01 and ffdp thanks for the advice as it was very helpful. Dan, I need to put the engine in the car right away so this project does not sit. I have no more cash left for a few months. What are 605s? and I really like the supercharger so I want to keep it but a turbo sounds interesting. I don't think I want to install a turbo though just because of the lines and everything. FYI I have read the "Safely modding your 3800" several times over and will continue to read it. I have also read the diy tune and I took auto computer courses in college so I think I can hack it vs paying someone to do it. A tune costs about $350 but the equipment costs $500? When I get a few more paychecks in I can swing one of these.
