Find out what kinda of engine you have. It has to be a Honda Engine. So find out what engine is in your Del Sol and then find out what engine came in the honda civic in 1993. And if both cars have the same engine then yes you could. Some parts might not match because of available space under the hood or under the car. Like a cold air intake or a Cat-back System. But you could definately get headers, downpipe, ECU upgrade, Universal Muffler, KandN airfilter, Intake Manifold, and internal engine parts.
