I have a NA 3800 bottom end so ill just use that. Here is my list just chime in for any help. Na 3800 bottom end, Power log, vs cam, zzp 1.01 computer, u-bend delete, i have a friend who does turbos and said hed do a air/air intercooler for me. Is an intercooler an overkill at this level? Use stock pulley or go down a size? Realistic horsepower numbers 260 to 270?
