I think the principal NA-swap problem (or any swap, for that matter) is how the F22's control modules would be completely and effectively integrated with what I assume would be a different ECU/DME. If the F22's engine controller is kept, then the problem would be reversed.

I know little about this subject, but my guess is that it's a non-trivial problem. It would be great if someone here has experience in this area.

I know a fellow who, at least as of a few years ago, had a side gig at a community college in the Boston area where he taught BMW techs the ins-and-outs of this sort of thing as it related to the work they did in dealership service bays. I can track him down if anyone is actually serious about spending what's likely to be a very large sum on a swap that could easily reduce the value of their car.
