the question is how hard do you need/can rev these engines?
i have plans for bigger turbo, injectors and fuel system.
 
my motor is not a hardcore build by any means, but even with a decent aftermarket valvetrain, I don't spin mine over 6000 RPMs. I don't see the need to spin them up so high when these motors make a ton of power under 5000 RPM's if the turbo/cam/heads are matched very well.
