from what i have read the 09 lap with vvt it is a pointless mod to put the 2.4 intake on since the 09 uses the 2.4 style intake. they arent exactly the same, but very close.
You are correct...the 2.2 LAP intake has larger runners then the 2.2 L61. Very similar to the 08 2.4 intake if not the same -- I'll have to look it up again. The plenum is smaller than the 2.4 though. The 06/07 2.4 intake is the largest of all the ecotech NA intake manifolds.
