Names Stewart I'm from Scotland in the UK

I drive a vauxhall VXR (i know its not a Chevy) but I am of the understanding I share the same 2.8ltr turbo engine as some models of Chevy? I am also of the understanding that some of you guys are running some serious power from this engine?

Which brings me to the reason I am here, I would like to know what models share this engine, also what steps you guys are taking to tune to such high levels,

Any help in pointing me in the right direction would be greatly appreciated,

Regards

Stewart
