Do you have access to the tech data in the workshop manual link? Yes oil turbo feed point and a crank case breather port on the rear for the collector. www.facebook.com/fiatcoupes

N/A blocks can be adapted for turbo, the breather system picks up on the sump breather port and the rocker cover to then feed to an external after market collector so all doable. www.facebook.com/fiatcoupes
