My friend has a d16z6 and he is wondering which one would be better....A turbo or a supercharger....He is really clues as to which one to use....so any kind of info would help him........Hes putting it a 91 civic

 

Do a search. Make sure you look under archived topics, its been covered plenty. Anyway, it depends on what his goals are.
Turbo, many options to expand
Supercharger, limited

Peace
