RE: The Plan
Yes, for the slightly larger front-end investment you get a system that is infinetely more reliable, performs better, and won't give you headaches. Been there, done that. You will end up spending the extra money within months buying new coils because you keep burning them up. Most everyone on this forum(except RC1IGN and tkg) would love an inexpensive alternative, including me, but I haven't found one yet. The CH and RC Ignition systems I do have have never given me trouble and that is worth some $ in my book.
Try going back and searching for TIM-6 on this forum. There is a lot of info if you're willing to look for it. Hope this helps.
