Can a Naturally Aspirated Engine Modified to Turbo Pass the Annual Inspection?
1 Answers
Modifying a naturally aspirirated engine to turbo will not pass the annual inspection as it constitutes illegal modification. Relevant legal provisions: No unit or individual may assemble a motor vehicle or alter the registered structure, construction, or characteristics of a motor vehicle without authorization. Without permission from the public security traffic management department, any unauthorized modification to the motor vehicle's chassis, engine, suspension, transmission system, steering system, tire rims, lights, body color painting and exterior structure, as well as any technical data of the motor vehicle that does not match the data announced by the competent department of motor vehicle products under the State Council, are considered modification acts. Precautions for modification: For the powertrain, only the original factory engine can be replaced, and an application for change registration must be submitted to the vehicle management office within 10 days after the replacement; the spraying or pasting of logos or body advertisements on motor vehicles must not affect safe driving; the body cannot have more than three main colors, and the use of fire engine-specific red, engineering vehicle-specific orange, police vehicle-specific blue and white, or special vehicle-specific camouflage colors is prohibited.
