Would it be worth it?
Much cheaper to slot in an S65 engine and DSG unit.

Weight. The E90 335i is 220 lbs heavier than the 328i sporting the NA version of the engine. With a similar saving from the F80 we are at 3300 lbs with no other lightening of the car.
The E92 M3 GTS is 300 lbs lighter than a E92 M3. Give this hypothetical NA F80 limited edition the same savings and we are at 3000 lbs ( with driver which close to an E30... ). Then increase bore as far as cylinder walls safely allows it and you will have quite a machine that will have little problems smoking a 335i and the sound of an NA I6 at 9000 rpm will be worth it alone.
