i need some help!?!?

im desperate for more hp but theres so many different directions to go. id love to add a turbo, around a 62-1 but theres a lot involved, ive done several turbo installs and id rather not try it on my car. reliability is an issue so i was thinkin maybe go with a supercharger?? ive been off and on thinkin this over for a while and i cant decide, maybe i should get heads and cams... then again you dont see much hp gain from that. im thinkin maybe kb twin screw and a diff cam right now? whats your 2 cents and what would you recomend i do for bang for the buck (no nitrous). thanx
