Put a wanted post on for the pulley, loads floating around, or try C2 motorsport If you get a 6psi pulley, itll be fine if you keep it below 4000rpm, i drove around for 600miles on standard map If an 8psi pulley do the same and youll need red top injectors fitted at the place you get it mapped and i would fit water injection aswel worth fitting a low temp thermostat and thermostatically controled oil cooler with a charger too and youll need uprated engine mounts
