Yeah, you need to calculate the volume to figure which orbital you need, to do that you need the bore. to calculate volume its pieX dia2/ 4 X stroke length.
That will give you a volume number to determine number of lock to lock turns based on size of the valve. Valves usually specify how much volume per turn of the input shaft.
Or (the easy way) you could figure out which cylinder bore/stroke you have and call PSC directly, they'll recommend the right size valve for your application.
You have a pump that will handle the pressure/volume? The Toyota pump probably isn't up to the task.
have you decided single end or double end ram? Single is cheaper, but has some getting used to as turns are 1/2 as many going one way as they are the other.
