Redressing a controversial subject...

im thinking that my best option is the chrome Summit coil with 60,000 volts for $30
The best option is to learn from others around you or at a track local to you. Walk around, ask questions, take pictures. If you’re an engineer and just like creating stuff like this, more power to ya, but the solutions to simple tasks are usually pretty simple. And firing a plug on a small shot of nitrous ain’t that difficult.
