Only a proper mechanical LSD is missing.
So I don't see any benefit in putting an 'old' N54 in a F30/32.
Don't get me wrong I had a MY2007 335i E90 6MT with the N54. Superfast car stock.
Agreed N54 has seen its last days. Lets move on and keep making the N55 better and better.

+1 I dont see why they cant make 1m or m135i variants using the N55 powerplant. Its their software they can tune and tweak it to what ever the motor will allow physically if they please.
