So I've been talking to Brent (Sever) a lot lately about his future turbo build. The topic of Injectors came up, and I was told that 3S-GTE injectors can't/shouldn't/won't fit in a 5S-FE. Is this true, or is it just to much a pain to try and make them work. I guess this is just a little confusing for me due to the fact that I also own (aside from my Celica) a 1994 Civic, which still has the D16, and I'm running H22 injectors in that. I kind of assumed that since both engines were an "S" series Toyota engine, that more than just a turbo manifold and minor stuff would be able to bolt up to a 5S from a 3S.

If there is more of a logical reason than "to much fab" to make them work, can someone please enlighten me?

#1, the 3s rail dont fit the 5s head.
#2, the 3s rail is side feed , 5s top feed
#2 3s injectors are low impedance, 5s high impedance.
so no, like i told brent, 3s injectors will not work on a 5s.

alright, makes a helluva lot more sense now. Thanks for the imput!
