Yes, I believe that's correct. Both motors are "built". The TW guys told me that N55's starting from the 435i and 235i are made from better parts. ie not cheap cast pistons like used in past N55's. But still... you can't really go beyond the 410 PS level without getting into the engine. Their 730 PS 1M monster has 30K of track use without any internal engine work. That's quite something I think.
