I currently have a 2005 Toyota Tacoma 4x4 2.7 motor (standard) that was hydro locked, I知 in the process of purchasing a motor to swap out, but I was wondering if I could convert to a 2005 Toyota Tacoma 4x4 4.0 motor (automatic) or (standard) without having to change out to much parts, and if so what would need to be changed out ?
