Alright heres the deal.. i just bought my 89 mustang lx hatchback. its a 5.0 stick with only the exhast as a mod.. i think its a flowmaster offroad h-pipe or something (BTW, i dont know cars). ok the thing pulls very good however im interested in buying a turbo or supercharger. my questions would have to be... which ones better, what costs more, what would my hpwr be, and will alot of work have to be done to my stock stang in order for it to work? any advice would be very gratefull.. thanks.
