Welded V-LSD... can it be done?
 

I need to do something about my crappy slosh-bucket Vlsd.
Trying to get to a few clubloose events this year, hence I need something that ACTUALLY locks. A 2way would be great, but funds are limited as always.

I've read that some 240 guys do this and that some shimming is also involved, But can a Turbo rx7 V-lsd be welded? Do they not have spider gears? please forgive my ignorance of viscous differentials. Any information/experience would be appreciated.

Found this on driftworks...
http://www.driftworks.com/forum/tech...sd-advice.html
Seems like they never posted the final outcome/results though :/

comments, ideas? anybody?

Is the car strictly for track?

^yupp, just drift events... and summertime cruising every now and then.
I already know the bullshit that goes along with it: screechy tight turns, bald tires, no wet traction, bla-blah. Been through that thread already.
And it seems that no-one really cares about viscous diffs anymore anyway, wouldnt get much money if i were to sell it

from what I understand, the gears can still be welded together. They're just a bit harder to get to since the unit is pretty well enclosed

not many guys here are into these mods.
try the drift section.

From that link, id assume the diff is similar, could work. should be pictures in the fsm to see what it looks like. I hate welded imo, kept breaking them in my car. If you could get your hands on a s4 lsd, you would be set.

An s4 clutch type would be nice, but by the time I buy the diff/pumpkin/stub shafts/drive shafts that need to be switched over for it, I could be well on my way to a decent 2way.
I know its the cheap way out, but i'm just starting out this year. It will give me something to work with while I collect the funds for a real diff.

I'll check out the fsm. good idea.

yeah s4 clutch lsd, people tend to sell them at a premium when they know what they are lol

So im taking it that you cant replace the fluid inside the viscous? if i recall its thin then when its understrain it becomes thick? or is your viscous just blown?

The fluid can be changed, I changed mine a few months ago to see if it would improve the engagement.

The problem is that the unit relies on temp differences in the fluid (or something like that) to make it lock up.
So it gets too hot, and it stops locking and is basically as useful as an open diff. I noticed it at autocross, so theres no way it will hold up for drifting.
