Versa 2009 1.8s hatch

hey guys i got a versa about a year ago it is a 2009, i am planning to do some upgrades, and i would like advice on stuff to change to make it, fast, and more fun to drive, its an automatic (sadly) but oh well, i already got wider tires (205 instead of 185) changed the radio and speakers, but i want to maybe put a cruise control on it, and anything to get the performance up. Any suggestions? please feel free to give me ideas and stuff

Thanks
