What alternator for my swap

Ok here is the breakdown, have a 95 ls teg with a b16 swap(yes i know,,why b16, it was like that when i bought it, ignorance yes). Now one of my buddies told me I have a SOHC alternator which is not good and it makes sense because If I let the car sit for more then a couple of days my car needs a jump. If I get a new battery a couple months later its the same thing.

So my question is what alternator do I get for my car? Do I get an alternator meant for the gsr or the civic si or are they the same?

Thanks for the help in advanced

why dont you take the B16 head and put it on the LS block...that would be a good combo because the B16 in the Teg is not going to be fun....my buddy James did that and it was pretty lame....then we built an LS/VTEC...problem solved

Umm that doesn't really answer my question, I am looking for what alternator to put in my teg, will any alternator from a DOHC work?
