Stock STS turbo
You can get away with 700hp on the stock block, but not for long. The best way to make the motor last with that much power is by easing into it (EVERY TIME), which is pointless. This is of course providing you are not experiencing any detonation.
You will want to build a forged motor (at least forged pistons and rods, but crank too if you can afford it).
Stock turbo will not do it, look at your other threads when you asked the same question. With nitrous, yes you can make 700hp with the stock turbo, but again, you can see how long your engine lasts or just do an engine buildup right away.
