I don't know if you understand the other posts written in Italian, but the situation is that you can put the GPunto Abarth turbocharger without any other hardware modification. If you want to use a larger turbo, you have to modify the exhaust manifolds and (depending on the fuel map, so depending on the power output you want) higher capacity fuel injectors.
Be aware of the fact that in case of very high torque values the gearbox could have major problems, because it is different from the one installed on the Grande Punto Abarth stock/ss.
Hope now the situation is clear...
