A friend of mine brought his car back to bone stock form, and gave me his DIS-2 HO. I know if I go with an MSD set up I'll need the DIS-2 for the trailing plugs and a 6 series for the leadings. I dont have a 6 series one at the momment. If I went ahead and hooked up the DIS-2 HO to the trainling coils now would that hurt anything, or woudl that cause some strange temporal flux right? Where are some good places to mount it?
