You may want to check if you can see some oil residue somewhere on the turbo or any of the connections to it. It happened to me once where one of the fitting was slightly loose and there was just enough oil seeping to cause smoke. It got tightened up and solved the issue. Another potential issue I’ve seen is a case where too much crank case pressure causes the oil in the turbo to not drain properly and eventually leak through the turbo seals. With higher power levels, higher cc pressure can cause this, and cc ventilation can be somewhat tricky to achieve. Personally When my block was built, a regular pcv such as an sti one was not adequate and I had to move up to an adjustable pcv with dual AOS setup and closed ventilation to work things out. Good luck.
