I think almost any BMW is a blast to drive. Owning one and it being reliable is another story. I think the M57 is the exception to the rule. N54 is gas, isn’t it?
Funny you mention BMW. Check out the BMW M57, it would he a much better swap. It’s a great engine, and is incredibly reliable and long lasting. I’d look at that way before I looked at the other one. Lots of swaps done in other vehicles and good standalone parts support.
