Will this diff go into my S5 turbo?

 

If you have a TII rear end, which it appears you do, it should.

 

Yes, it works.
You need to be able to adjust the ring to pinion contact patch.
If you have no idea what that is, take it to a drivetrain shop that can do this for you.

will it fit in a s4 turbo? what kind of lsd is it? 4.xx

 

It'll fit either turbo.
It's a Torsen.
LSD's don't have ratios.

so is there any custom mods involved or will it basically bolt right in?

 

It bolts right in.
Don't be fooled though - with any LSD install, the ring and pinion has to be set correctly, and this isn't a job for a newbie.
If you don't set it right, you're going to end up destroying the entire differential.
