915 some help please !!!

[Jim Hunter]

Hello,

I would like to install a 8:31 alloy 915 with lsd in my 1303.
I am using a 2.1l wbx engine already with its stock efi.
I am running 15" inch mahle gas burner wheels with 165 R 15 tyres.
It is okay to put it or should I check to find a 7:31 ???
What about the pressure plate/flywheel,cluth and t/o bearing setup ?
Anyone has done this to help ?

Thanks!
