Turbohatch33

As title say my turbo K24 blows out blackish water on cold start an I wanna know why. I'm new to the turbo seen so its got me stumped. I've looked all over the internet reading for about a month an have gotten no where. Car runs like a dream an has lots of power. I'm just worried its oil is coming through the turbo an mixing with condensation. If so how can I fix it. The car does not have a full exhaust. It has about 3.5ft of exhaust off the turbo. Any help would be appreciated. No smart *** comments please. Thanks.

Black soot will result from rich A/F ratio..
Water is 100% the result of normal condensation of hot humid exhaust gases hitting cold exhaust pipes.

Thanks Slumbertcivic. So I need to lean it out some to make it stop? It's a/f gauge reads 10.0 when get into it and 13-14 when I'm cruising at 60mph but idles at 16+

I haven't had the car very long and still figuring it out. I plan on having it tuned soon since idk what the tune was when I bought it. With those number will it hurt it any or am I good to drive it till I get it tuned?

It's just water coming out of the exhaust. Totally normal.
There's always soot in the exhaust, also totally normal.

You say the car runs great, DO NOT lean it out or change anything.
If it's at 10:1 under max load....... is it supposed to be running E-85?
I'd expect 12-12.5:1 for NA on straight gasoline, but I'm not used to seeing numbers for a turbo application.

I believe for turbo application you run richer as boost increases to keep cylinder temps down. Depending on boost amount it might need to be that rich. I wouldn’t go leaning things out, thats dangerous. Take it to a tuner and see what they say.
