How do I register a JDM import in California?

California is the most restrictive state for JDM registration. Vehicles 25+ years old can be registered as Historical Vehicles (exempt from smog). Newer compliant vehicles need a BAR referee inspection. Rotary and modified engines are scrutinized heavily. Some owners register in a smog-exempt state first (Oregon, Montana, Arizona) then transfer. California's weight fees and registration costs are also higher than most states. Consult a CA DMV specialist before importing for California use.
