Electric powersteering?

There's quite a few options. The Saturn units are popular, as are the MR2 units. From there it's a matter of feeding it proper power and a speed signal. That last part would be the tough one, since our cars wouldn't have them standard, but there are plenty of ways to install one. A signal generator could be used in place of a speed sensor, but you'd lose the variable assist that comes from the speed sensor input.
