Since your car is OBD2, it's likely that all they do is scan your ECU for emissions codes and check the seal of your gas cap.

JDM ECUs are NOT OBD compatible and therefore will not communicate with their scanner. Same with your OBD1 ECU. States handle lack of ECU communication in two ways:
1) Tailpipe test instead.
2) Instant fail.

It's up to you to figure this out before you go in, but I would expect an instant fail. If they're willing to tailpipe test, you'd better have a cat converter installed, which is required by law anyway.

To complete the swap legally, you need to have all the sensors and emissions items hooked up for that engine and in working order. You also need a ECU that's compatible with the that engine and of the correct OBD version. The best possible ECU would be a USDM OBD2a Integra Type R ECU. Good luck on that. Last one I saw on eBay the dude was asking like $1,200.

You might also run into issues with the engine being JDM, but again, that's up to you to check.

Ultimately you just want things to appear as stock as possible, have a cat-converter, have both O2 Sensors, have all the evap stuff hooked up, have an ECU that will talk to their scanner and have no fault codes stored.

This is general information that applies to most OBD2 testing. NJ might be different or offer alternatives or other tricks to get around it that you'll need to check,
