theyre 17# instead of #15, but you can get #17 injectors from a 3.4, or better yet #19 SVO injectors, you can find sets of those for cheap all over ebay(and at GM fuel pressures they flow more like 21/22 lbs). What kind of HP are you making, and are you planning on tuning the ECM to adjust for the injectors(or just a fmu)?

 

well im gonna go with fmu for now, which if what ive been told is right,i wont need the fmu till i pass the 7psi mark,
with that said i was also told the stock injectors would be fine with an fmu upto about 10 psi but lock up above 72psi fp
so i was thinking slightly larger injector with slightly less fp

 

I got some ones rob suggested. 18.55 lbs out of a buick. They were hard to find, but the easy ones to find are 18.1 IIRC.

Very quiet too!!

 

hmm wait, i just noticed some inconsistencies in my post lol . . . 3.4 injectors are #17, i dont know for sure what size 3.1's are, i know they arent 17 though. i think maybe 15 and 2.8s are like 14 or something . . .

i dont know that much about fmu'ing these injectors, my plan is either tuning the ecm for the injectors or maybe running a stealth megasquirt setup but keeping the old ecu for easy emissions testing (if i build the MS stuff myself it ends up costing about the same as tuning equipment for the stock ecm, but its a crapload better and is still easier/cheaper than switching to 730 or 749 . . . especially if i want to keep everything else stock). FMU's seem to be a little guessworky anyways, so i would step up an injector size or two anyway just to be on the safe(rich) side.

 

dale willing to sell them?

 

No, I'm running them But they came in buick um, ****....The FWD 3.8. They look totally different then ours. I posted a picture of them in my recent thread.

If you need the part number, let me know as I can easly view it right now.
