Project Fat Nikki

I've procured an 85 nikki and intake manifold from pullapart for some fun.
My goal is to hog out this nikki to the best of my abilities so that it can be used in
place of my current Dellorto setup. I have no compelling reason to do this, the
Dell works great. I just thought it would be fun to do. It will initially go on my
stock port 12A.

I'm cleaning and disassembling right now and will get pictures up as I go along
making the various mods. I know I could get a sterling (maybe) or from SR
Motorsports but I want to do it myself.

So I'll post my detailed plan for the modifications to be done. Please feel free
to post up anything I may be missing or can do better or have first hand
knowledge about that can help me out. In return I promise to deliver lots
of details and pictures as I go along.

Heres the plan. I've numbered each step uniquely and grouped then logically
by component to make discussions easier. If nothing else I hope this helps
anyone else contemplating hogging out their nikki.
