Thanks for the swift responses guys...
The vehicle in question is a 91 civic dx. I purchased it as a shell and all wiring was intact, and had 125k on the clock. I usually here people say stock ignition on their newer vehicles. For example Trip, and probably 60-1Ek as well as the rest of you. The motor is fully rebuilt, and capable of handling upwards of 20psi. This is a SOHC Vtec. Im just trying to see if I will need the added spark or not. Of course I want the cost effective route, but I want to have what I need to get the most out of my setup. I hope that is understandable. I found a guy selling a MSD SCI for 125, for just the box but I would still need a coil, wires, and a cap. Or maybe I could just use a blaster 2 or 3 coil with a msd cap? any further insight?
