new celica owner

hey guys i'm new to the forums, and i'm a new celica owner, i recently bought a 89 celica, or at least that's what the dude said, it runs kinda slow and it needs some body work, can anyone tell me how many if any major mods there are out there for a 89 celica gt and what kinda websites are out there for more info and/or parts for my car any input is appreciated,
