I heard it can handle 8psi max when stock. I wouldn't do more than 6, that seems like the magic number to keep it within the stock mettalurgy

Even at 8psi a stock 1NZ-FE is on borrowed time. Weak spot is the rods, they're just super thin.

Toyota sold a factory turbo 1NZ-FE overseas in a handful of cars and they were rated at about 150hp to the flywheel. Thats about as much as I would go without opening up a 1NZ IMO.
