Changing an engine is often necessary when the mechanics of a car are suffering and the repairs are too heavy. You can then mandate a professional to restore your vehicle to its former glory. The operation is costly but has become commonplace. On the other hand, replacing the engine in order to increase the power of your car is prohibited if it is done without prior authorization from the manufacturer.
Principle of Engine Replacement
When the engine of an automobile is sick, the mechanic in charge of the vehicle may propose an “engine change” to the owner. As in medicine, this means that he will perform a transplant. With the hood open, he will implant a new engine in the car and connect it to the rest of the mechanics.
Depending on the driver’s choice, it will be a used or standard model. New ones are almost never offered because they are too expensive; it would be more advantageous for the owner to buy a new car directly than a new engine.
Please note: the standard engine is a model that comes directly from the factory. Guaranteed for 1 or 2 years, it has been reconditioned by the manufacturer and has new and certified parts.
Why change the engine and under what circumstances?
Changing the engine block completely is not an insignificant thing and the operation has a significant cost. However, there are sometimes no other options available.
– It is expensive and difficult to repair master parts that are broken.
Turbos, cylinder head gaskets and belts are all mechanical components that are extremely expensive. A professional can, therefore, offer a cheaper replacement.
If the Engine Runs out of Steam
the heavy breakdown is close, it is essential to have the block
changed to prevent the mechanics from giving up and the resulting
problems, such as towing on the motorway.
Changing the engine is allowed when the new one is identical. If it
is a more powerful engine, it is much more delicate. In order to
drive on public roads, each vehicle has a certificate of conformity
issued by the manufacturer. If new settings contradict the
information initially recorded, you must inform the relevant
authorities of your area… with the risk of your car being taken off

examples of specific models:
