What is Engine Swap?

A like-for-like replacement is simpler than a different engine type. Electronics, mounts and cooling often need changes. Many countries require approval and registration of the change. A swap can change the car’s emission class and tax category.

How it works

The new engine must be integrated mechanically and electronically with the car’s systems.

Why it matters for your car

Unregistered engine changes can void insurance and fail inspection. Brakes and suspension may need upgrading for extra power.
