560whp is a little more than 322. So because he made that number on a 16g(with a different car), you are assuming he can make 240 more hp with a bigger turbo that you know nothing about? Anyone can make those kind of numbers on a 16g (with a 2.0l). It obviously gets a tad a harder as you start climbing up the HP ladder. The 3037s turbo from HKS isn't going to make a number like that without spray. HKS rates the maximum output of the turbo at 480hp. There are plenty of other choices to net that output but that turbo isn't going to do it.
