I found a guy who will sell me the motor in this picture but he is unsure of the year and the water pump assebly and neck look different from what I've seen before. Any help figuring out what it is would be appreciated.

 

I bought the motor and am still trying to figure it out so here are some better pictures. From what I can tell I think it's a S4 with a S5 front cover on it, but would like some confirmation if anyone knows for sure. There are motor mounts underneath, and not on the front, so I know it's an 86 or newer.

 

yeah , I would say it is a 1986-88 NA FC motor.

 

Yeah, it's an S4 based on the thermostat housing cover.

Not sure if that's a OMP eliminator kit on the engine though.
