These are stock ion drives and fuel tanks, mostly just scaled up in case you want to save part count. The High voltage versions trade some electrical efficiency for some more power.
The thrust for the 3 of these drives is 10 KN,20 KN, or 100 KN, all using about the same power and Xenon per KN of thrust as stock ones.
The Xenon fuel tanks store 4000 for the radial High pressure, 6000 for the large normal, 7000 for the little one high pressure, and 60,000 for the large one, high pressure.
