Is there an aftermarket turbo available for the V8 in the XC90? We live at elevation, so a turbo would be very helpful. I do know that the V6 is turboed, but we like the power of the V8 better. Being able to add a turbo to the V8 would be perfect!

 

You might be able to get a speed shop to make something for you.I think it will be a long while before you can buy a kit.
The inline 6 cylinder makes pretty good power but has a lot of lag thats why the V-8 seems better.
