Can all who know for certain, let me know the similarities and differnces between the two engines please, no need to state the blindingly obvious re turbos and manifolds, after internal differences more so please. Particularly:
Sump
Oil Pump
Block
Crank and rods
Heads
Pistons: Yes I realise the compression differences, but more as to their constuction and tolerances to being worked?, And any other handy bits of info between the two?
Ta!
