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.

All very good points. Just like Porsche holding the cayman back..wouldn't want to tread on big brother turf.
