Cheap coils are cheap. You guys probably wouldnt pay 500$ for this setup if i said it had msd coils on it. The cheap coils have worked so far but im not putting alot of stock in the coil. How many people have bought junk yard IS coils because new ones are to expensive. The great old saying, speed costs, how fast do you want to go. I could post up all the info i have on the setup and let every one build their own. Im not trying to make a living off this just share with the community and if you want me to build on for you i can. If you want better coils, buy better coils. Its what this is capable of that is the big point.
