Does anyone know if there is a place that sells a turbocharger kit for a 3.1 and if not is it possible to custom fit a turbo?

 

there are no turbo kits for the 3.1. if you have the fabrication skills (or the money to pay someone to do the fab work for you) you can put a turbo anywhere you want. most guys i've seen mount the turbo between the radiator and the serpentine belt.
