Nikki carb modding
Thanks for the info. I turned my fuel pressure down to about 2 PSI on the gauge and it seems to have solved the problem. I put it through just about every kind of left hand turn and didn't feel it cut once. So with that problem cleared up, I'm going to call the SuperNikki *done* with stage 1. 
After all is said and done, the car is much faster and drives wonderfully around town as well. The only thing I might do differently in the future is to go a little smaller on the primary jets and make up the difference with the secondaries so my gas mileage doesn't take such a hit while cruising. For stage 2, I will be boost prepping it. But I have a lot of money to throw away and supporting mods to do before then so that one will have to wait
Also, I found more pics of the build process on another memory card, so I'll share a few more.

And here's some shots of my modified linkage. Cams for the cruise control and choke were all removed, as was everything else that wasn't needed to keep the spacing or serve some other purpose:

Trust us we aren't lying
Since we're on Nikkis, Just curious. Has anyone ever tried making a dual four barrel setup with Nikkis? Seems like the CFM of the stock carbs would work well for an engine with serious mods.
Great work in here.
Hey Lizard, since we are both in TN, would you want to mod one of my Nikki's for me
Seriously, if you do, PM me! I can ship it whenever, and I'll be in Knoxville on Nov. 5th for the MTSU v UT game (GO BLUE).

I could be persuaded, although I just started a blowthrough project on mine so I'm going to be pretty busy in the next couple months (or years, according to most of the turbo 12a threads I've read.) But if you're not in a hurry then maybe we can work something out. Feel free to PM me and we can discuss it further.
