I'm excited to see you work through the ITB set-up. Be sure to post up what you learn so I don't make the same mistakes. That set-up looks pretty awesome.

I am excited, too! Just getting this engine built and in the car will be huge, as I'm also getting the exhaust done, plumbing AC and cruise control, more cooling powah and a bunch of other crap I opted to not do when I did my economy engine swap the first time around.

That's a great insight, thank you! I was just reading about the blended modes, and how everyone prefers it over just the TPS/Alpha-N. I saved the link.
Also....
I ordered my pistons! For anyone referencing this in the future (cough, empera), this is the setup needed for 10.5 CR on an M20 with S52 crank/rods with a 731 head with OS valves ordering through RaceTep:
JE 4032 Material Basic Set of 6 86mm x 89.6 x 135mm x 37cc, M20 Valves, 7-8 dish for 10.5 CR assuming a .070/1.8mm HG, 206mm deck height.
If you noticed....I bit the bullet and decided to go 86mm bore, as I'm not endurance racing this thing, and the price was exactly the same between 85mm and 86mm. The only functional difference is more powah and that I'll have to run a cometic HG.
This is the 3L I am swapping pistons in with the top end off showing the work. I'm going to sell these pistons for a deal for anyone looking to do a budget 3L m20. They have a special detonation resistant coating up top.

And this was the thick boi HG keeping the valves away from the pistons. Talk about whack compression height.
