Nope you won't have issue with the steering getting heavy or the power steering pump unless you're not using a HICAS boss kit with an aftermarket steering. Just plug the power steering hoses going to the rear.
If the power steering pump fails, you can always opt to use a S13 steering rack with a SR20 power steering pump, which is rather easy to source.
