well a supercharger would be by far the easier power adder all you have to do is bolt it on and route some belts but it takes power to make power with the supercharger but you have more low end power cause you don't have to wait for it to spool up like a turbo you get instant boost a turbo on the other hand you gotta get a different exhaust manifold you have to plumb the exhaust and you have to run a inter-cooler for more power but you have more high end power and it doesn't take power away from the engine like the supercharger but it all depends on what your gonna use it for a supercharger would probably be better for if your just driving it around and i would think it would last longer cause half of it is not gonna be glowing red from the exhaust heat but if your gonna be doing alot of racing and are a good driver i would say the turbo but there alot to think about when you us one
