The term «swap» can have different meanings depending on the context used. It is most often associated with cars, but is sometimes used in other fields as well.

In the automotive industry, engine swap involves a complete change in the power unit (internal combustion engine, internal combustion engine) with the possible replacement of all attachments or parts thereof. Most often, swap refers to the installation of a more powerful engine, which allows you to increase the dynamic characteristics of the car. However, this term can also mean replacing the gearbox or adding all-wheel drive to the car.

The main reasons why car owners resort to swap may include: the breakdown of an old engine when its restoration becomes impractical or too costly, as well as the need for an engine with more power and torque to improve the performance of the car on the road or highway.
