To get a reliable bolt in kit between $3,000-$4,000. The only kits I would suggest are the Turbonetics, or Greddy. They are the absolute best as far as straight bolt-in kits. Our shop has NEVER had a problem with them and we have installed over 50 of these between the two. They bolt right in with no modifications and have everything you need including the fuel management so you take 10-12 hours to bolt it in check your connections and you are done.
