Retro Fit Power Steering

Hi all,

I am new to this club so first hi to everybody.

I used to own a k11 red micra a couple of years ago (i went from a 300zx to the micra!). To be honest i loved the car but i have since moved no to a different car now.

I am posting because i have the chance to buy a k11 for my girlfriend. Its sounds like a cracking example. Its like new with only 5k miles on the clock. But it doesnt have power steering.

Can power steering be retro fitted and if so, how easy is it to do it?

Thanks in advance.
