Hey I just got in my MSD SCI ignition, I've heard it works a lot better with a external coil (i'd probably get the Blaster SS). Does anyone know if I really need it? I know I don't REALLY need it but does anyone know if it's worth the extra $45 to get one?

 

get it, the stock coil does not produce anywhere near the voltage an aftermarket coil can.

 

okay... when upgrading your ignition... what parts should you get? i mean like a list of the parts..... everything to do it right the first time...
