Ok so I’m new to the diesel world, just bout an early 99 model 7.3 f250. So the guy I bought it from inherited it from his father who passed away recently. The father had put a lot of money into this truck. Everytime I look around I find another banks performance part. I mean there’s all kinds of banks stuff. So that being said I am not sure of what all is in this truck. My question is, does anyone know if this turbo is aftermarket or just stock Garrett with upgraded parts? The hot side is a banks housing and the cold side doesn’t look like the other Garrett’s ie seen on stock trucks. Is there any way I can look it up by serial #?
