A vehicle is considered to require a reconstructed vehicle inspection if the original engine is:

A vehicle requires a reconstructed vehicle inspection when the original engine is relocated or replaced with a different engine. This is due to the significant changes that can affect the vehicle's performance, safety, and emissions standards. The relocation or replacement of the engine can lead to alterations in the vehicle's structural integrity, weight distribution, and overall compatibility with other vehicle systems, which is why a thorough inspection is necessary to ensure compliance with safety and regulatory standards after such modifications.

In contrast, modifications using aftermarket parts or replacing components with original parts typically do not necessitate a full inspection unless they significantly impact safety or functionality. Keeping the engine in its original position does not trigger the need for special inspection protocols, as it maintains the manufacturer's specifications and design.
