Subaru Evo spec 5 Lsd

[Auturbo6]

Hey everyone,

My brother in all his wisdom, has today purchased a 2002 Subaru impressa Evo spec 5. We've had many discussions about what car he should purchase in recent times, i say evo 5-6 he says he wants a wagon, i say put a tarp between the roof and the coffee table on the back, he tells me where to go.
Any way, to the point:

Would anyone out there know, if the Evo spec 5 has a rear LSD fitted: and if not who would one see for such a component.

Have never liked subaru's so have never acumulated any knowledge related to them. Have always been a mitsubishi man.

Please no jack the back up and spin the wheel, he hasn't yet taken delivery of thy said vehicle. Any and all help is greatly appreciated.
