In the mustang community, a single walbro 255 is enough to support a F/I'd 500rwhp. Unless the rails in the bimmer are rediculuously tiny (higher pressure), I'm not sure why it wouldn't be the same. Another thing used for forced induction applications is a boost a pump. In essence, it a voltage regulator for the fuel pump....boosting voltage only when necessary. I'm not sure how this would tie in witht he bimmers electronics, but it's worth looking into as they aren't terribly expensive.

Here is the boost a pump...

I'd recommend scouring for more information. While it used to be turbomustangs, there are quite a few non mustang projects to be found, as they are now more of a universal turbo DIY website.
