My apologies if this has been answered previously.  I have a Windows 2008 Enterprise server configured with Failover Clustering.  I also have (2) separate Window 2008 R2 Enterprise servers configured.  Is it possible to add the 2008 R2 nodes to the 2008 cluster?

Failover clustering will need to run the same version of Server edition. Plus their are enchancements in R2 that Release 1 doesn't have. So, in short the answer would be no.

In the first peek I say no too...

but maybe can... beacuse the cluster was 2008, and the plus R2 enchancements dont apply in the node...

No. You can't have a mix of Server 2008 and Server 2008 R2 nodes in a cluster. You need to create a new Windows Server 2008 R2 cluster and then migrate resources from the Windows 2008 cluster. If you don't have new hardware, remove nodes from the existing cluster, rebuild them with Windows 2008 R2, then create a new cluster and migrate resources.
