Just say'n
E30 - yes, but S14 achilles heel is torque...specifically lack thereof.
E36 - no, heavy for it's poswer potential due to limited compression and camshaft lift rules.
E46 - can make Huge power, but has to weigh 3500+ pounds - on an 8" rim, with a tiny wing.

It may take a year of E36M3's running in STU for it to happen, but eventually I think they can be made compeitive. right now, doubt it. E46 325/M54 engine is a better choice, more power and less weight than an E36 M3 S50/52.
