First of all, Welcome to HS
The power estimate will be a rough one...
Before you do any of the fuel mods, make sure you either have custom 2-1/4" piping to your muffler, or get a full cat-back system. Also, I'd get a good header. Now your airflow should be doing better.
If you're dying to spend all of that cash on the fuel delivery system, AEM makes good components, but I'm not sure you'll need all of that (anyone else want to comment?)
Have you ever conisdered an H22A engine swap instead of dumping all of this money on your current engine?
