you have to cut it some slack, it was a fairly new platform issues are to be expected, the only reason the b58 is reliable is because bmw has been perfecting the formula for more than a decade. The reason it’s so loved is for most people it will probably be their first proper fast car, as well as most of the n54 cars being mounted on a almost perfectly balanced chassis that is the E9x. Cheap power with good handling how can you hate it? take care of it and it will take care of you

Straight up - you’re not wrong.
The N54 was BMW’s first swing at a modern turbo 6, and yeah, first-gen stuff is always gonna have teething issues. The B58 is reliable because BMW spent a decade fixing everything the N54 broke.
And you hit the real reason it’s still loved: E9x chassis + cheap power. 50/50 weight, RWD, hydraulic steering, and you can make 450whp on stock turbos for under $2k. That combo is addictive, especially if it’s your first “fast” car. Once you feel that, the injectors and water pumps feel like the price of admission.
I’ll only add this: “take care of it and it’ll take care of you” is true, but the maintenance schedule is more preventative than normal. You’re replacing stuff _before_ it fails, not after. Most N54 owners are cool with that because the car feels special when it’s running right.
If BMW dropped the N54 today with the same reliability rep, it’d get roasted. But in 2007 on the E9x? It earned the hype.
What’s your setup at right now - stock, FBO, or bigger turbos?
