If you're willing to do the swap, I think it would be at least the same performance for probably a few bucks less. I mean, the DA Supercharger kit is $3,395.00 for the E36 kit, and the E30 kit is even more (due to having to replace the crank pulley with a hybrid vbelt/serpentine pully).
I'm not saying it's a bad way to go if you already have a 91 318is, but you're A: Going to pay more for a 91 318is (they're pretty sought after) and B: going to spend more on the supercharger than an M50 costs. A 1500 dollar E30 + a 2000 dollar M50 will get you the same peformance, better reliability (IMHO) and probably better fuel economy (although that's a SWAG). The 318is Supercharged, on the other hand, will indeed be lighter.
Just my $.02.
