Bulletproof BMW Engine

[TobyB]

I'd vote late M30s, head durability notwithstanding. They got better over the years...

IMO people underestimate the M70

Would it fit in an E30?

You really don't hear much talk about the M70, eh? I just looked it up - 600+hp. Some of those old cars must have been monsters. Consider the new cars are hovering around that same mark but weigh even more. Ahh, the gool 'ol days. haha.

M30, if you forget about snapping rocker arms

if your looking for bullet proof and not performance, eta

the heads in the M30 arent what you would call bulletproof.

id say the M50NV is the best bulletproof engine, no weak points really.

a friend of mine who runs a BMW garage,, says M54B30 is the best engine EVER

I own one, so naturally I'm happy to hear that. But since the M54 is still less than 15 years old I think the jury is still out on it being considered bulletproof.

M30 is rock-solid

M20 also .. M50 is even better than these two
but a friend of mine who runs a BMW garage,, says M54B30 is the best engine EVER ,,,,

The M30 is the king for sure. That's a good rule of thumb there though.

For the I6 engines, the level of bulletproofness is more or less directly proportionate to the age of the engine's debut. M30 > M20 > M50 > M52, etc.

M30: 1968-1994. That's a heck of a span.

So Porsche has their SC engine, but what is BMWs version of a bulletproof engine? And can it go into an E30? Is it the M20? M30? S52? Discuss
