Aside from the links to the factory service manual, there's not much for a guide that I know of for a d-series swap. Most D-series are basically drop in swaps. Some bracketry might need to be changed, but the blocks didn't change over the engine's life.

If you're going to use a d16a6, you'll have to do the DPFI to MPFI swap. It's not too difficult and there's a crap load of info on the net about that swap. Other than that a d16a6 drops right in.
