most guys get the gt67 upgrade i read alot about the stock turbo dumping at the top of the rpm range.as for your question i think it can make a little over 600 the 67 is good over 700.on a stock motor at 5psi you gonna be making about 415 maybe. hope this helps

GT67 is good for 750 chp, if you plan on 700rwhp you may want to consider a GT70, although the 67 should get you close ...but at 700rw will not be completely efficient.
