'89 Accord LX - Rebuild or Swap Engine

I have a '89 Accord with 276000 miles on it. I would like to revive the car. Should I rebuild the engine that's in it or swap it with a different one? I would like a little more performance as well. I'm new to engine swaps in Honda. So what would fit, etc.... with the least work? Please help.

do u have the carburated engine in the LX or the Fuel Inejection engine from the LX-i.
