BMW probably realized a large OEM d0wnp1pe was a good way to increase power/efficiency/mpg with little sacrifice.

N55/B58 have to the be the first engines in the last 30 years that doesn't make more power from a dawnpipe lol

The main thing is a PS2 turbo... We also have port injection and run E50. You could probably produce a similar result on WMI though.

BMS intake, and some intercooler. I don't remember what we have on it but anything aftermarket would be fine.
