I know this is a bit out of place here but WHY? I dont get it, why would anyone want power steering on an 86?
Mate, I would've said exactly what you did a few months back, I use to pride my ae86 without powersteering. But once you drive one with powersteering, a whole new dimension is opened up (in the name of more illimination of understeer, ease of correction during overturning, and more of a range of turning circle)...
Sure the ae86 feels tough on high speed cornering without powersteering (which i love) but with the aided steering, it has the same credentials only your arms don't hurt during a parallel park!
