A carbureted car increases fuel levels with the use of a boost sensitive fuel pressure regulator. The pressure regulator keeps the fuel pressure a few psi ahead of the boost pressure. For more indepth information on making a turbo kit get the book "turbomania." It covers everything from turbo selection to carburetor modification. I wish I could be more helpfull but my friend borrowed my turbomania book and I haven't seen it since. Hope that helped.
