you can fit g60 mounts i believe as they are essentially just digifants with a charger, they will be more heavy duty due to the extra power they have to cope with.
you can also do a solid front engine mount which helps put the power to the wheels (pm me if you want more info on these, as i know a guy who makes them) and there are also vibratechnics mounts which are strong as well. the choice is yours!
