question for anyone who knows, i am looking at buying the stock SS/SC injectors to put in my 2.2 i was told that they are 34#injectors and with a proper tune will help make more power.
could someone please describe to me how it acheives more power, what the tune does to make it, and what kind of power gains im looking at.
thanks!

 

the only thing i know about the ss s/c stock injector swap is for the 2.4L ss. BUT, they have to order your injector wiring harness to be able to use my injectors. so maybe your wiring harness will work, and you just need a tune.
good luck

 

without tuning they will probably hurt you, but if you can tune them i dont think your looking at more power without some mods.

 

mods like intake exhaust?
i didnt buy a full intake setup just a K&N dropin filter, i like the stock setup, i just bought pacestter headers should be installing this weekend, and the guy im buying them from is including the harness.

 

yes intake, FULL exhaust (header, dp, catback) and you would feel a difference.

 

any idea about HP gains...?

well i just bought them so i hope they improve a bit.
still would like to know gains if anyone else knows would be really helpful.
thanks!

 

couldnt tell you, but ive been thinking about doing the same thing. if not going to the 44# injectors. let me know what it does.

 

will do. kindof excited to see myself, although im going to have to wait for a tune. there is a meet at sonic in may some guy with HPtuners is going to be there charging for tunes. guess ill get it done then.

 

they have a tune for the 2.2 now?

 

Wrong, the Harness DOES NOT come out of a cobalt of ANY sorts! It is a 2.2L Ecotec from 2004 and older. There has been a big confusion about this, I'm just trying to clear it up.

You cannot TUNE for those injectors in the 2.2L yet because no software is available, but the older Ecotec harness will let you put them in your car. You should be able to Buy a MAF translator from Intense and trick them into working.

 

i have an 07 L61, i was under the impression that they would work in this motor

 

That harness doesn't matter, unless you are GOOD at splicing wires, then you could just rig the injector clips onto your stock harness.

My apologies, I will edit my above post. I meant that you cannot tune for those injectors in the 2.2L yet.

You can MAF translate them to work, which is pretty simple, but gives you NO HP gains. The power comes from the added RPM's, and timing, which is why the injectors are required in the first place.

The reason why the injectors are needed in the 2.4L is because they use the same injectors as the 2.2L, and are maxed out from the factory. I have not scanned a 2.2L because I can't, but I would guess that they are just fine with their stock injectors for now.

So you COULD make it work in the 2.2L because they will bolt in, with the older Ecotec harness, and the MAf translater would recalc the flow rate (essentially). Bigger injectors on their own will not give you HP, and without translatig or tuning you will be shooting LIQUID gas out of your tailpipe, because the LSJ injectors are 41% larger.

 

or hope sct's thing for the 2.2 works and they put it on the market to do the 2.2 soon.

 

so im confused what do i need to make the 2.0 ss/sc stock injectors work on my car?

 

We have not dyno'd the 2.4L but we saw a 0.5 sec improvment and +3 mph in 1/4 mile with a MILD tune and injector swap. That was on the 2.4L HP wise, probably 15hp with that setup.

 

but would i be able to tune to make more power? you say you cant scan it but im sure someone else has, i was reading a lot about maxing out the stock injectors, wouldn't an HPTune take care of that?

 

What I am trying to explain to you (as the guy who pioneered this whole setup in the first place) is that 2.2L motors are not HPTuners Capable. It is unfortunate that they have not tapped into that motor yet. You cannot scan it, and you cannot flash/tune it. Therefor, NO there is not a way to tune it for more HP yet. I understand that SCT (I think that's their name) is picking up the slack and making a portable tuner for the 2.2L

I can tune a 2.2L cavalier, but not a Cobalt! It's a crime! There is a large 2.2L community out there that could use some support with these tunes. As far as your 2.2L, It does NOT max out the stock injectors, based on intelligent calculations. The 2.4L does however.

I'm just trying to help you out by saving you some time. Keep your eyes peeled for the SCT (?) tuner, and look into a Dashhawk and see what that does, I don't think it tunes, but it reads.

 

i was told that HPTuners supports the 07 L61 motor in my cobalt. i was considering buying it myself specifically for that reason.

 

The real questions is do you need SS/SC injectors?

NO YOU DO NOT

Your no where close to maxing out your injectors with simple bolt ons. Until you bolt on some type of forced induction you WILL NOT need bigger injectors.

Bigger injectors dump more fuel into the engine, the engine can only handle so much fuel, you would actually FLOOD the engine and do harm with bigger injectors.

P.s. you have a pacesetter HEADER not headers

 

hmmm i was thinking about it since i do have the full exhaust(gmpp header,xtc dp, magnaflow catback),intake,lightweight crank pulley and comp cams stage one. and not that it matters much just ordered b&m shift plus. pulley and cams go on tuesday.

 

yeah header headers you know what i mean.
but other than that its still not what im asking, i want to know what would make them work. besides its good to have for when i do more mods. which as with most ppl are in the works, still working handling then im going to work on performance.

lol, well according to My06Coby you might be in need of them.
let me know if you find anymore info out that could be useful.

 

You DONT NEED THEM EITHER.

And to the original poster I was posting that so that you know not to put them on your car now. I can understand buying them for later down the road

 

yah most def. i got them for $50 with harness pretty good deal. had to jump on it. but its good to know that it wont be beneficial to put them on now.

 

since i dont need them yet i wont buy em yet. thanks all i needed to know.

 

you won't need the #42's without a turbo or a dry shot of nos. you're gonna flood your engine
*edit: you should not get a dry shot of nos though.. get a wet shot then you dont need to change the injectors
