1. Will stock cobalt SS/SC injectors/harness work on my ion?
2. IF SO, does anyone in calgary have the stock ones for sale?

 

I actually sold my stock injectors to a friend in town, who has a 2.4l cobalt, same engine as yours, so i'm sure it will work....and i really dont think u need the harness, but i could be very wrong...

 

ok thanks

any other insight into this anyone??

 

I had a 2.4 that I was going to do the same thing you are. I still have the Stock SS/SC injectors and the appropriate harness you need. $110 Shipped if you are interested.

Also I'm selling my TWM short throw shifter with the A6 Leopard knob for $180.

 

They will fit in an ION, but you need a different Harness.

The 2.4L harness has a different adapter to the main harness, and also has a connector to a Sensor on the end. None of these match up to the LSJ harness. Those injectors will work if you use a Ecotec Harness from an'04 Cavalier/sunfire. NONE of the Cobalt harnesses will work with those injectors.

And don't even think about splicing your harnesses together McGyver!

 

I got the exact part number mentioned in that HUGE thread about the swap.

 

This might be a stupid question... but, why do you want to put in the SS/SC injectors?

 

I did significant engine testing on the 2.4L motor and found that the stock 24# injectors are worked to their limits stock. And they can result in knock in the top end. If you try to adjust the timing tables at all in the top end you will immediately get knock.

By switching to the 34# injectors, you can raise the rev limiter a few hundred RPMS, and add about 3-4 degrees of timing to the table depending on how the car reacts. Even at their 40% larger size, they are not too big for the engine. Since they can be properly tuned, you can adjust them to flow the stock rate at any rpms, the difference is that they can keep up with the engines demands a lot better.

Stock IDC was over 100%. IDC after the injector swap maxed out at 76% That is actually a perfect operating range. They are better suited for the motors demands.

The swap is physically easy. The tuning is easy as well as long as you know what you are doing. Anyone else who has done it also knows that in about an hours time you can add a mod that gives your seat a kick in the pants.

In the Solstice I have had even better luck installing the 36# injectors from another motor. Those work like a charm, though are a LOT more expensive than a used set of 34# injectors from a dude on here.

The 34# injectors are not adequate for turbo or supercharging in the 2.4L, but they work ideally for the N/A setup. Whether you have other mods or not, you can notice an increase in performance. And in Comparison to any other bolt on, the injector/tune mod is by far the most useful, and will compliment your other mods.

 

thanks pysko, yea these injectors are jus for use until i have the turbo kit im putting together to give me that extra little power

 

You are tuning for them I hope?

Someone on a redline forum posted a thread documenting how you "don't" have to tune. He stated with a wideband how the car "learned" the injectors. Don't buy into that crap. DO NOT TAKE HIS ADVICE.

 

its gettin tuned..

 

Cool, it's so easy to do. Just setting the flow rate takes about 1 minute.

I'm sure you already had plans to tune it for more HP. Simply putting in the injectors and adjusting the flowrate will not add power. You just raise the Rev limiter to no more than 7250 (7150 is best for max), smooth out the VVT transition between ~4-5k rpms, and then add timing (about 3*). And if you are an automatic, you will need to spend a TON of time tuning that, unless you have done one before.

And be sure to remove torque management, no real need for that.

 

yup im having a guy do it for me

 

Just pray to god he knows what he is doing. Otherwise you can have a major headache on your hands, or see no gains at all. I'm sure you'll be fine though. The motors are simple to tune, you just have to know what to leave alone.

 

yea hes done quite a few around calgary for the cobalt and ion guys as well as the OBDI and OBDII, so im not worried.. i wrote down what you said jus in case too
