Salam Brother
First of all please edit the post bcoz alto is 1000 cc not 100 cc (PAK VERSIONS)
Secondly, do not install EPS and power steering in non power cars, it will only cost you money and after that you will go to workshops every week.
Better Suggestion:
Sell out Alto 2009
Add some money and buy Japnese Alto 660cc with power options you are looking for.
Thank you
