California state and US federal emissions anti-tampering laws generally prohibit any modification to the vehicle's original emission control system configuration as certified by the manufacturer. And, Section 3362.1 of the California Code of Regulations prohibits any engine change that degrades the effectiveness of a vehicle's emission control system. In this particular case the fuel injected engine is considered a more efficient engine design than its carburated counter part. You will more than likely be unable to complete this engine swap and obtain a smog inspection. For verification please contact the state smog check referee's office at (800) 622-7733.
