Mazda 3 2.0 liter Turbo Camshafts?

[Huami]

hi, I turboed my mazda 3 2.0 Liter engine now running at 200whp, want to get more power out of the little beast but I have to change my stock camshafts, anyone know where I can buy an aftermarket one built for turbo applications?

my tranny from lenntech automatics street terminator with a gt28 turbine currently running at .6 bar boost

thanks all ^_^
