefi , I don't think these were designed for such an application . There are companies ( Beta Motorsport/Wolf Creek racing ) however who will sell pairs of stub axles for these r160 diffs with the Datsun CV attachment plate but you are looking at stupid money and the same question remains . Sorry having seen the picture I am loading I see the spline/spigot is different but gives an idea for example . Thinking about it surely the shafts would need a chamfered bearing to be suitable , clearly a circlip would not be sufficient for any degree of pull resistance . Sorry again but not something I have ever had to think about before . Also you will then have the issue of mating your outer CV , no ? Must be easier options .

Bobbyspit1 Posted April 11, 2015 Share Posted April 11, 2015 Silly question ? The scooby rear diff has been done before, what driveshaft set up was used in those? Rob Link to comment Share on other sites More sharing options...

GT6_sleeper Posted May 12, 2015 Share Posted May 12, 2015 Just wondering, Is there a reason the Subaru diff has been selected over others? Just spent a bit of time on ebay and why not something like the 350z diffs? better ratios and a LSD diff can be had for less than £150 some going less than £100. Just a thought but i guess a carry plate can be made to adapt this to the triumph small chassis and an off centre rear diff plate machined to match the original mountings?

Nick Jones Posted May 12, 2015 Share Posted May 12, 2015 Size. The 350Z / 200SX / Supra diffs are big. No way to retain the transverse leaf. But you are right, there are other options. Sierra (getting harder to find now though) and a whole tribe of BMW ones to name but two families. I think the Subaru choice is down to Rocky's use (and thorough documentation) of the Datsun 510 kit years ago. Nick Link to comment Share on other sites More sharing options...
GT6_sleeper Posted May 12, 2015 Share Posted May 12, 2015 (edited) Cheers Nick, going to compile a list of modern rear diff sizes that could take an adapter to fit. May look at something like this and scrap the spring. I don't like a couple of things about this such as how this one uses the original Rotoflex lower wishbone I would look at something that would have two chassis mounting points and it should be adjustable also look at the arc of the top locating arm keep it fixed not adjustable and a little bit beefed to take braking force and what not. Does anyone know if the shock tower is upto the job of taking a coil over or should it be strengthened? If anyone has any diff dimensions please can you share. Just for reference this will be nothing I will be selling once done but happy to share any cad drawings for plates that are done to take to your own machine shop Edited May 12, 2015 by GT6_sleeper Link to comment Share on other sites More sharing options...
esxefi Posted May 12, 2015 Share Posted May 12, 2015 I've had no issues with coilovers mounted to the shock fixings although I do have a box section fixed across where the leafspring used to be to allow for the top links so may add some extra stiffness. sierra diff as mentioned goes in ok with a few minor mods to the body for clearance and mine required removal of the h/brake cable guides to allow it to go high enough,I use the original diff mounting points so is easy reversible,about the same weight as a triumph unit too.

James Posted May 12, 2015 Share Posted May 12, 2015 Isn't the spring likely to push the VL wonky in that setup? Link to comment Share on other sites More sharing options...
esxefi Posted May 12, 2015 Share Posted May 12, 2015 Isn't the spring likely to push the VL wonky in that setup? if you mean mine,then no as I have a 5 link a side set up,1 top arm,2 lower arms and 2 forward facing radius arms.(original one and another one above it bolted into the roll cage. all fully adjustable and very stiff.

GT6_sleeper Posted May 12, 2015 Share Posted May 12, 2015 anyone know what became of GT5r's project? It was very promising and innovative It was sold to a guy called Ian, he put a volvo 4pot in it and finished the project/paid for it to be finished. It a quick car but not my cup of tea. here is a link to some photos from the place he got some of the body work done http://www.yorkshiretriumphs.co.uk/2013/04/gt6-racer-for-track-road/ Link to comment Share on other sites More sharing options...
