In addition, manufacturers have different ideas of what it means durable.
The engine must retrieve his power anytime, anywhere permanently. Whether it's at sea level at -60 C in Sweden, or at +60 C at 3,000 meters above the Death Valley.

And I can guarantee that a N54 creates even with modifications under these conditions, no 450 hp without going broke!
Not sure what you are talking about.

~400-420 BHP is what you get with a JB4 and no other mods.

ETA: and the only "durability" problems have been related to BMW design flaws, not increased power.
you are a winner
