Ohh I completely agree with you on needing someone who knows what they are doing to handle the turbo and such. If I was to even try to do anything I would have a mechanic looking over my shoulder then go back over my work. If not to learn more about the system then to hopefully save a little on the man hr's I would have to pay for some one to do it all. But more then likely I will need to pay for someone to do it all for me anyway. I like knowing more about it though so I can understand and know what to ask. Thank you for your suggestions.
