Ok guys I have FAST 102/102 intake and tb combo, also have a 224/224 cam, headers, air intake and full exhaust.. What injectors do u recommend? Stock? Or upgrade? Also what injectors work with the FAST 102? My stock ones don't seem to seat right and from what I'm seeing is I might need adapters or bigger orings??

The correct orings should have come with the fast. I'm a big fan of using oem injectors where possible. Ls3/7 injectors with top spacer kit from FIC (connection type) would work just fine. Or even ls2 injectors with no spacer kit. The ls3 give me headroom.

I bought the 102 used so I didn't get them.. Do u think my stock ls1 injectors with new orings are enough for my mods?? Or if I switch to ls2 do I need to change injector harness?

i had to go to 36# injectors with my 224r and LS6 intake

If you're stock injectors work with that setup then you need a new tuner :-). If you switch them out go ls3, about the same money or cheaper with more headroom. Fic has an adapter kit with spacers and adapters for like $100-$120.

^^^This you can usually scoop up used LS3 injectors fairly cheap and they are 42lbs, definitely leaves you some headroom
