Outer Limits 4x4 Board

Ok guys im running an 80 series power steering box in my zuk buggy running 40 inch trepadors whilst its ok it would be nice to go hydro assist can pick up ram and lines cheaply but no info on were to drill and tap the box to pick up flow to the ram .Has anyone done this before or can some one put me onto someone who might know.

these same principles apply for all power steer setup. The box runs a 'power-head' (or "orbital valve" for want of a better description) this flow is then directed at either side of the "piston" (the bit that is on a ball screw and drives the sector shaft. so tapping into the cavities on either side will produces positive pressure once demand is placed on the steering shaft input. clear as mud!!

Thanks guys the box in the write up even though for a ifs hilux looks the same as the one of an 80 series

here is another nice write-up on a hilux IFS box.
