quick fast 90 question...
quick fast 90 question... so i have an LS2 GTO and i just bought a fast 90 intake from a member, seems i need a different fuel rail correct? anyone got a link to a previous post concerning this? i searched my *** off and either suck or there isnt one. thanks guys.
im pretty sure you dont need another fuel rail. stock rails should fit without a problem. its if you get a fast 102 you need to switch rails
LS2 GTO requires a conversion kit for the OEM fuel rails to fit. Its part number #54026, I used to run it myself. Ill look and see if I still have it laying around in the garage.
Id look in the calssifieds too.

Is it possible you can update us when you get it on. I would like to know about your gains, since I have basically the same mods as you.
You should be able to use the LS1 injector o-rings to get the rail to clear. Instead of the adapter kit from FAST you can use a washer to bridge the gap where the rail doesnt meet the intake. It will save you some cash and it will still work.
I have the LS2 corvette. The motor and fuel rail is the same. I just installed my fast with LS1 injector o-rings and used washers to hold the rail down. I know the holes dont line up but with the right size washer it will overlap the tab on the fuel rail.

The 102mm FAST will work with washers, possibly, because it has an LS2 bolt pattern. THis is asking about the 90mm.
He needs to order the kit, I ran myself on the intake in my sig pic. You can see the silver LS2 OEM fuel rail and the 92mm FAST.

Verdad Gallardo I have a FAST 92. The bolt pattern is the same as a 90 because they were made for the LS1. Im telling you for 8 dollars in hard ware and the LS1 injector o-rings you can hold the fuel rail down and it will clear the manifold. If your picky about looks order the 80 dollar adapter kit.
