Random smoking?!

[ajolliff]

ALright so I have been driving around this week and noticed about once or twice, I will look behind me when I am driving at very low speeds, and soo a big cloud of smoke behind me. I guess the smoke if a grayish black color and is coming from underneath the car. You guys think that I might have a coolant leak or a blown turbo? I personaly don't think it is the turbo, just because it spools good and i get now pwer, and have hardly any blow by. I was just wondering what you guys thought? I am going to look and do some inspections on the car tomorrrow and see whats up. Just to let you know I have a 91 s13 with an freshly swapped sr20det with I/c, Sard R2D2, Walbro 255lph, 300zx Fuel filter, SAFC-II, and turbo back exhaust. Thanks a lot!

sounds like it might be the turbo starting to go out to me. take off one of ur charge pipes and see if there is ne oil or ne shavings in there. if not, you just might be running pig rich. if you figure ne thing out, keep us updated. GL.
