Here is the shitty part about this whole conversation,
since we are ultimately applying this to the D4-S 2.0 flat-4, which would most likely have a compression ratio ranging anywhere from 12-13.5. This is not because the internal chambers produce that much compression, but due to the fact that the direct injectors themselves inject fuel DURING compression stroke, after port fuel has been injected via, intake stroke.

Here we add boost, no matter how much timing you pull we might be reaching the limits of how much pressure each cylinder can handle even under small boost. There are a few other variables im not to sure of as well...

Are you saying you think the frs/brz will have that high of compression?
