ive got a 3.91 lsd on mine and it does the job. im more interested in acceleration than top end speed though so if your after top end get a lower ratio such as 3.64 or less.i dont understand how it works but thats what ive been told

Its been done, yes they may not be the strongest engine (tend to like chewing big end bearings) but thats attainable.

Agreed, and some. If your not sure what you talking about fella then keep opinions like that to yourself. hardly helpful is it.

Guess it depends on where you want your speed in regards to the diff dude.
