MK3 JDM emmisions/fuel

I want to replace my blown stock 7mgte with a JDM 7mgte in my 91T. I want to know if the emissions equipment from my stock engine can be swapped onto the JDM engine to make it emssions legal in CA. I also want to know if the JDM will run good on 92 octane american fuel. If not, will an octane booster help? Any responses will be greatly apreciated.
