All 2.4 are drive by wire with the stock ecu. I believe you can run a tb from a 2.2 and custom ecu but its going to run you 1k+.

don't unless you run some baby chains. When you have to defy gravity you will have to let off the gas to keep from flipping over backwards.

For the amount you spend on a 2.2, there really isn't a reason to bypass the 2.4L VVT motor. It really is superior in ever way. We chose the 2.4L in our off-road applications. The LE5 is a larger 2.4 L—2,384 cc (145.5 cu in)—version of the Ecotec. Both the 88 mm (3.5 in) bore and 98 mm (3.9 in) stroke are larger, and Variable Valve Timing [VVT] on the intake and exhaust improve low-end torque. Compression is 10.4:1. Other reasons include:

* The cost difference between the 2.2L L61 is negligible.
* The 2.4L LE5 offers more displacement
* The 2.4L LE5 supports VVT
* The 2.4L LE5 supports Electronic Throttle Body
* The 2.4L LE5 uses the 'reinforced' GM GEN II block [the same block as the LSJ/LNF]
* The early production [2006-2007] 2.4L LE5's are BOOST READY w/ forged pistons, rods, & crankshafts
* The 2.4L LE5 has targeted oil jets to cool pistons
* The 2.4L LE5 has a higher flowing intake manifold [than the L61]
* The 2.4L LE5 uses 58X crankshaft position sensing
* The 2.4L LE5 uses digital crankshaft & camshaft position sensors
* The 2.4L LE5 uses an individual coil on plug ignition system
* The 2.4L LE5 uses the vastly superior 32-bit E67 ECM

Just something to think about! The 2.2 L61 is a good motor, don't get me wrong! If you need harness or ECM tuning support let me know.

Other than the no replacement for displacement thing most of this list holds true for 07 and up L61.

I agree with you on most of similarities I've listed, however, the L61 was re-dubbed LAP for late 2008. When I see folks going 2.2 they are usually the early version L61. Just some food for thought.

The only thing I miss is the Cavalier power steering pump driven off the camshaft because it would sure make it easier to put the power steering on.
