first things first; budget, custom, and quality do not go in the same sentence when talking about turbo kits. if you were to get a quality custom turbo kit, it would cost you about twice as much as to buy something from Greddy or Revhard.

After working with my friend installing his Revhard Stage II kit in his LS, i highly recommend it. with the tial wastegate upgrade, and it comes with FMIC.
