The emission is a standard number no matter what motor you have. Have it be a LS or a GSR.

You need to take your vehicle into your State Bureau of Automobile Repair (BAR), have it inspected, if everything is done to meet your local/state regulations they will give you a sticker that verifies your engine swap has been approved by the state, and you will be able to smog and register your vehicle. Things to consider, year of vehicle and year of motor. Generally the state requires that the motor be at least as new as the vehicles year of production or newer. Second, it will be much easier and headache free if your vehicles OBD is the same as Your motor swap. 95 and older is OBD1, 96 and newer is OBD2 (im only considering the extent of the integras production year). Mismatching OBD legally requires extensive modification to the fuel system, there are a number of sensors OBD2 vehicles come equipped with and if your OBD2 ecu isnt getting readings from those sensors you will constantly throw a check engine light which would make it impossible for you to pass smog. Im giving you examples based on californias emission laws, i do not know where you live or what your state laws are. Assuming You meet the previous guidelines, what you will need to pass BAR inspection are: the correct, unmodified ecu for the coinciding motor, in your case it would be a P72 ecu. Make sure all vacuum lines and hoses are connected correctcly to pass underhood visual inspection. Your catalytic converter has to be functioning properly and be able to pass a "sniff" test. And EVERY part on your car must be CARB legal. Your best bet is go to the ref station with all stock intake components, and exhuast components that includes exhuast manifold(header). If you do all that you should have no problem passing inspection. I know it sounds like a lot but its really not all that much. Good luck dude.
