i'm running a turbo setup on a stock gsr motor. i have an msd btm but no coil. i see people run both the blaster 2 coil and the blaster coil ss, what is the difference and which would be a better combination in my set up? also my btm has the vortech logo and according to the manual, there is no megnetic pick up. ( purple and green wire that goes to the distrib., can i use the +/- as a megnetic pick up?)

 

anyone??
