I want to kick up the ignition on my car. I've thought of using the MSD blaster2 coil with 45,000V output. My question is; what size ballast resistor should I use with it? SpecialTauto has 1.8ohm resistors for the 25,000V coil. While the MSD blaster2 coils come with a 0.8ohm resistor, which they state "will fit most applications". Would the 0.8ohm or the 1.8ohm work for hte 45,000V coil, or do I need an even larger resistor?
