OapEM has got his Dusty Drifter set up lowered and welded.
And it runs fine as a daily.
Read the thread man, might be of some help:

cheers mate

hopefully i pick mine up tomorrow, when i used to work at mercedes an old guy who worked there used to have one, brought from new i think (g reg) and never really thought anything of it, read about it in the back of a autocar mag, thought they sounded more fun than they look,

there is a 2nd hand car sales place next to where i work at the mo, and last week i noticed the old mans car appear, found out he had traded it in, so looked over it it, seems pretty mint, no rust anywhere, only oil leak seems to be from the gearbox/diff, but doesnt whine or anything. its got all the documentation from services mot's etc etc. and has done 98k and is a 1.7, the old guy who had it drove it gingerly, so its never been ragged either ]. (he'd moan at me if i accelarated quickly if he was in the same car. lol.)


my current car, a starlet gt turbo, is currently up for sale, so i was looking for a car just to get about in, and they only wanted £300 for it so i thought i'd have it. lol.

and as i have looked about the net, have slowly fallen in love with them, especially when they are decked on some deep dish alloys. lol

yeah man. You cant do better in rwd for the money.
And they are a bit elderly out of the box.
But with a bit of dish, hit with the lowering stick and some uprated springs you end up with a lot of fun for less than the price of a set of nice JDM Rimz Yo!!11

Had a welded diff on my old Sierra, now got a welded diff on my Volvo 360. Both of these cars were/are used as dailys (i'm not rich enough to run two cars at the same time, so my fun car is my daily too :lol: )

Welded diffs are IMO fine for regular road use, the skipping and understeer isnt as bad as uneducated people make out. The only minor ball ache is you'll get though tyres quickly, but TBH if your going to get sideways tyres are the last thing you should worry about! Do it you'll love it 340pw

i have a volvo 340 1.7 lowered and welded diff and use it as my daily driver and its fine eh you dont notice it til you try u turns and your 3 point turns will go out the window till you get used to it and if you try and floor it round tightish corner it will just understeer to death but you relly have to be going for for that to happen
you dont have to be overly careful just dont drive like a fud and you will be fine lol but i have to say the welded diff is the best mod
ive done yet makes it way more fun when skidding in the wet and it is piossible in the dry and my car isnt even stripped out. not easy like but it can be done with enough commitment (and clutch kicks lol)
anyways goodluck to you whatever you decide to do
cheers

I've had my car on the road with the diff welded for about a month and it's no real problem, if it brakes down you just can't push it round corners :lol: it's fun though and good when the chav kids in fiesta STs are laughing at your old car, you can just slide of round the corner!

I welded my diff as well.

I ain't got any problems with it (only extreme oversteering ;)) It handles about 160 bhp and it holds it for a year and a half.

Let an experienced welder do it. Make sure you welded it hot enough and let it cool down slow (no cooling with water!)

You can get LSDs and locking diffs on some 940s, but nothing that will fit a 340/360 without huge modifications. I once considered a chain driven affair that would bolt into the the CV joint bolts and lead to some viscous coupling device, but it has to take potentially the full force of the drive so it needs to be in oil and use solid gears.

BMW do a nice braking system that slows a spinning wheel thereby transferring the torque to the grippy wheel, but it only seems to work at slow speeds. Would require a bit of development and electronics. Electric drive using 2 motors on diff end of the CV joints might be interesting, but then it would probably be better to take out the mechanical drive altogether, thats next years project.

They were available a while back. I've a volvo based motorsport catalogue from '97 that lists them. I've rung the company up just to check since I've got the brochure and they couldn't get them anymore.

If you can buy a nice cheap direct fit LSD then thats cool, but if it's major work why bother? Either keep it with an open diff and except that you'll find it difficult to put power down or weld the bu**er up and put up with the fact it'll hop and skip a bit at slow speed (which you'll get with a tight plated/mechanical diff anyway).

Viscous LSD's are they are a bit pants, they arnt that predictable and don't always lock! A friend of mines recently done a 24v conversion into his E30, and paid over the odds for a OE viscous in a crap ratio which he then spend a fankly silly amount of money getting it reburbished, and then it still only leaves one black line when he nails it :roll:

Rant over :lol:

Depends, if you want to drift it great, but with the driving I'd do I'd likely continue to get nowhere, or spin it off in a hedge. I drive where the conditions are nearly always loose, slippy, or a mixture of both. Open I struggle to pull away, let alone quickly, and welded... well, I need something that I can hurry along without the side effects. For some reason over the last x-ty years rally teams havn't been fitting welded diffs to their cars.
