Safe running power on standard internals

Safe running power on standard internals
Just a quick question really. Was wondering what power you could run a 2005 sti safely on standard internals, with the 2.0ltr top end and the 2.5ltr sti bottom end? Reason i ask is that i heard the 2.5 bottom end isn't as strong as the 2.0ltr? Thanks for taking the time to read this

I've been advised that approx 440bhp on a 05 STI 2.0ltr. Above 400lbft and the clutch will possibly be on borrowed time.
Don't know about the 2.5ltr.

400hp is pushing it on stock 2.5 internals. A set of pistons is all you need to push that to 450+.
