Does anyone know about putting NO2 on a 03 cobra? And i just put in a spec stage 3 clutch, flywheel and it rcks. Also anyone know about the water pumps in my car, do they have metal blades or are they plastic. Only because my car started running hot and i tested my thermostat and it opened at a real hot temp and its a 180 thermostat. So i bought a new one and it still ran a little warm but the coolent was low so i have to check it again... Thanks a lot. Laters
