A turbo assembly kit (also known as a turbo mounting kit) is a set of parts you need to install or replace a turbo correctly. This kit usually contains all the essential seals and fasteners to prevent leaks and ensure proper turbo operation.

A mounting kit is crucial because old gaskets and bolts often cannot be reused: they may be deformed or damaged, which increases the risk of leaks or damage to the new turbo. Turbos operate under high pressure and temperatures, so correct and leak-free installation is essential for the service life of both the turbo and the engine.
