I wanted to know if I can do this without problems... According to some threads here at css, the LAP head is different than the L61 head in the way the SAI is routed, basically it has 2 ports in the LAP head. I've searched and found 1 individual (Gene Culley) installed an LSJ manifold on the LAP, and had to modify/cut the manifold. But, that manifold has gaps between the primaries, where the Badmab header has a flat piece of steel (flange???) that mates to the head. So would that flat piece of steel on the header just block off those 2 SAI ports on the LAP head, and I'll be ok??? That is in addition to tuning out and physically removing the SAI.

 

Idk what an SAI is, otherwise I could probably help you. Are you boosting or N/A

 

I'm NA. SAI is secondary air induction. Here's a thread on it with the L61 2.2s: https://www.cobaltss.net/forums/2-2l...06-l61s-38488/

 

So your LAP has SAI? By the looks of it the badmab should cover the SAI ports, but you will most likely have to delete a code.

Take the heat shield off and take a pic oh the manifold

 

That's almost impossible with the SAI sitting right above the exhaust manifold. No room behind the engine.

So, ceej, I looked at your profile, and your a 2.2 LAP without SAI, correct? If so, then there is hope...

 

Yeah I do not have SAI, which is why I'm confused. I do have a 2010 so maybe they changed that? I'd have to see it

 

Its an emissions option made for year 2006+ 2.2 cobalts/g5s built for California and New York, at minimum. Mine came from NY...

 

So did mine

 

Did you get yours new? If so, its possible it didn't have SAI to begin with... I think I said it wrong, SAI is for all 2.2s built for California and some NY, at minimum.

 

No I got it used. It was at a rental place before so I would assume they would choose that as an option, but who knows.

I have the badmab header on my car, and by the looks of the diagram it should cover, I just don't know how that will effect the airflow. Are there any sensors hooked up to it?

 

Here's a pic of the SAI behind the engine, with the main unit w sensor wiring to the left and the tubing going to the right, just behind the plastic cover. Also, the plumbing goes all the way around the engine, and connects to the top of the air box.

 

Wow wtf. I mean if it covers it, you get a CAI, and you can delete the code it will throw it should be fine...might want to make a post in the l61 forum where there are probably more people who have dealt with this

 

Theres already a ton of info there already for that

 

I read here at css that the 2.2 LAP and 2.2 L61 have different heads, and thats why im trying to figure out what i need to do, if anything...

heres the thread that discusses it, at the end: https://www.cobaltss.net/forums/2-2l...ng-sai-191494/ He kept the SAI, i need to get rid of it with my badmab!

 

on my LAP i used the gm header honed header and i custom fabbed it so SAI still worked. basically the SAI arent on the header like old style SAI. there is this seperate piece. i have all the pics on my phone. im too lazy to upload them so pm if you want me send them to you. ill text em too you

 

So you kept your SAI, I wanna get rid of it! I don't wanna cut into this:

 

you should be fine. the flange should cover the two SAI ports. i wouldnt use the gaskets the came with it. let me know if it works cuz if i plan to boost in future i will wanna know

 

you recommend not using the new gaskets that came with the badmab?

 

nope its a crappy cheap gasket. i wouldnt use either one that comes with it. especially since youll be covering those two SAI ports get a good gasket

 

Would new stock gaskets work?

 

Got your note. I can tell you that the not only are the cylinder heads different on the LAP and L61, but that it is really the only difference. The rest of the block is pretty identical. The LAP switched from the L61's waste spark coil pack ignition to a traditional COP. They also changed the shape of the ports and put different cams in it. Unfortunately, I don't have any info on the SAI changes for that head. You can however find out by comparing pictures of the L61 head in my thread to anything you have of the LAP head. Should be able to find some picture on the net somewhere. The Ecotec line all share the same basic head geometry, meaning the port and bolts are all the same and any manifold will physically attach to any head. I just can't help you with the specific issue of the location of the SAI on that LAP head. Good luck.

 

Thank you. I'll try to dig up some pics...

I'm sorry, I didn't understand that line

 

hes saying the only difference on the LAP's is the Head, block design is the same. adn you have the 2.4 Intake Mani.

 

lol oh ok, cool, thanks!

 

It's a gasket. The badmab one is perfectly fine as long as it isn't bent during shipping
