I think they are trying with a 330i but it would FIT on a 328, all you would need is a reflash to run it which i know is made somewhere (forgot where I saw it though).

It'll be expensive... trust me i know, but honestly 255hp isn't much over the 230 in a 328i. by adding that ecu reflash, an intake, short throw shifter kit and some headers/exhaust and you'd probably be close enough to the performance numbers of a 330i (in acceleration and speed, maybe not HP) that you couldn't tell the difference between the 2. if you want some zip to the 3 u have 2 options: buy a 335 or supercharge a 330 or 328.
I am sure that Turner would have no issue making the conversion work on a 328i. They just need to use the software from a Z4 3.0si or an X3 3.0si as a baseline. The 3.0si engines are both N52N engines just like that of the 328i.
