if you think the motor is stock,and has no intake or exhast manifolds.... if the engine has nto ben cracked open the easiest way to find ut if its a N/A or Turboed is ook into the exhst ports...

Do you see baffels?If so its N/A if not.. then you have a good chance its a Turboed,its you paid that much for a 6 port . im sorry..

Why didnt you take a pic of the car at the yard?Run a basic car fax on the VIN,it wil tell you what it is..
