N54
A BMW turbo engine known for both it's horsepower potential as well as it's power to make it's 4th owner go broke with maintenance cost.
The turbo started rattling soon after I replaced the 3000$ injectors on my n54.

Steer away unless you enjoy buying the same engine parts every 3 months
The n54 is the new 2-JZ only if chickens learn how to fly!
