could i use this ram in a fp system (giving me 1000kg of power)with a leverage of 3 or 4 to 1? would the ports be big enough?

The cylinder you linked to has a Port Size #4 SAE = 0.172 min dia

All the above is just a rough guide .... real world has many other variables.

EG ..Can you open the supply valve fully in less time than the math value for the ram extension time?
