I think 3 engines ( N54, N55, B58 ) are same level.
N55 has the worst oem manifold and that makes look as the worst of three engines.

N55 oem manifold is only pushing with 4.5 cyl the turbine side

N55 is certainly the last among the 3 regarding performance potential. B58 is probably the first, but time will tell. That open deck on the N55 isn't helping it last once you start getting over 600whp, then cast pistons & rods.

It will also be cool to see what point the B58 intake manifold/IC becomes a restriction because that isn't easy or cheap to replace. It could really limit the platform to most people.
