where to get my diff welded?

It is. I know someone with a S13 with a welded diff and the noise it makes when he is just driving around built up areas is ridiculous, and you can hardly stop the thing going sideways in the wet.

So he has diff whine? It's broken, You can also easily stop it going sideways. All the sideways is under your right foot. :p
 
I know a guy... ;)
Did mine and its lasted a year with lots of abuse.
Im in Christchurch, Dorset. Too far?

Also makes snapping drive shafts interesting. Shouldn't be driving a car with a welded diff on the road. Either leave it as is, trailer it to deft events, or spend some money on a good LSD.

Gotta agree with this :)

Having spent far too much of my life pushing 200kg "cars" with spools (essentially the same as a welded diff, but designed from the outset to rotate both wheels at the same time making it lighter than a welded diff) I've gotta say it's no fun at low speeds, even when the car is that light.

It gets better above walking pace, but as has been said elsewhere in the thread it'll cause trouble on mini roundabouts and other tight radius turns. The faster you throw it into a tight turn, and the more you can get the inside wheel to scrub the easier you life will be, but that excuse is not exactly going to go down well with the police on the road ;)

As I mentioned we run a spool in competition, and have set up our rear suspension specifically for it (I'm not going to pretend that's my field, I just know the anti roll bar was set so stiff as to lift the inside rear wheel under cornering to help cornering at the cost of total grip)

I've always assumed the sort of person to run a welded diff on a road is the sort of person who'd bodge it up themselves to save a load of money (No offence to anyone here). Diff's are heavy beasts and you'll still be lugging all the dead weight of the diff casing and so on and so forth. To me it just stinks of someone who's cutting corners and trying to do things on the cheap.

Personally, unless you weren't using it on the road at all I'd go for an LSD. For competitive drifting I can understand why you'd want a welded diff, but if you went down that route your car would no longer be a second car, it'd be a track day special
 
I'd do it for you if you were closer. I know loads of people who run welded diffs and spools (solid pinion with no differential) on the street with no problems. Practically everyone into drag racing and drifting do it.
 
My diff was welded on my SJ, The only time you noticed it was in real tight turns you could feel the other tyre pop round.
Just jack it up drain the oil & weld it yourself.

I'm talking about the horrible clunking and banging you get as the inside wheel suddenly breaks and regains traction, putting large shock loads through the driveshafts and CV's.

You are always breaking traction on one wheel when cornering with a locked diff, irrespective of throttle. In the wet the inside wheel breaks traction so easy during cornering that overall grip is seriously reduced. Welded diffs are completely inappropriate for road use IMO.
 
All and any modifications are to be declared to your insurance company. Its in the small print. I once asked my insurer if (as I had a high lift cam in the car) I would have to tell them if I swapped it for another cam, say to try move the peak power lower, would I have to re-nofify them of the change of cam? Answer = yes. "technically" they wanted to know, even though on the paperwork it just says "performance cam". Its a change to vehicle specification and they feel the need to be told, as potentially the risk is changed.

That said my current insurer has a full list of my mods and on the paperwork they supply it actually has "etc..." after a short precis of what I'd orignally supplied to them.
 
You would definitely have to inform the insurance company, as said above, the mod in question reduces the overall road safety of the vehicle and makes it more likely to crash (compared to standard manufacturers spec) so they will def wanna hear about it

Why would you need to be defiant about it?
 
I see you're in Wiltshire? How about a trip up to Wales, Stealth Performance in Oakdale (Buffy on SXOC) will be able to do this for you no problems. Most of his work is on 200SXs and Skylines and his most recent project was an SR20DET powered MX-5 which looks like an awful lot of fun.
