yes the b16 is a bolt in for the EG chassis, it all depends on the year of the motor and what drivers side engine bracket that is on there, mine was an OBD1 model but had a weird bracket on there, so i just inbolted the one form my single cam and used the GSR big mount for the drivers side, which is what most people do.

as far as shift linkages go, yo need an integra linkage, the del sol will not work it is unique to only the del sol, and you cannot use the one from you crx, i know it suck but thats how it goes.

as far as axles, i used 99 integra gsr non ABS in mine and they work just fine, no issues at all. the intermediate shaft that is on your motor is fine to work with other axles as well
