Crate Motor?

[HalM]

I am not sure if this is the correct forum for this question, so moderators please feel free to move as needed.

When reading forums and looking at For Sale ads for our 996’s, it is not unusual to see a car with a replacement engine. I am interested in understanding exactly what a “factory crate motor” is. Using my car as an example, it is a 1999 with a factory replacement built in December, 2005. How, if at all, does it differ from the original motor? Did it get any of the changes / improvements implemented in the M96 motor over the years?

Thanks in advance.

The factory replacement would carry all of the factory updates as of the time of its assembly. As a late 2005 engine, it probably carries the non serviceable IMS bearing found in some 2005 cars and all 2006 and later.

Although... the 1999 dual row IMS is just as strong as the larger single row that came in the 2005 reman, but now that can't be retrofitted without dismantling the engine. In other words, splitting the case.

Thanks guys. Much appreciated.

I have been under that impression for several years. But i asked because reading other forums, "experts" were saying things to the contrary.
