man if i was u, as FstFwd said. Kep it as a starter kit and start replacing stuff as you go alonng. you can always send the turbo to get garrett internals, or jsut buy a new turbo.
you can get the manifold rienforced etc. this is you will be using double you money lol.
i have been researching parts for months now and am building a custom kit to suit what i want cost and power wise. good luck though :)
