Can you put a snowmobile engine in four wheeler?

While it is possible to put snowmobile engines in ATVs, it is usually done as a custom project by enthusiasts and not something typically supported or recommended by manufacturers. Snowmobile engines are designed to operate in cold temperatures and usually have smaller displacement and less torque compared to ATV engines. Converting an ATV to run on a snowmobile engine would require significant modification and fabrication. However, it is important to carefully evaluate the technicalities, safety considerations, and legal implications before undertaking such a project.
