Give Fran a call for all those parts ( flywheel, clutch, starter) he has done the adaptation already.
As for LSD. the first digit after the 50 is denoting the differential. G97501.... is without LSD, G97502 is with LSD.
High likely it is a 1, because the new turbos are usually not equipped with LSD.
For this Guard transmission is providing a nice Auto Bias Lock up diff whci i would recommand, because it is completly open going into the turn ( thus not further supporting understear) and locks up depending on loadtransfer accelerating out of the turn.
