newb turbo question.

[Pimpin Dsmstyle]

Garrett T3/T4 57 trim. Im at work and am having a hard time finding some specs and comments on this turbo. I can pick it up ( nearly mint) with an Ex. waste gate and the flange off the mani for 600 obo. If i was content with 400 hp, will this turbo do it? I would like to not push the turbo to its limits. Any help would be useful. If you dont want to help guide me, please dont leave a comment.
