BMW N54 vs N55: Which One is Better?

Article: https://dustrunnersauto.com/bmw-n54-v...

Both engines are very similar in many aspects and stock-for-stock perform nearly identical. The N54 offers peak torque 100rpm sooner and slightly better throttle response, but it’s barely even noticeable in real world driving conditions. Both offer pretty poor reliability, with the N55 being slightly better. Thanks to the N54’s twin turbos and forged internals, it is the more capable engine mod-for-mod.

Realistically, they’re so similar in terms of performance, that you can’t exactly say one is better than the other. The N54’s forged internals are marginally stronger and the twin-turbo setup allows for a bit more power on the stock turbo setup, but the N55’s improved reliability makes up for any gaps in performance. We think the N54 is marginally better, but not but much.
