ok, i didn't read this whole thread (it's too damn long with too many off topic posts), so don't flame me if this has been said before in this thread. a b16 is a great swap for a crx or 4g civic as has been said many times, it is actually the only cars that i like the swap in. one reason is weight.. a crx weighs what? like 2,000 lbs., i think that 111 lb/ft of torque coupled with a 8.2k redline will pull it along quite well... strap another 500 or so lbs. on that it the results may not be so great. the other reason i like that swap is because of the obd compliance. it's the only vtec swap avaliable from that obd, therefore it cuts down on wiring, dificulty and price. i would take a stock b16a SiR over a stock b18a anyday. the slight torque advantage is not enough to compensate for the lack of high revs in my oponion. only thing that puts the ls above the b16 is when you boost 'em, which a totally different argument. my vote: b16a SiR.
