I would probably try it with the knowledge that the morning sun would be the limiting factor on success. KBG is not a shade loving plant. Most zoysia is not shade loving either. There are two zoysia varieties, Diamond and Shadow Turf, which do very well in the shade and sun.

dchall, thanks for your input. i also worry about the water requirements for KBG in eastern NC, it gets very hot here. The portion of my yard that needs replacing receives sun until about noon or 1 pm.
thanks,

Coastalnc, I'm in Raleigh, KBG can be found mixed with Tall Fescue in almost every lawn in Central NC. It does well, and in places where there's irrigations, it outcompetes Fescue very easily.

Your morning sun and afternoon shade will enough for KBG to grow with good success if irrigation is provided.

If the area is not too large, get Sod instead and if budget allowes, too.

Your sandy soils will make KBG thristy during the summer, but it can go dormant (not fully brown like Centipede or Bermuda) and save itself in the process. When moisture returns, it will green back up.

It is a very pretty grass, I think you should try it.

If auteck says you have enough sun, then you're on the way. Give it a try. Check these guys for seed and especially the Bedazzled variety for your area.

To better help your choice of cultivars I suggest you look at the latest NTEP results for KBG in the transition area, particularly at the North Carolina location. http://www.ntep.org/data/kb05/kb05_09-10/kb05_09-10.pdf go to page twenty. Seems like the top one in NC is Nuglade, followed closely by Rhapsody and Shiraz. There are about a dozen that are close together in the 7's, which is definitely nice turf. You then might want to read their tech sheets to see which ones have the best shade tolerences, and heat/drought tolerences. Then you can make up your own mix if you want. Bedazzled wasn't included in the latest trials, but it was in the last one, where is was midpack in North Carolina.

I was extrapolating from a very short list. tiemco's link is a good one.
