2.2L Vs. 2.4L
I've always wondered. What are the big differences between the 2.2L and the 2.4L besides displacement. Are the 2.4L internals stronger? Details please

the L61 uses a 10.0:1 compression ratio and is obviously .2 liters smaller. The LE5 has more displacement, uses a 10.4:1 compression ratio, and has a VVT head. Thats really it. I think the 2.4 uses either stronger pistons or stronger rods, but not both. I can't remember which tho.

The nitty gritty of it is not only the VVT and displacement but the longer stroke adding additional crank leverage for peak torque at a faster engine speed.
Along with VVT, the 2.4L also has slightly more aggressive cams, higher compression and a more aggressive timing map.
Engine management is vastly different.
GM is now listing somewhat conflicting information about the LE5 connecting rod limitations. LE5 internals were believed to be stronger as evident by GM's powertrain data on their website (forged connecting rods more specifically). However recently published GM Performance data indicates 2.4L connecting rod failure point as the same as the 2.2L which may indicate a misprint on the powertrain website.

Witt, you and your group (and they know who they are too) are just way too modest.
You guys have helped many of us far more than we would ever be able to repay! Well cept Area I can do what I can for him, and I know he's just one of the members of your brain trust!
I for one thank you!

Intake and exhaust manifolds are different - bigger/better flow capability on 2.4.
TB on 2.2 is 60MM
TB on 2.4 is 68MM
Freer flowing exhaust system on 2.4 -- DP/cat-back
2.2 Auto Tranny has 3.63 final drive
2.4 Auto Tranny has 3.91 final drive

Oh wow thanks you! I went back and re-read the GM spec sheet for the 2.4 and your right. The crank is cast nodular iron, its the rods that are forged steel.

Haha... no I was just clarifying before anyone else jumped in and took it the wrong way. Internet = overly sensitive.
