Ok lets start with the power you will need for 4 Level 6s. MINIMUM 2 10ks. Now to properly run 2 10ks, you are going to need somewhere in the neighborhood of 10-12 d3100s unless you can fit 3 alts on your car. Where are the amps and batteries going to go? I would be more than happy to help you out if you are seriously trying to pull this off, but I just really can see how it would physically work.
I am not bashing, I just dont think you know what you are getting into. You are talking about a 25k build here if you do it right.
