Fuel Rails for LS1 FAST 102
Fuel Rails for LS1 FAST 102 FAST 102 intake is going to be part of my MMS 220 build this spring, and I do not know which fuel rails would be best to get. What is the benefit to the FAST billet style fuel rails? The only info I can find says the billet are just for looks.
FAST 102 OEM style - 146021-KIT (around $240)
FAST ls1/LS6 Billet - 146032B-KIT + 54028-KIT (Around $318)
Also, I assume my SVO green-top injectors will fit properly?

This is an old thread, most of the pics are gone but still good information. I went back and looked at it to make sure I was going to make accurate statements about the rails.
Post #23 talks about using the factory style LS2 rails.

Depending on what injector and rail you use, you may need to use 2 different sized o rings.

Verdad Gallardo What about ID1050X injectors? Will those fit the FAST 102 intake? Those are the injectors that I plan on eventually. If those require the injector slots on the FAST 102 to be opened up, I might as well just open them up now.
I ran GM LS3 rails on my FAST 102. I have since gone back to a LS6 intake with my turbo build. Still have the rails, bolts, and spacers if you are interested in buying a used set with less than 1k miles on them. You can see my original build thread in the Gen 3 internal engine section for some pics.
