stock skyline diff's start at £400, getting a good one is the issuethe long nose/Quaife route is sort of capped and straight forward at about £1000, whereas the short nose route has diff, mount/cradle and driveshafts to source and to put together. might not be much cheaper than £1000?
It depends on the gearbox, you can get GTR ratio that's 3.54 out of a 6speed car
I'm suggesting he looks at the options.
So you have an LS-powered car then?
This would be better than a long nosed stock diff in Datsun 280Z which are dumped when used by the said drift cars
So you're not necessarily recommending a 'GTT' diff now?
I'm not sure I understand this. The OP has a UK market 260Z 2+2. What has a 'Datsun 280Z' got to with it, and who is 'dumping' the diffs out of them?
I know you like the merry go round of answering in detail until people give up so you have the last word.
The R200 long nose comes in 280Z...
...these are used for several drift cars and the diff's are dumped for not being strong enough
the other stuff is based on what gearbox/ratios are they using, I doubt he would use the stock gearbox?
expecting another long response from you
you can change ratios in GTT, they are not that expensive
depends on his gearbox?So, he can buy a short-nose R200 from a 'GTT' (with a 4.08 or 4.11 ratio) for "£400 on ebay", and then change the ratio to something that came as stock equipment in another variant of short-nose R200...?
I think I'm getting the hang of this now.
So how are all these Zs driving around with RB25 and LS without issue. I don’t want to fall foul of the law but I want it to be strong enough to take 600hp. Any advice would be helpful thanksJust as a point to consider, if you're changing all the engine, suspension, drivetrain etc. You won't be able to change the gearbox or steering without falling foul of this: https://www.gov.uk/vehicle-registration/radically-altered-vehicles
you will be needing a R33 or R34 GTT diff then.... with 600BHP take your pick on your ratio as it depends on the gear ratios in the transmission but 4.1 should be close. You are in the Hybrid Z section really, you get less attention from Albrecht in thereSo how are all these Zs driving around with RB25 and LS without issue. I don’t want to fall foul of the law but I want it to be strong enough to take 600hp. Any advice would be helpful thanks

Stock UK market manual transmission GRS30 was equipped with a 3.7:1 R200
You're welcome to have the last word, but you need to be right.
A 3.545 long-nose R200 might actually be a pretty good package component for an LS-engined 260Z 2+2 street car, ironically enough.
Maybe he already has a 3.54 in his car……
....and this, being from a two seater, is liable to be a 3.7 : https://www.ebay.co.uk/itm/Datsun-260z-rear-diff/332957851539?hash=item4d85d59f93:g:ZxwAAOSw-VtbJkSi&LH_ItemCondition=3000 if he prefers that !

Is this the LSD you mentioned? https://shop.quaife.co.uk/nissan-200sx-s13-quaife-atb-helical-lsd-differentialI think the final drive ratio will (should) be a key point in the selection, and the quoted 'GTT' diffs seem to be going in the wrong direction ratio-wise in my opinion.
A 3.54:1 ratio long-nose 200 (stock equipment on Automatic UK RS30/GRS30 models) with a Quaife helical LSD conversion will be a bolt-in (less faff than short-nose) and could accept the ZCG CV axles @TheHulkGB has cited in his first post.

R200 long nose is more than strong enough and won’t ever really be the weak link in the driveline. I’ve got one in my LS swapped 240Z, 3.54 ratio - good choice of helical / plate diffs etc.
I would avoid the short nose as with that kit from T3 the front mount for the short nose diffs in poorly designed as it gives quite a lot of leverage force and many have found that its not solid enough with big power, enough that many have had to change from it.
Long nose R200 is plenty strong, I run near enough 500hp and 490lbft through mine with no issues and many are still running one with up to 800hp.
