There is a lot of ways to go 9s in a Duster, but you asked for the best. Hands down, 572 pump gas Hemi. Red line it at 6800 and it will live forever, cheap to operate, huge resale value compared to anything else. And the whole range of 9's is available, from 9.000 on up. There really is not reason NOT to go with a Hemi.
