that's why I said Id have to research the engine to see if it could be modded. Even a newly rebuilt stock engine can have better mpg, not necessarily more HP but still better than an old tired block.

 

The 2.2 and 2.4 use the same block different cylinder sleeves.

this forged block has some interesting tid bits like the rods and pistons

I ran into a guy who told me about a 2.4 he built for his Equinox. Rods, pistons, cams, turbo, intercooler, more. Says well into 400 WHP. BS or not, sounds like fun.

In the early 70’s I had a 1969 Delta 88 convertible w/ 455. Maroon red and white vinyl. Couldn’t really afford to do anything with it back then. Oh what could have been.

 

Blue- I don't think so.......... The LE5 is larger 2.4 L—2,384 cc (145.5 cu in)—than the version of the 2.2 L Ecotec. From the bigger 88 mm (3.5 in) bore, and the 98 mm (3.9 in) stroke is larger, (aka Stroker) and VVT on the intake and exhaust improve low-end torque. Compression is 10.4:1. Power is 164–177 hp (123–132 kW) and torque is 159–170 lb·ft (215–230 N·m). The engine uses a reinforced "Gen II" block. Connecting Rods are GKN Forged C70 Powered Metal from July 2007 on.

I hear ya on that one. I have several I think back on myself.

 

Same block , possibly same sleeves, yes different heads and pistons and rods, but same block casting.

 

Blue- I still disagree. The 2.4 is beefed up in all the important places. I have this on paper from GM from long ago.

He's a clip:
OK in a printed page from GM & to ChevyMgr back in 8/28/2009. Topic: 2008 Ecotec 2.4L I4 VVT (LE5)

Quote: Displacement in the Ecotec 2.4L was increased to 2,384 CC, by increasing Bore & Stroke. to 88mm & 98mm, respectively compared to 86mm and 94.6mm in the Ecotec 2.2L.
The 2.4L VVT introduced a GEN II engine block that strengthened the block bulkheads to improve both durability & vibration control, w/out significantly increasing mass.

The 2.4L VVT uses forged C70 steel connecting rods that are shorter than those in the 2.2L, with a "Stroked" cast nodular iron crankshaft".

The 2.4L increases Horse Power at least 20% compared to all 2.2L applications, yet is only 13.2 pounds heavier than the 2.2L (which is the lightest four cylinder GM has produced, & one of the most compact anywhere.).

 

The stroke is in the crankshaft and or connecting rods, the bore is in the cylinder sleeves, the Gen I and II and III blocks are used for all three of the displacement’s , internal parts are different, the block is the same.

You do realize that wikipedia are only peoples opinions.. I laid out info from GM, I think I'll stick to that.

 

Factory GM Racing ran tests on 2.2 Ecotec engines adding nitrous and ran reliably at 250hp. At 283 hp it blew all the rods.
With new rods and pistons, the 2.2 produced produced up to 375hp.

With a turbo setup, better intake and exhausts and beefier crank and studs they got up to 500hp.
They went higher with crazy mods, over 700hp.

 

Where can I find that info ? Thanks
