browse the site/forum and learn more about what u have in your hands...
like what boro said.. it's not honda... ae86's are pretty much the all go no show type of car...
if u gave us some more specific info we could direct u in the right way... but please realize you're not coming off as someone who's done their research or have the time and patience to deal with an ae86 (things break/rot/blow)
90% of body kits for the car are only available in Japan and if you've had experience importing a FBK from japan u know u'll be paying from 1500 usd and up...
use the money to put the motor in or get an lsd and some coil-overs/lateral rods
