The engine would slide right in the middle between the 335i and the M-car..
The M135i F20/21 has a souped up N55 and is almost as fast as a 1M.And we're talking M Performance, not even //M.
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.
