Did the e21 ever had the option to have power steering models previously?If yes than definitely you can.If not than maybe you still can.This is malaysia bolehland where all is possible.
My previous e30 came without the pwr steering option(uk import) but i managed to get all the required part locally and installed them myself diy....
Anything is possible... It's just engineering solution... Question is how much effort is required. and whether it's feasible...
Also the handling characteristic would be different... Sometimes worse instead of better. I guess it's the convenience to steer the car more easily at parking pace that you're considering a power steering. It might get too light at higher speed though..
Alex......if you are bringing in something from abroad....you might as well get your headers from there as well......UK ones are the correct ones to buy!
