As far as we know there are no 'bolt on' turbo kits for this vehicle.
This will need to be a complete custom setup, in order for you to be able to install any turbo on your vehicle.
It will need custom intercooler setup, with piping and all other hardware. Will also need custom manifold for the turbo and proper tune.
Putting turbo in a Xterra is not very common but there are few that have been done.
I would suggest doing some research to see if this were something you would like to tackle.
Also, if this is your daily driver, it might be a good idea to have a second vehicle as this type of setup can come with unexpected issues.
Let me know of any questions.
