Now define reliable. For 99% of people, a reliable engine is how so little you go to the dealer. So the N54 is not reliable.
However, for an enthusiast 'reliable' means is the engine will explode under load. Now the N54 is very reliable.
It's relative.
Even direct injection was fairly new, and imo this is what kill the decision maker. No aftermarket, new and even used injector cost more than the engine itself.
Other items is secondary imo, once it's done, you're good to go.
Do a single turbo, and already you remove a lot of unreliable items !
B58 got a lot of glory, but it's way more expensive right now. Btw b58 as almost all n54 issues, simply it's now coming since the engine starting to be old, and the item of concerns are expensive to deal with.

That’s the real take right there.
700whp on stock internals for an engine designed in 2004-2005 is wild. That’s why people forgive it. Cheap car + cheap power + strong bottom end = instant legend status.
You’re spot on about “reliable” being relative.
Dealer-reliable? Nah, the N54 isn’t.
Enthusiast-reliable? Yeah, once you fix the known stuff it’ll take abuse all day. Most of the pain is front-loaded: injectors, HPFP, water pump, walnut blasting. After that it’s solid.
And the DI point is key. In 2006 there was no aftermarket, no cheap injectors, no real data. That’s what made it painful early on. Single turbo fixes a lot of that too - kills wastegate rattle and simplifies the setup.
B58 is getting the same treatment now. It’s cheap enough to mod, old enough to have issues, and people are realizing it’s not magic either. Just cheaper to deal with right now.
So no, not overrated. It just gets judged by modern standards when it was built 20 years ago.
