How GM developed our stage II engine block

"The new turbo Ecotec was defiantly responsive: GM Racing set idle at 1800 rpm, and if you punched it quick, the unloaded engine would blow completely through the 10K rev-limiter in less than a tenth of a second. "

Interesting article, if that is the forbearer of our 2.0 redline engines we do have room to grow. Did anyone notice the cold air intake?

If you read the article closely, they mention thickening the cylinder walls to handle more boost. It explains why the 2.0 has 2 mm less bore.
