How much boost can i run in a stock 1jz?

Recommended Posts

I have a bone stock 1jz swapped is300, all fuel systems are still stock too. Is it safe for me to run boost just below the boost cut? Im new to the jz scene and im not too familiar with what kind of psi these stock motors are capable of handling
