This one is really interesting... I'm trying to find out if the 20i can be chipped to the same power levels as the 28i so that I can replace my wife's E90 328 with a F30 320 instead of 328
Some on the 3er forums suggest that the heads and turbo are different across the various N20 equipped cars and other details such as smaller brakes make it more worthwhile to get the 28i in the first place as opposed to try to bring the 20i up to that level
Did you come across more details ?
