direct injection allows for higher compression ratios - its not THAT much lower. s54 was 11.5 to 1 n55 is 10.2 to 1. its not 8 to 1 or 9 to 1 like you would see in turbo subarus.
also - s54 longevity was never an issue. people beat the CRAP out of it (the turbo ones) and rarely had a problem.
all im saying is BMW made the S54 in 1999/2000. and HPF hacked together a turbo in mid 2000s. BMW couldn't pull off a better engine?
don't get me wrong the S54 is going to be cool. but it just leaves you wondering what they could have done if they werent trying to make a good car/engine and weren't just looking for ways to cut costs and ///Marketing
by ///Marketing i mean that they couldn't have the M3 out-perform the M5.
