Alright well I ordered some 52lb injectors from House of Boost the only ones that were a direct fit with the ev6 connector. Well been waiting about 3 weeks for them to come in and no go called them today and they said they were on back order. Oh well can't help that but talked to them about going with a dif injector and said it would be no prob. Question is what other injectors fit the nnbs truck intakes? They have some on there site that are 60lbers with the ev6 connector but they say they are "tall"? Will these fit? I imagine with some fuel rail spacers they should be good right? Also I already got my turbo on my truck and gonna be going with 10lbs of boost for the street and 15lbs at the track, these should be enough to feed my 5.3 right or should I go with there 85lbers? Thanks in advance I really can't wait to actually get on it right now the truck feels amazing on only 5lbs and stock flex fuel injectors and only in 1st and 2nd... Right now I'm only cruising around because at 5lbs my injectors are at 143% duty cycle at full boost. Really need some injectors and quick I want to see what my piggy really has! Lol

 

Anyone???

 

I have some 60# tall ls1 style injectors on my truck with the nnbs intake and rail. I just used some spacers and a longer bolt.

 

60's should be fine. There's plenty of guys on here making 500+ to the wheels with 58- 65lb injectors.

 

Hmm, are you running rich? I was able to run 10lbs on 42lb/hr injectors on my 5.3. I did keep my RPMs kinda low to save the old 4l60e though.

 

Cool just contacted my tuner and HOB I'm gonna go with the 85lb "tall" ev6 injectors so we have room to grow...

 

No I was starting to run real lean on the top end I think the flex fuel injectors are only 36lbers. Oh and I was only at 5.5lbs when they were going lean.

 

Sounds like a badass ride ya got there! Im jealous lol
