Poor engine performance, white smoke.....

[95tsiAWD]

My car had a 14B intially when the problems started happening. And it ran fine a year before the problem a month ago. I got the 16G cause I wanted one, and because I thought maybe a blew the turbo. The smoke is probably from the oil and anitfreeze that spilled out during the turbo swap and its just residue. The question still remains ........ what the f$ck is wrong with my car 1995 TSi AWD, auto
