I have a 2007 2.2L Cobalt LT stock engine. I do not know what gen it is. I'm guessing gen 2 but I could be wrong. I do have some experience with engine so I'm not a total noob. I want to work to know:
Spark plugs
Can I use stage 2 colder plugs?
What is a good brand?

Cams
Can I use cams that will keep my valves open longer on a stock engine?
and can I use a 2.4L head on a 2.2l engine?

 

there's no point in colder spark plugs unless you boost it. there's no point in cams because you would need a full intake/exhaust upgrade to even notice a slight difference. changing to a 2.4 head if even possible (never looked into it) wouldn't be worth it because it's not any more durable, mainly same parts besides possibly different cams. don't think it would bolt up.

 

Ok that makes sence. for the exaust, if i got a 2.5" or 3" header, down pipe, and muffler would this have any negitive effect on the stock engine. also a lager intake.

 

2.5 all the way around at most. injen CAI has the option of being CAI or SRI, so i'd go with that. if you plan on going boosted anytime soon, restraint from buying an intake because you'll have to buy another one down the road anyways

 

now what is SRI?

 

Short RAM intake

 

i think i might go with the 2.5" intake and exhust for now. just a lil more power the exhust mor then anything casue ill be goin with a super charger.

 

also what is the difference between a LSJ and a LNF engine and how can i tell which one is mine?

 

LSJ = factory supercharged 2.0L
LNF = factory turbocharged 2.0L

You don't have either. You have an L61 2.2L

 

thanx.

 

Yeah, you know a lot about cars and motors. So much that you can't even tell when you don't have forced induction.

 

i have a 2.4l mani for sale

 

^ says the guy who says he has a 06 radio in his E37 07..........

 

not me

 

Yeah i know not you. You hit submit before i did.

 

Ha. I deserve that.

 

However.... there is a huge difference in confusing radios and confusing having an intercooler/heatexchanger, a bigass twin helix blower, a manifold with a snail thingy on it, not SS badges... hell on the front of the forum it indicated MY/engines. I don't see how he was even able to navigate to this section without knowing. That's like confusing your own EJ20 impreza for an EJ25 STi, or confusing the 3.7 new Mustang engine for a 5.4L supercharger GT500. Just saying. I know I'm an idiot but still.

 

cams are a no

 

Back to the point ;P

 

Fully bolted would they make a difference?

 

no i said i no a little. i know i didnt have forced injection hence y would i said i plan to put a supercharger on it. just casue i dont no the alphabet soupe is done mean i no nothing.

 

Forced Injection Lulz

 

sry induction

 

i was looking on ZZP and alot of it said for LSJ and LNF and had no idea what all that ment. i just what to do little mods to the car before tearing open the engine to add the super charger.

 

To get back on subject.No the LE5(2.4VVT) head will not work on your motor.It will physically bolt up,but would be pointless since you couldn't run the VVT actuators.You would have to do a complete harness swap and ECU swap for that to work.You are also a gen2.As stated above,Colder plugs are not needed for N/A.If you go F/I,1 to 2 steps colder is best.Camming is nearly impossible thanks to the intake cam position sensor.There are a set of Comp stage 2 cams with the sensor floating around somewhere,but they have never been tuned in right(assuming whoever machined the sensor on,didn't line it up perfectly)My fingers are tired.I'm done typing lol
