Hey 1105, looks great!! I'm gathering parts to do the same thing. At the moment, gathering information more so than parts. I have 1 turbo at the moment and that's about it. I'm going back to school this summer where I'll have access to a welder and an awsome professor that used to be an engineer for boeing! (since my knowledge of turbos is limited to "wow...."). I know this is your post and all, but I was wondering if you get some time could you send me a parts list or something. Seems like you know what you're doing and I need all the help I can get. I can work on just about anything but I have never been exposed to turbo setups. Good luck with your project, hope everything works out for your and my sake. Oh yea, I've started plumbing a water injection system already as well. I've found quite a bit of info on it so far. Might be something you want to consider with a TT setup.
