The diesel was detuned to keep the transmission and transfer case alive IIRC, so boosting it may not be that straightforward.
Generally the whole car doesn't have any reserves for modding, if you want to lift it or add bigger tires you're going to run into all kinds of limitations as well. Few minor issues like window regulators and rear shock mounts (can be fixed with parts from another Fiat, I think it was the coupe) and major ones like rusty rear subframes and supply is limited these days. IMHO the best thing is to take it for what it is. It's top heavy, has zero steering feel and limited grip, 70hp with healthy torque was totally adequate for that. In hindsight it was really neat but back in the day I was annoyed by how quickly everything was wearing out. Might be because I mostly have japanese cars
