Im no pro but an lsd usually helps with launches. Unless your doing neutral to drive drops and ******* your tranny you really dont need one, Your not launching that hard. But to answer your original question YES it is possible but it would be all around easier to swap the entire rear end.

lsd also helps every time you turn the steering wheel. so it makes sense to want one even in an auto.

Yeh, it's possable, as long as you grab an N/A LSD carrier, or swap the whole N/A diff out. Otherwise you need a custom driveshaft to let you go with a turbo LSD.

Seriously? OOooo...need to find one of those. I'm going to need an LSD. This is why Icemark rules, so full of useful information.

I thought the drive shaft from the autos tranny was different though?

The shaft is different on the tranny side, not the diff side, from what I can see.
You can swap out any N/A diff, you dont just need to get an auto GXL diff. I cant see a difference.

Rotary legend contents some of these LSDs had 3.90 ratios. Any validity?
