I brought the ol SS into the shop to have the fast 92mm intake and throttle body installed. They called me and told me they put the 102 on saying that fast discountinued the 92 for the ls1. Has anyone heard of this yet? Btw with the ls1 do you need new fuel rails with the fast instake? Any feedback for me would be nice thanks.

no, you do not have to use new fuel rails unless you just want to upgrade, the stockers fit fine. a for as I know you can still get the 92mm I think they are just feeding you a line man

Thats not what Ive been being told. What 92's are out there is all thats left. The 102 is all they are making now. One of the vendors on here told me they are done making 92's. I believe it was Jeff from Spectacle Solutions in another thread. Again I cant confirm this as I dont work for Fast,but Ive been told a few times thats whats going on.

I went to the site and found that it is true they dont sell them anymore. The place that had my car upgraded me to the 102mm lsxr manifold. With those you do need the ls1 fuel rails because the stock ls1 manifold had a slot on top for the fuel rail to cross over. The lsxr however does not which meant i needed the ls2 fuel rails. So Fast is no longer selling/making the 92 so if you want one get one before they are gone

I hear the 102's flow like a ported 90/92 Ron at Vengeance has a thread up where he is going to do some head to head testing. Should be interesting.....

So what did ya do with the fuel rails? Buy LS2 rails? is that all that is needed? I couldnt find a 92mm anywhere. Just bought a 102mm.

What about these? Could you make them work? Or what about if I just got an LS2 fuel rail set up used? Whats with the spacers that come in that kit?
