Hey best of luck, and if you have the cash you might as well get some head work done to make better use of the extra air. That would probably give some excellent results, oh yeah and a crap load of juice would be great too 
. If the ecu could handle it you would probably have the fastet hhr until the SS comes out.

No juice... we're using a AEM FI/C and a Saab turbo setup. If everything goes right I can get my 2.2 faster than the 2.0T when its finally seen on the streets. At least we're hoping anyway.
Did someone say JUICE?......:twothumbs

New manifold should be in my hands by Thurs or Fri this week. I have the perfect comparison car in mind.. (my friend Juan's Cobalt 2.2 5spd...) Our cars are nearly door to door when running from 40-90mph. When the manifold goes on my car this weekend we will run again and see if I can edge him out or lose horribly. Then hopefully this will either confirm or disspell any naysayers to the GM HO Manifold for the 2.2 ECOtec.
( here's to hoping!

Ok. So the new manifold has been on almost a week. First impressions are interesting. Below 3500rpm it feels as though the power has been bumped up a little and feels a little more peppy around town in daily driving below 3500.
When I get on it and take her all the way to redline its a different story. So in first if I just ease into it like leaving a light and get into more as the revs build the power flattens around 3500-4000 then starts pulling again and instead of power falling off at 6000 she pulls strong all the way to 6500 redline. Grab second and she just keeps pulling with plenty of power to "scratch" or "chirp" the tires going into 2nd a lot longer than before. And with heavy 20's thats an achievement! Third is the same and has a hint of torque steer when getting 3rd with a nice clean shift! Amazing results from the "butt" dyno so far. But that could be the much debated "vendor brainwashing."
We will be getting the comparison video this weekend to show the power difference. Already did a baseline run with a 2.2 Cobalt 5spd. From 40-100mph we are dead even. So this ought to be interesting with the manifold on. I will post the video results when I get them uploaded. Hopefully this weekend!

Yeah. The install on this was very easy too. You guys have alot more room.
But once we figured out what was needed for the swap, easy job. But we'll have to wait till next weekend for the "comparision". We going to a car show in Pinetopp's and Juan is going with.
But the more I look at the dyno sheets, the more I notice you only loose power from 3500-4500. You gain every where else. It not a bad mod at all. Cheap too.
