im kinda a noob to ecotecs.. but i would like to know what mods i could perform on my 2.2 i have a injen cold air intake and a custom exhaust i had made with a friend. i know header and downpipe can help. but what else can i do to get some more out of my 2.2 before supercharging and turbo?

 

Injectors, tb and intake mani, tune

I would definitely do the headers and downpipe first though

 

Injectors? Not to be mr. right but lap injectors are same p/n as le5

 

i was reading here that the manifold is the same as a 2.4 and a TB of a 08 2.4 would give a little more power. i got an 09 G5 so it would be the LAP 2.2 engine i believe

 

Not the same manifold as a 2.4. Injectors are unnecessary. 2.4 or LSJ throttle body, 2.4 intake manifold, header, downpipe, "custom exhaust" injen intake, lightweight pulleys. That's about it.

 

The LAP has the same IM as the LE5, but a different throttle body. You could also do cams, ac delete and other already mentioned things

 

all sounds good thanks guys i got 2.5" tubing on my exhaust is that ok? and ac delete not good for texas weather lol. but ill look into the throttle body. will i need a tune after?

 

The 2.2 LAP intake manifold is a modified version of the 2.4's. So technically you don't need to replace the intake manifold, you got about the best there is already. Not sure about the injectors, but if thats true that they are the le5 injectors that rocks too. I'd do full exhaust, intake (you already have), TB, and tune.

 

2.5 inch tubing is fine for your exhaust. You have the new style 2.4 IM so no need to change that. Throttle body would help some and you will need a tune for that. Injectors won't do anything for you because to use more fuel you need to flow a lot more air which won't happen without forced induction. Do header and downpipe first then throttle body and tune. After that you are pretty much out of options except to go turbo, supercharged, or run nitrous

 

I was under the impression that a slight injector upgrade could help. *shrug*

 

Nope. My injectors are 75% IDC with all my current mods

 

If you are an auto you can throw a B&M shiftplus on it. Mounts also make it feel a little sportier, little better response

I can't speak from experience yet, but IMO just go super or turbo

 

I will be getting mounts soon...they worth it?

 

Only if you max out the stockers and that would take a serious N/A build to do that.

 

As long as you don't mind the vibrations. They are pretty bad at first but die down after a few weeks. Car feels a lot more responsive with them on.

What are our stock injectors good to?

 

No idea. I think they are like 24# injectors or somewhere close to that. I would say you would need cams and serious head porting to max them out N/A though

 

Ok so next I'm doing header and downpipe and then TB.. I was planning on cams but I would need to tune correct? And im planning to go supercharged sometime but not any time soon that would be last on my list.

Also what do better mounts do? Do they stop all the vibration I get when I have my AC on?

 

You would wanna get a tune regardless...then you can go over 115 mph!

 

What is this shiftplus? Ive never heard of it and i researched it a little and from what i can tell whats the difference between that and just a tune?

 

I got my car to 125mph and it wouldn't go more lol

 

Cams are not really worth the hassle unless you go turbo or super and are looking to optimize the setup. Because of the variable valve timing I'm not sure anyone even makes cams for the LAP but the last I read someone talking about doing cams it was gonna cost over a grand because of custom work needed to make it work with the VVT and to get the "key" on the end for the cam sensor.

Mounts will stiffen up the engine so that you put more power to the ground and don't get wheel hop.

 

oh i see. oh well then no cams for me

ok so with mounts will help get me a better launch?

 

That's what they are supposed to do. All my mounts are stock so I can't tell you whether they make a difference or not.

 

Oh ok its cool and I bet I would get smoother shifting too?

BTW what header and downpipe do you suggest?

 

If you have the money and want excellent quality, I'd go with the ZZP long tube header package. I've had mine with catted downpipe since august and I was still N/A when I put it on. It is a wonderful setup and you can feel quite a difference with it, especially up in the higher rpm range. It makes the exhaust quite loud at WOT though. I like the way it sounds, and that's the only thing that could be considered a downside with the combo.
