Assuming completely stock, I wouldnt push it past 14-15 pounds.

that is IF the motor is in good condition and your fuel is sufficient.

15 psi is safer on a 2g than 1g due to the fact that we have more fuel pressure. I wouldn't go past 13 to be safe at least until you have the fuel to support it.

The change in fuel pressure between the two models is irrelevant. The resulting AFR is what matters, and they should both be the same. The 2g has a bigger fuel pump however, which is noteworthy.
The original question is somewhat vague. The motor itself can take 35 psi, or whatever boost it takes to make ~550 whp. The question was mostly likely more about what the setup as a whole can run for boost. Just a pet peeve of mine...

Ive heard of the stock injectors pushing 250whp with a 14b. I dont know much about that car though.

How much fuel/knock do you have because that is going to be your biggest hinderance.
And 14bs will run 12s with time and experience

I wouldnt push it too much, cars are different. I would get a logger if you dont already have one and just log it and see how your doing.
