thanks
You have the intake and the axle back which I'd say are the correct upgrades to start with. If you are still debating on either a supercharger or turbo then I'd hold off on the headers as Long tube won't work with a turbo but are ok with a supercharger, Short tubes however will work with both I think. How about lowering springs next ? that and the ported intake manifold are probably the next biggest items on the list. You won't get any power boost with the springs but you'll feel much better improvement in the handling and it gives the car a much better look with the lower stance. If you do the ported intake manifold, consider the intake spacer or isolator aswell at the same time.
good luck
