Ok i'm thinking about getting the MSD Distributor w/Blaster2 coil but i don't know if i should get a BALLAST or not cuz i don't know what it is exactly.... i have a 88 CRX si motor, stock ignition if that helps... and also would it be hard to put in myself? and is that all i need? Distributor and Blaster 2 coil? HELP ASAP!!!!!!
