upgrade mp20 to an mp40?

[j5c077]

i just got an mp20 and am thinking of doing the upgrade, eventually, but if you replace the entire driver what do you do with the old one? can you buy a pump only to make use of it?

You keep the old driver and power supply. To turn this into another pump you would need a new wet side and motor.

Why not just buy a new MP40W? :D
