Tell us then, why didnt they use these blocks for the N54/55 and all the rest of the fleet including the M's?
Recheck your math. 33% of 2.7 is 1.8
They could spend 10's of millions on rnd to see if it can handle boost
Or they can do zero rnd, put in cast sleeves and come in WAY under budget
Besides, if the n54 weighed as much as the n52, even the 135i/335i at stock would rival the m3
Ed: and that number 5 is bull,
Magnesium is Generally stroner than aluminium, just it catches on fire very easily lol
