I am looking into buying a nnbs/tbss intake, and found that tbss injectors are 29#'s, but what are the truck injectors rated at? also found a ls2 car injector will fit the rails, at 33lb/hr. any truth to that? I have 8.1 truck injectors in my stock rails at 31#'s, and I think I have read that they will fit in the nnbs/tbss fuel rails with no mods, they are the same height. is that true? also how about the flex fuel injectors?

 

no body? crap

 

yeah iv been looking for some info too for my turbo build on my nnbs right now all iv found is that house of boost has some direct fit injectors that are 52# that according there website fit the newer style truck intakes but not totally sure......maybe somone will chime in

 

My truck is a factory flex fuel truck my injectors i think are 38# but could be wrong....as for the 8.1 injectors i dont think it will fit there too tall the nnbs intakes take the new smaller injector i believe the same as the ls2's and the ones from the new v8 camaros

 

I remember reading the flex fuel nnbs had 37# injectors

the non flex fuel I would guess have a couple pounds less

 

Pretty sure the stock ones I pulled out of mine were 30lb.

 

I have read 30 too, but it was a guess. I thought some of you nnbs guys would know for sure. Truckmann had posted up that he used 8.1 injectors on his TBSS intake and said they were a direct fit. My injectors are short injectors. I am waiting on a PM back from him to confirm.
