R380 Gearbox, does it handle the torque? What bellhouse are you using? Im actually wanting to get into this swap, as i got the M57 laying from a L322, but unfortunatly it has the GM auto.
who made the adaptorplate to the engine? or did you meassured the bellhousing on the rover and likewise on the bmw and made the drawing and machining yourself? I have an M21D24 which is going into my LR disco1 so all info is of interest :) cheers
