If i was to upgrade my internals on my evo motor would i be able to run 30+ psi on 93

While technically it's correct, i'm sure you understand what people talk about in this thread.
When one talks about "running 30psi", one implies the highest boost a turbo will produce.
For a stocker it's around peak VE, 4000 rpms and then a quick fall off to 22 or so psi.
For a big frame turbo it'll come later in the rpm and stay till redline, producing big torque and big power with higher rpms, putting a lot of stress on the motor.
Stocker's torque will fall off pretty quickly.
So maybe you can see how 30psi does not equal 30psi. And running it on a stocker does not necessarily warrant any internal upgrades. It all depends on how much power/tq is being made. Not psi.
This OP question goes along the stupidity of another popular question - "Will i need to replace studs if i run high boost?"
And by the way crcain wasn't "100% wrong" as you put it - less backpressure from a bigger, slower rotating turbo wheel is what allows a big turbo be efficient and not suffocate at higher rpms.

please tell me I'm wrong and that 30psi on a 35R is different than 30psi on a 16g. Please tell me the pressures are different. Please, I dare you. Go eat a bag of dicks you douche nozzle.

You are being sarcastic right?
When people say "30 psi is 30 psi", generally what is meant by this statement is a question on whether there is or is not a difference in flow between the equal measures of resistance.
A lot of people, including myself, at one time wondered, if you have the same pressure, going through the same IC piping and intake manifold etc.. then can there be different mass air flows through this system? The answer is a big YES.

Do you actually think we are saying 30 pounds per square inch of resistance is not 30 pounds per square inch of resistance? I didn't think so.

im certain the stock engine can take 30psi with a stock turbo but if you start to knock. The knock pressure developed will decrease the life of your engine. or blow it. knock pressure is not linear with normal pressure. i.e if you run 22psi and knock pressure causes it to go to 66psi, if you run 30psi knock pressure will not be 90spi it could be more like 125psi.

Idiots like you are making EvoM go down the ****ing drain. Shut your ****ing cockholster until you know what the hell you're talking about.
