In a very general sense, turbos and nitrous both add more air and fuel to the engine. And both put a certain amount of stress on the internals that can be measured in psi w/ turbos. So we all seem to agree 8psi is safe for the 5s. But we've seen 12psi, forget who. So what would a 50 or 75 shot translater into as far as strees like psi? Meaning, wouldn't a 75 shot be like running 7psi? (round 9-11 hp per psi, 75 shot equals 75hp) I know my equations are creud, so if anyone can clear up, lemme know.

the problem with nitrous is that most people dont do the mods that are needed to support it.  you  stock ecu is going to flip out when it gets a 50hp shot out of nowhere.  you need bigger injectors, and some type of tuning.

turbos are a better idea, because it gives you power that u can feel in daily driving, not just in a single joy ride.

I bet my car had fun with its 75-shot. I can't do it anymore though because my clutch is gone. My friend was running a 100-shot on a stock 7a and it held up. He didn't want it too though they were gonna go 7age till that fell through.
