parts with $600

i have 600 dollars to spend right now and i want some more power on my take off i have a lancer es any ideas thanks

The biggest bang for the buck would be Nitrous. With $600, you might be able to get the kit installed, and still have a bit left over for a couple refills.

i guess i should have been more detailed i want mods i can use in the city so nos wont go well with what im lookin for if it matter i already have the k&n intake as well as the magnaflow cat back the rest of my mods are looks now i wanna start on the engine more

i think that you should save up some more money and get a turbo from www.roadracemotorsports.com or get a supercharger from ripp motorsports. that is what i would do.
