Default How much boost can stock turbo handle?

I currently own a 2007 impreza WRX TR and i was just wondering about how much boost can my little stock turbo handle? I am shooting for around 300 HP was just wondering this just so I know if i should go ahead and upgrade or will I be alright with a stock turbo.

Thanks

You're asking a trick question. I'll give you this much, read the map notes from Cobb and they will say what they are running.

you'll get close to 300 crank hp with the stock td04. 300whp, not so much.

This question is impossible to answer. Call your tuner, tell him your goals, and take notes on what he tells you to do to accomplish said goals.
