when i swapped a 97 b16a2 into my 94 del sol doch vtec, i kept the same wiring and obd1 setup. i just sold it last month, the only way i got it to smog was because i knew someone who knew someone, so that way I did not have to get it reffed.
Basically in a nutshell, it is going to be a fairly complex process. 1, you will have to go from OBD1 to OBD2, and from D series to B series. You do not have to swap youre radiator but it would help to take the radiator during swap, no real need to switch radiators. my dohc vtec del sol radiator would always get super hot and my aem intake would get hot as hell, they dont eeally help it cool any better than the stock wide version.
You can either go smog your car and re register it right now with the stock motor, then swap. or you could do it all the right way by swapping and updating to OBD2 and getting it to pass 'ref' aka state referee's association and then smog and that way if you get pulled over and harassed by the cops you wont lose youre car. because the cops will either A. make you drive youre car straight home and not drive it again until your appointment with the ref's, if you get caught driving it before then you lose it for good.
or B. they will impound it and screw you over royally for thousands. and you still might not get youre car back
i may be only 19 but ive been harassed by my fair share of oink oinks here in san diego.
