I have an '83 280 ZX. Recently while driving I hear this strange noise coming from underneath the car, well actually it's two distinct noises. When shifting or laying off of the gas from accelerating it sounds like well taking a penny and swirling it around in an empty jar, this sound can also be achieved in neutral, when accelerating I can hear a, well this sound is more like playing with the air nozzle at a gas station, I'm almost sure I don't have a turbo, well at least not standard, but I'd thought I give this a try. Also, when my car is cold I have tons of power, but after a slight warm-up (about a minute or two) I notice power loss, any answers to my questions are greatly appreciated.

You're not sure if your car has a turbo? There is your problem right there! Take it to a mechanic!
