FC chassis & diff power limit

How much are you guys putting out horsepower wise before needing to have a roll cage/stitch weld or replace the diff?

What hp would a good reliable daily driven street FC make? 300hp @ fly?

that would be suffiecent only if you had a gently used TII without many miles, the bracket on the rear sub frame that holds the differntial mount busted but my car had 100+k on the body and I'm only pushing around 250-260 at the flywheel........

The reason I'm asking is that, I'm looking at buying an FC most of which seem to have around 100,000 miles on them.

I guess a rebuild would be in order.

There is a 3rd gen giant turbo 20B in Middleburg FL thats Dyno'd >600RWHP with the stock diff.
I heard he pulled 815RWHP last month, but I haven't confirmed it.
