S55 vs. S65

The S55 will be very overbuilt. It was designed from the ground up to be turbocharged and should not be compared to the S65 which has been proven to be a weak motor relatively speaking. The E46 M3 engine was stronger than the S65 even. The N54 already supports 700+ whp without issue on the stock components and I can assure you that the internals of the S55 are stronger.
