Get a new clutch, get bigger 555 or 700cc injectors .. depending how much boost you want to run, a new fuel pump prob a walbro or a tomei one .. 275L/m or whatever it is.
But deff upgrade the fuel system, id also look into a oil cooler*
I'd also hunt down a Power FC or Haltec pc system, you will be able to run the injectors correctly for max responce and max reliablity!
you work fast dont you :S just saw your last post like a week ago bout the turbo :|
