well ive talked with StarBellieAngel and me and her have the same motor, 92-93 obd1 xsi b16, we both have them in 90 integra's and converted the cars to obd1. i'm not sure if you have the funds to do that swap so you might just want to stick with the obd0 b16 and yes it will fit right into your car with lil wiring just for vtec. and i love how people say the b16 in integras is slow, cuz i work b18a integras all day, were even out of the whole and then round the end of second i start puttin cars on them. and no way can you do a reliable ls/vtec for 1500 unless you did the build yourself and got hook up prices. at least thats my opinion.
