I think it was the air intake setup and injectors that we're different as well as the turbo, I can't remember the exact details now but I still miss my 211 with that engine.I do wonder what the real differences are with those engines.
The 612 has 370 N⋅m @1600–2800 rpm + 125kw @4200rpm.
The 647 has 400 NM @1800-2600rpm + 130Kw @4200rpm.
Apart from Variable Geo turbo's they seems to be identical...
