N55 on one hand is more complex (has Valvetronic) and on the other hand is using cheaper components compared with N54 (use a cheaper solenoid-type injection system vs. piezo injectors in N54) to keep the cost/price down. The two Mitsubishi turbos in N54 have been replaced by a Garrett twin-scroll turbo in N55.... the rest of the hardware is the same.
