oh ok, without the y-pipe it makes it worth a lot less, i have seen kits go on e-bay for around 600-800 bucks and have everything to set them up. so to get 800 out of a kit that is missing a part that is needed as much as the y-pipe, someone would have to blow there turbo apart in frt of your house and need to get somewhere the next day (life or death) and you happen to have it. a more realistic price would prob be around 350 depending on how old the turbo kit is and what all parts are there, also banks stopped making parts to rebuild there turbo for the 6.9/7.3 and stopped making kits for them as well. can you post up some pics of what you do have and see what the part number is on the turbo so we know what you do have?
