How much boost pressure can stock 1g internals handle?

[KCz Eclipse]

I have a 1991 eclipse gsx. It is currently stock with the exception of a 16g and fmic. Very soon i am getting a fp manifold, hard piping the intake, cant think of anything else off the top of my head. Am open to recommendations. Back to the point, how much psi will the internals handle. Not to mention injectors and other things. Im currently running 7 to 8 psi, which is very weak, and was looking to bump it to ATLEAST 12+. What do you guys think.

Thanks

You can't really use "PSI" to gauge when it will max stock injector IDC

Airflow, pump, pump voltage, fuel lines, and AFR are going to be what determines that.

I have a thread here somewhere from when I maxed out my 450s on the 14B with around 35lbs/min airflow, which is certainly not typical for the 450s (or a 14B for that matter)
