Help in Redstone

Have you considered using Copper Golems, or is this a bulk sorter? If so, try to build it across the chunk boundaries, use chest-minecarts/water streams to cut down on hoppers.

A simple item sorter takes 2 funnels per item, so you can sort 16 things in a chunk with those rules! :3

If you keep the item line going into the next chunk you can build more filters and sort another 16 items there. Basically it all depends how you set your storage boxes up, cause with the rules it's very hard (but not impossible) to have stacked item sorters if that's even what you mean.

edit: i dont really know how to help without lots more info

Assuming "funnels" means hoppers, the most straightforward way around the limit is to build the sorter across chunk boundaries. [​use f3+g]

If one uses water streams to transport the items to be sorted, one needs only two hoppers per ply (sorting station). https://minecraft.wiki/w/Tutorial:Hopper#Overflow_protection
Placing the sorter so those two hoppers are on the edge of one chunk (e.g. the north) and with the output chests (and any associated hoppers) in the southern part of the next chunk north would allow 16 plys per chunk.
The mechanism to inject the items into the water stream would need to be in the chunk 'upstream'.
