My buddy bought a used TT kit of here that was supposed to be a direct bolt kit from hennessey. The for sale ad has already been taken down, but the guy said he was throwing in new turbos as if he was doing my buddy a favor! Long story short, with these turbos combined w/the piping it will be impossible to make the "bolt on" hennessey kit work. I think if we could figure out what turbos hennessey originally used, then we could make the piping work. Otherwise, he'll be starting from scratch w/fabrication of hot parts! Any help is appreciated!!! Thanks--Andy
