ill be doing mine shortly, well soon... Hopefully. So this is what I'm doing for my SC14
First thing that need doing is the top mounting bracket, normally on the SC12, it sits and mount on the manifold, but with the SC14 it normally has a second bracket (well looks like it) to keep it against the block. So thats the first bracket that need to be made up. Apparently you can use the stock mounting pulley, but there have been some clearance issues with the inlet, so some people have moved it down, by getting a meaty piece of metal and simply shifting the mounts down.
So the top bracket should look something like this.
