UrbanFuturistic, the 3.0L **was** available in the 944.

From '89 to '91 the 208hp 3.0L was available in the S2 coupe, which had the styling of the turbo. The base coupe was bumped to 2.7L, 162hp. I guarantee this car exists, I've seen them with my own eyes, and my uncle has worked on several of them.

The 968 didn't appear until 1992, after the demise of the 944.
