I know that our internals are better than the 2.2Ls but how much hp and tq can we get out of the stock bottom end? The 2.2Ls rods snap at 287hp and the crank is good until about 500hp so if we have better internals when are our rods going to snap? I'm also wondering if anybdy like Psi-fi has blown a motor up yet to find out how much power we cannt add. Below are the GM testing chart for the 2.2L (they put n2o in it till it was inefficent then they turbocharged it) and then what gm says about our bottom end.

ROBUST PISTON AND ROD ASSEMBLY
The Ecotec 2.0L SC engine is designed from the inside out to handle the demands of a 200-horsepower supercharged engine. A 5.6-mm piston top ring land is utilized for piston strength, allowing optimization of engine performance. The pistons themselves are cooled and lubricated by targeted oil jets that keep their underside, along with the cylinder wall, in a continuous oil bath. The large 23-mm piston pin provides a larger bearing surface to better handle the increased loads of a supercharged engine. The connecting rods have been upgraded, incorporating a larger forged I-beam section for added strength.
ROBUST DROP FORGED STEEL CRANKSHAFT
Like the upper end of the engine, the lower end of the Ecotec 2.0L SC engine is also built to provide lasting performance and durability. The crankshaft is a drop forged steel design that incorporates induction heat-treated fillets for added strength, and cross-drilled, chamfered oil passages for excellent lubrication characteristics
