I've been casually looking for a sport diff (LSD) for my 328i turbo project for a while now.
I've got in contact with a bloke locally who has a written off M3 EVO.
He's suggested taking the gearbox, prop, diff and possibly even driveshafts from his breaker and transplanting the lot onto mine.
I didn't really want to just swap the diff, as it would lower the gear ratios from my current 5 speed 'box.
Has anyone done this, or does anyone know if it's a fairly straightforward job and would i need any other parts?
