Would anyone be able to give somewhat of an educated guess as to what the tuning potential of this new engine would be compared to the regular (w/ MPPK) N55? As we know from the press release it has:

-Pistons from M3/M4 S55 engine, with top ring optimized for the use of grey-cast iron liners
-Crankshaft main bearing shells from M3/M4 S55 engine
-Turbocharger integrated into the exhaust manifold
-Aerodynamically tuned air intake manifold
-High performance spark plugs (lol)

The question at hand is, is this an already tuned up N55 that is very near its performance ceiling? Or will the strengthed internal components allow for safer levels of higher boost and 400+hp with software only? Food for thought...
