That may not be good for turbo oil outlet, which is not pressurised. Both sides of oil-filter has pressure, the inlet and outlet. This will prevent turbo from draining oil through. Best to tap return port into oil pan above oil level to give zero-pressure area to drain oil. ID of drain tube should be at least 14mm
Also turbo oil-feed is very low-pressure, low-volume. Should use an inline filter with 3mm restrictor. Too much oil pressure and volume at turbo inlet will cause oil leaks to outside of turbo and into intake.
