Can I swap out my motor and replace it with one for California emissions?

What is your question?

I have a 2010 Nissan Altima 2.5L federal emissions without Hybrid. I need to replace my engine and within close proximity to where I live I have found numerous motors at a relatively decent price but they're all most California emissions. Since I don't have to pass a smog test and I don't really have a concern for California emissions what I need to know is: can I swap out my current motor for one that came from a California emissions Altima?

How long has your 2010 Nissan Altima had this problem?
