It's defiantly got 440s as I looked myself and a car mechanic has but would not know about the turbo as the cover still around the turbo and will need to do further investigation to find out. It still has its original recirculated dump valve which I'm very happy to leave alone and not change but just trying to find out if she been upgraded or came as she has and know now what to do if I want to up grade any think on her Ty for ur help on this
