How expensive is it to install a turbo?

I'm curious about the cost involved in installing a turbocharger on a vehicle. Could you please elaborate on the various factors that can affect the price? I've heard it can range widely, so I'm interested in understanding the main drivers behind the cost. Does the type of vehicle make a significant difference? Are there any specific parts or components that tend to be more expensive? And does the labor cost vary depending on the complexity of the installation? I'd appreciate any insights you could provide to help me budget for this potential modification.
