I have had a 96-00 Civic 1.5 Lsi D16Z6for a few months now and done some minor modding. Ive got an induction kit and header installed with a cat back system at the moment. What I want to know is what can I do to the engine to get the best prformance possible. Im considering changing the camshaft but some people have told me to swap the head and all sorts. If someone could help it would be much appreciated.
