Technical Car won’t boost and white/blue smoke pours out after swapping turbos need help

[Oegan]

I recently blew the old 17t’s that came with my 135i when I bought it and bought replacements after installing everything (torqued to spec with all new hardware and seals minus new feed lines since they looked perfect) it was finally time to start the car. After cranking to get oil into the turbos and bleeding the cooling system I started the car and had some light smoke coming from the engine bay which I expected since I had accidentally spilled some coolant on the turbo side of the engine. Well I went to pull it out of my garage after idling for 5 minutes and more smoke started coming out of the exhaust. The car was on empty so I went to the gas station 2 minutes down the street and the car was fogging up the street behind me. On the way back I went maybe a quarter throttle maybe a bit more to see if it would boost and absolutely nothing. I have the car back on jack stands and there’s no leak or loose anything. It already has a dual catch can set up and so far there’s nothing in there.
