Summed up nicely by M3 Adjuster :D

Turns out that this engine almost feels like a detuned S55 than a tuned N55 (that sounds better ;) )


Thoughts?

Closed DECK It refers to the space between the cylinders on the deck surface (where the head mounts). Closed deck means the space around the cylinder is solid. This equals strength. Open deck means the space is open. This offers better cooling and lighter weight at the expense of strength. open deck engines tend to be just fine for natural aspiration, its forced induction that can get the better of the design. , the open deck design offers better cooling and this is because a)there is waterpockets very close to the combustion chamber and bore and b)the bore and cc are cooled more uniformly. high revving engines produce much more heat and this design suites them well as long as they're naturally aspirated. for extreme outputs and forced induction a closed/semi closed deck is much more reliable and durable. Forged Crankshaft Since there are probably books dedicated to this.. suffice it to say that When it comes to metals... Forged metal is stronger than Cast metal. Along with the other items reworked Turbocharger integrated into the exhaust manifold Aerodynamically tuned air intake manifold Separate oil cooler Pistons with a modified top ring It appears that the internals of this motor have been reworked for much higher durability... which of course is needed whenever you are elevating boost levels....which is of course the easiest way to make power in a turbo motor application. Well.. that and changing out turbos.. Which is probably the final piece of the puzzle that has not been released.
