Ok...so after the opinion festival has ended, we're left with this....the benefits/consequences of Nitrous vs. the benefits/consequences of Turbo. Keep in mind in life there are other means of producing power and boost as well i.e. superchargers, methane inject etc.... so just figure out what best fits into your lifestyle and what you're trying to accomplish. Stop trying to turn personal prefrence into hard facts because if you get beat by a car with nitrous or turbo...no one is gonna wanna hear your " he cheated" excuse.

The pistons do not know -nor do they care- where the cold, dense air/fuel mixture is coming from. All they know is more air/fuel and more power.

On the butt-o-meter, a properly set up nitrous car will pull car lengths off the line against an identical car with a turbocharger. Nitrous makes torque (even though the kits/jets are rated in horsepower) and lots of it. Stump-pulling torque.

Unless you ramp up the nitrous flow with a progressive controller, the torque diminishes at higher RPM. Which is where Mr. Turbo comes on strong.

A 70-ish direct port shot put me right at 13.70s @ 99-100mph all day long. Never broke one tiny, single thing on the engine.

T28 setup at 11psi and 4-bar fuel pressure put me at 12.80 @ 110mph all day long. The ring lands ended up disintegrating after a couple years of this abuse.

Both nitrous and turbo are fun. Fun is why we mod cars. I can build a nitrous car that will outrun a turbo car, and vice versa. The end result is the end result and it does not matter how you arrived at that result.

To me there both the same. The only advantage a turbo has over nitrous is that you can race on a course and hit turns smoothly during boost. I don't think hitting the switch while in a turn is a good idea.

During drag racing the only difference I could imagine would be that a turbo would have a delay until full boost and N2O would probably make traction a bigger problem when you hit the button depending on what shot your running or if your running a progressive controller or not.

Of course if you have a some type of pro drag machine all of this would of been thought about before hand and may not apply, but for the occasional racer, or enthusiast, I'm pretty sure this would apply.
Just my 2 cents.
