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.
Fast fuel rails work with their 102 intake

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

^ 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.

can the older style fast fuel rails part number FST-54023, work on the fast 102?
or do you have to run the new rails part number FST-146032-KIT which have 2 holes up front and 1 in the back.
