We have a million and 15 suspension mods that we can do. Just about everything can be replaced with a better aftermarket version. You literally won't be able to stop. For mid 14's you'll probably be looking at I/H/E with a highflow cat or catless. Pullies/flywheel/Piggyback or Reflash. Not that hard. Trannies hold quite a bit even if you turbo it aslong as you don't go crazy with redline clutch dumps.
