Slant 6 Turbo 68Dart Project

Well, I've done a lot of research, and it looks like there's an orange, black, and blue box that I see a lot of "opinions on" mainly "don't get an orange box, you don't need it" or get a blue, or get a black, or orange boxes suck, but everyone seems to agree that HEI is functional, so why not go with that. I gotta change something anyway, so why not make it functional.

I'm trying to cobble over the needed parts from slant6.org, but of course there are a lot of options and nothing simple. I'm thinking since I already have the electronic dizzy, I just need to get a better coil, and the HEI module, and run my wiring, and I'm good to go? Or am I missing something?
