Supercharger?
 

I have a 1990 N/A and was wondering if I could centrfugal supercharge it. I reall dont want to turbo because I think they cause more reliability issues. Has anybody done this, what can In expect for power increases?

Try a search for "supercharger". This (as have turbo issues) has been covered thousands times. Lots of info available.

Any boost on any engine causes reliability issues. An engine will ALWAYS run longer naturally aspirated.

thanks, i know both will cause reliability issues, but has anybody done, and how much power increase van i look at?
