how much does it cost and what parts are needed

VS racing has some pretty good package deals. Depending on what size turbo you want to use. One for my 340 is $868 for turbo, inter cooler and piping, waste gate, blow off valve, t4 flange, oil feed and drain lines, and turbo discharge and clamp, bigger turbo is couple hundred or so more depending on size. Then its fuel system, boost referenced fuel regulator. The hot side, I am using magnum manifolds, turbo carb bonnet, and I am assuming blow threw carb you do your self, and somethng to pull timing under boost. Also a wideband to help tune is a good idea. I think I can get mine done for around $1600 or less in parts, thats doing all the work myself.
