probably a 255 intake would be fine, don't know if they come any bigger and then when you get the kit you will add an extra in-line pump, whatever they give you.
if you are unsure and want to use whatever comes with the kit then just get a smaller pump for now but then you will be dropping the tank twice, have fun with that
