You going to be N/A I suppose? I would vote for a B18C5, the Type ARRGHH enigne. Or just a regual B18c...GSR engine.......But why not save some money and get a SC or Boost it.. Unless your really into making a N/A car......
And just incase your a ricer(not saying you are)...NO BODY KITS!

tegs look good with a small lip kit, but nothing too big
Wheels---Circuit 8's or slipstreams(sp?) are a few good rotas..IMO.....
My two cents........integra's are good cars, it'll treat you nice what ever you do...have fun
