They CAN go that high, but none of them will without throwing at LEAST as much money at them as the 2011 crate motor costs.

It all boils down to what everyone knows. Going fast NA costs money. I'm sure the availability will increase (and cost will decrease) as these cars get wrecked but at $5800 shipped - I still maintain that it's a bargain. I'll likely make 410-430 at the wheels which is damn sexy for that price + MPG + OEM Reliability.
