No doubt, the 2.0 is limited in the cams and the fact it's a high RPM motor design without the ability to run high RPMs.

I wouldn't push a stock block much futher. Rods and pistons are both reaching redzone. consider cylinder pressures are ~25% higher than a 2.5L tune at any given WHP level. Then add on a factor for the EJ205 cams sucking at high power levels, and 320 WHP on a 2.0L is at cylinder pressures that the 2.5L sees at 400 WHP or more, which is definitely sketchy for the pistons. And rods have gone through blocks at <350 WHP.

Even given the issues the 2.0 has, 320ish WHP seems pretty low for that turbo. I'd agree that a compression test is in order.
