I have a project to work on and well I need some help. My brother and I want to build a mustang that can be upgraded and or tuned to hit the 1k hp mark. I know my '98 V6 just doesn't have it in him even though he is well taken care of. I want to know what would be the best model to start out with wether it be a GT, Shelby, Roush, or Saleen. I already know that whatever one is the best option can't already have a supercharger since we are going to twin turbo it. Just need some help from a more experienced crowd I suppose.

Thanks.
