Unless you have a 2005 or later, you cannot get the OEM unit as Porsche will only sell you their "final solution" large bearing assembly, complete with a new shaft (required) for a bit north of $1K. Then you get to take your entire engine apart to install it.

Long before I would even think about using another steel bearing, I would opt for the highly successful LN ceramic unit; anything else is purely false economy............
