A proper turbo setup will overcome the low end lag and also be better on the top end. The supercharger will just get in the way and reduce flow at some point and add drag to the engine because of the belt. Either turbo it or supercharge it, not both. My cousin's husband runs his own repair garage doing mostly Honda stuff but he installed a supercharger setup on a customer's Miata and he said it ran pretty strong like that. There wasn't much room to work with, but then most of today's cars don't have any room in the engine compartment. Oh, and a turbo does transfer heat to the intake side to some extent. The setup in that picture is looking for trouble with a turbo pumping directly into a supercharger with no intercooler? Run away from that cr@p.
