Swapping to an electric power steering pump?
Swapping to an electric power steering pump?
MK2 MR2 does as well. It also has a PAS controller which alters the assistance based on the speed of the car, and turns the pump off when there's no steering wheel movement (uses the steering wheel position sensor rather than a pressure switch which would have a delay).
Seen it done on a MK1 MR2 with a Corsa setup too, I think I linked you to that.
