The information contained within is given for use in research and readers enlightenment in making the many decisions available regarding the tuning and maintenance of the Alfa Giulietta car.  The writer in no way makes any claim or assumes any responsibility, that any or all the inclosed data is completely accurate. Only reliable repair manuals for the Alfa Giulietta such as GLENN'S and recognized Alfa experts such as Alfa Ricambi inc. and International Auto Parts, as well as your local Alfa professional, should be final word.... The other goal was to develop a format so that the reader may witness the development of the different spec. engines and models. This should allow one to more appreciate the model changes as well as decode and decipher for oneself the various changes made by the factory and others in your cars past history.  I have compiled this list from any and all references to the Giulietta that I could find. I however did not cover the special Giulietta's  such as the Sprint Speciale (saving some limited references), or the Zagato models, as each is beyond the scope of this work and would be a study within its self.
