Struggling to find the correct clutch for the GS6-53DZ gearbox out of a 2010 330D. Just bought a used one from ebay only to find that the spline diameter was wrong - the gearbox seems to be 35mm, the clutch was 30mm.
The disclaimer here is that I've no no experience of BMW myself and this gearbox isn't actually even going in a 330 - the project I'm working on is a transplant of this engine mated to a 450WHP/800NM Merc OM606 Turbodiesel, going into a 1986 G wagon to race in the Tuareg next year. Mercedes don't make a manual box that will hold much north of 600NM and whereas the 5 and 6 speed ZF boxes from the 3 series diesels are good for 1000
Appreciate any help.
