you may want to do a search on this....it seems that your understanding of how angel eyes/projectors, and hids is fairly rudimentary...
but here are the basics...
if you want projectors, you can either use one OR two in each houseing, but because the gen3s use two different bumbs for highbeam/drl and low beam, if you want your drl and your low beam to both have projectors, then you need two- or some people only retrofit it for the low beam
remember:
-if you're planning on using hids without projectors, you'll glare like mad
-if you're planning on using projectors w/o hids and without clearing your lenses, your beam pattern will get broken up by the lextured lense
- if you're planning on using hids with your projectors, you don't need to clear your lenses
and IF you really want angel eyes with your projectors, then it would be easiest to buy a set of civic halo+projectors off of ebay, cut it out of their housing and then retrofit it into yours
but personally, I don't think angel eyes fit on any car by bimmers
have fun
