Default Fast 102 Items for install
After searching around the internet and the forum on whether I need new fuel rails, injectors or injector spacers to insall a fast 102 on my LS2 Corvette, Ive seen very mixed answers.

Do I need different fuel rails, injectors or injector spacers to install a fast 102 intake on my LS2 C6 Corvette?

You should not need spacers or rails. If you use LS3/7 injectors, you need spacers, but not if you use LS2 injectors.

Thanks for the reply, My injectors are stock ls2 as are my fuel rails. So I should be good to go on just the fast 102. Thanks again

Yup! I put an LS3 top on my LS2 with a FAST and used my LS2 injectors and rails. Later, I upgraded to a strocked LS3 and I upgraded the injectors, so I had to use spacers. I ended up with Holley rails also, but stocker work. The fuel rail covers are an issue, but you can leave them off.

I went a couple different ways with covers.
First setup.

Looks awesome either way! Will I be able to use my stock covers with the fast? Ive heard of people trimming them and modifying them. I had my stock covers paint matched to my car so I would like to keep them.

Not sure of the difference between the ls2 covers and my ls6 but I just trimmed mine down with a dremel to fit

You can trim them, but I am not good at that kind of stuff!

My LS2 covers fit after just a bit of dremel work on a few areas to clear a couple runners on my fast ls2 intake.
