The Holy Grail of BMW Engines 

n54 and b58 is the elite choice.

If you chose the n55 its because you were simply scared of the n54😂

The E60 M5 has the best sounding engine hands down

i thought the b58 was the holy grail?

That was a weird way of saying the P60B40 4.0 L V8

S58 is king and everyone knows it.

You pretty much need to make them into s55s to make power but ok

It’s a shame no one nowadays knows about the m62tu 4.4

Only the engine makes the experience come closer to an M car? I mean, if you’re talking about the “35i” as a thing, sure, but you’re talking about the N55 as a thing. I would (I don’t have much experience about driving N20) maybe say that the N20 in the 1 and 2 series can give you a good experience because you have a good chassis, I garantee a really good experience with a B48 in the 1 and 2 series. B48 is an amazing engine…but…the N20…is nearly decent (in an Engineering opinion (my opinion). I won’t talking about “TWEAKS” and “TUNNING” and “MODS”…that’s just kinda off when talking about these things…not talking about getting 600hp in a N55 engine, I’m refering more to changing Suspension, chassis setup, aero, weight reduction. Anyone can answer and give an opinion, I would be thankful to see other opinions with other experiences, I’m not even 30 years old so I have a lot to learn!

Wut… he’s kidding right

The b58 is worlds ahead of the n55, n55 has a lot of the same problems the n20 has, open deck, bad rod bearings, old school air to air instead of the new much more efficient water to air intercooler on the new b58 and NOT a forged crankshaft on literally any of the n55 other then on the baby M variants (m235i, OG m2, maybe 135i but that wasn’t sold in America so I’m not sure) but the 335i, 435i, 535i all them do not have forged internals at all All this is fixed on the b58 minus the cast pistons which are still strong enough and a lot cheaper then full internals…and the b58 gets as good of fuel economy as the n20 so n55 is worse on gas mileage as well, fuck the n55, barely better then a n20 IMO this is why I’m not interested in one I’d rather go straight from my 428i to a 440i or m240i I’m also thinking about just cause they’re lighter
