After chatting with my local service station (also licensed for inspections) They suggested actually going to a state facility first to get a baseline for your emissions. The emission standards are based on the model year, and they are different than new cars, but my shop didn't have the exect specs. By having a newer engine (and hopefully cleaner than the original) it should be OK. I'm not a fan of NJ state facilities with their lack of concern for your vehicle, but it's a decent idea. (So much for my thought of going to a private facility first!)
