FAST 102 - What Do I Need?
yep, the manifold comes with the thicker orings for the bottom of the injectors. just need the rail kit, i got the kit because it comes with the braided crossover and the feed line
I have the kit that looks like a little bigger silver oe and connects right up to stock. 146021-kit.
Also, I forgot to mention you need to fabricate a bracket for your evap solenoid. I can post a pic of that if you're interested.

As I said in the General thread 'link' previous, use the 05/06 GTO LS2 water pump which has the same cone shape front pulley & you won't have to grind anything.
I had this issue in 2011 & found this pump solved the clearance issue.

What about the non return style ls2 rails?? The ls1 in an f body is a return style? How did you make it a return? I'm thinking a T firing because I'm planning on using
Nitrous on it.. Any helpful suggestions?

Okay I figured it out, corvette filter / regulator.. It's basically a fuel return lol.. And the wix one is no different from the GM one. I'm puttin it close to the fuel rail as possible so if there is any pressure drop it won't take that long to be corrected.
FAST 102:
ls2/3 rails
Your injectors will work but you will need injector adaptors, call Fuel injector connection (FIC)
Go with a 92mm TB. They are plenty and WAY easier to tune. With the 102 I've heard of issues hitting the water pump but that's an easy fix. Either way get a 92mm

Verdad Gallardo ^ You would figure the upper shell would be the same, but I received the kit that said LS3/7 and the mounting holes on the intake didn't line up with the rails. 
I honestly don't know why. Thunder Racing shows both P/N's now for the LS1 LSXr. One is for OEM style rails and the other is for Billet style rails. Not sure what the difference is. And for some reason I have a really hard time looking stuff up on the FAST site.
But those are the two part numbers I dealt with on my build.
