am running 19's in my 3.4 only .3 richer on my rteal time data system. keep in mind all the mods i.e. p&p, cam, & more displacement will lean the mixture so larger injecters might be a good thought. whats the part # on the regulator and is it adjustable. my speed shop guru says nobody makes 1 for the 3.4

i'm extremely interested in everything you just said. i'm going to be adding a cam, 1.6 rockers, and p&ping the heads, so will 19 lb injectors make it nice and stoich for me? i live in cali and cant be anywhere near .3 richer. :mad: </font>[/QUOTE]You better go conversative on the cam or you won't pass smog </font>[/QUOTE]huh? conversative? you mean conservative? lol. yeah i know thats the route i should go, better safe than sorry. as soon as i install this junk ima go smog test it and see how it is. i'm going to try and see if theres a way i can measure the a/f ratio and see how lean i'm going to be. since its only 2 lb more i dont think 19 is that bad...

I saw a compucam that was decent and passed smog, I can get the number from my dad.
Also, if you are worried about running rich, maybe get an MSD DIS-4?
I upped my fuel pressure by about 5 lbs and I am doing ok [img]smile.gif[/img]

yeah i've been considering the DIS-4. the cam i'm getting is an edelbrock performer plus with an LSA of 112, which should help me burn the fuel better. the lift by that way, after the 1.6s is .448/.472

[zbigdawg]

is the dis-4 worth it? does any body have a problem with a miss between 2400&3200 while pulling up through the gears? or have any ideas what it might be?

Yeah, i was going to have my stock 17's sent out and rebuild, but now i will run them once the cam is in, or just wait and see, then buy venom 19 hr. ones. i am afraid 19 hr injectors will cause me to run rich. can't i just boost the pressure with the regulator on the 17s and be ok. Viper, which do you have

I am running Ford Motorsports 19lb injectors. I have no problems with these since I can control the fuel pressure with my Holley regulator.

[whiteThunder]

have you tried your cam with the stock 17's josh? if so, what were your results? Second, i think they can grind out the vane more in the heads if i get 19 hr venom injectors, with of course a HOLLEY AF Pressure regulator.

[viper98885]

The car ran with the 17lb injectors. I put the 19's in there because if the future plans for nitrous at the time.

[whiteThunder]

So, if i am going N/A, should i stick with my stockers then? someone said something about bad spray patterns, so would venom be better(19 hr)?

[White95]

I would go with some 19lbs for NA

[oil pan 4]

19 would be good n/a, 22 if you do a hole lot of stuff to your car.

[NoRiceInside]

if i had 19s and then a dis-4 would that help the fuel efficiency and smogness?

[viper98885]

If you run bigger injectors, I would definitely suggest the DIS-4 so that you can be sure that all fuel is being ignited.

Injectors are now online if you want to check them out. V6--&gt;Fuel System--&gt;Fuel Injectors

i run 19's in my setup. i did some calculation and found that the 16# injectors (which are the ones that ive heard come with the 3.4.. 16# for 2.8/3.1/3.4) only support up to like 165 hp. past that and you'll need something bigger. you can get a set of 6 19lb/hr injectors from any 1997-200x Grand AM GT. thats where i got mine...and my intake, and my heads, etc...
