2001-2004 will work with a 2002. Keep in mind the following:
A USA cluster is different than a Canadian cluster.
In 2002-2004 Porsche offered as an option a cluster that had a dot matrix middle display, if the car was made with the OBC option. Since you do not have the OBC option you do not have this dot matrix display. Look in the owners manual for pictures of the dot matrix OBC cluster.
If you do the retrofit on your car with the existing cluster then the OBC displays will look just like a 2001 with OBC. Your OBC display will not look like the OBC pictures in your 2002 manual because you do not have the optional cluster as your car did not come with OBC.
I do not understand why you would want to replace your cluster. They are very expensive. But if you do for whatever reason then consider a 996 cluster so that you will have the additional gauges.
