Just some quick info, no boiljoints are worn so I don't know what the other dude is on about, maybe a noob?
Basically with your belt off, you run the risk of increasing wear and tear on the power steering motor, this is connected to the steering knuckle and steering rack and forces hydraulic fluid in a lateral manner to move your track rod and ends. however it takes a very long time for it to fuck up

so you shouldn't have to worry about it. To be honest there are benefits of not having power steering, but depends on why you don't want it?
If you want the steering to be stiffer and more responsive, go out and buy yourself a DC2 steering rack and steering knuckle and have somebody fit it for you

it's what I'm doing soon and it's a lot better than the standard EG/EJ steering rack and to be honest you have more feel in steering in contrast.
all the best
