How many kms should a turbo last?

I'm curious to know, in the realm of automotive performance and turbocharging, just how many kilometers should a turbocharger be expected to last? With the constant demands placed on these precision-engineered components, it's essential to understand their lifespan. Aftermarket parts, factory installations, and various driving styles can all play a role in the turbo's durability. Is there a general consensus among experts on the average lifespan of a turbocharger, or does it vary widely depending on the specific application? I'm interested in hearing your thoughts on this matter, as I'm considering upgrading my vehicle's turbo system.
