This guy buys parts for his car but mechanics do the work. He bought some turbos and stuff years back that had to be returned and in the mean time just paid again and got a new turbo shipped out, while the other was replaced. He ended up with two turbos one got installed the other is still in the bag, brand new. He couldnt remember for sure what he bought, but he rememberd one being bigger than the other. He ended up getting two 53's two 51's or one of each. He's not even sure which one finally got put on the car, he just knows its fast. Any way the one in his attic is brand new in the bag from PTE. It even had the packing slip, which didnt help it said PT 51>53 on the slip. I didnt open the bag yet but all I know is that it said .60 on the turbo housing, and said precission on the exhaust housing. But, so did the one on his car. It is the complete turbo with adjustable actuator and housing that connects to the down pipe. He said it was 800 bucks. And is looking to sell it. But neither of us can figure out whats what. Is there some way to tell for sure. And is the price good at 800 for the complete setup. Thanks
