Look around, there's always somebody pushing a stock block to 1000 horsepower, the question is who. Usually a shop or someone with DEEP pockets playing this game. Anything over 600 is going to dramatically affect lon-term durability. Everything has to play together just nicely at that level. One bad tank of gas or a tiny shot of boost creep or similar can pop the party balloon, as you've consumed all the safety margin engineered in and more.
BTW, turbos are fantastically good at wrecking things if not very carefully tuned and set up.
