Looks amazing. I must say though I'm pretty disappointed they didn't stick with the "oversquare" design that was initially published. Kind of gave the s55 it's own identity over the n55. Not to mention you don't really want an undersquare block when revving high..
Maybe they wanted to produce more torque down low and focus the powerband of the turbos up top?
Anyways I'm sure the head and cams are probably different to make power all the way to 7600rpm.
