Hello all, I just recently (yesterday) bought myself an 06 Legacy 2.5i Special Edition with the harder to find than I thought 5-speed manual.

 

One question my friends and I had while driving it home was.. can I swap the diff in the rear with a limited slip version from the turbo model, or a wrx?

 

Thanks

Yes, you can.

 

I don't have experience with this but I've heard others say that the rear viscous units can have a limited life span and "wear out" turning into little more than an open diff. If that's true a low mileage unit might be preferable. I dont' want to pay top dollar for little or no gain.
