Do you have a belly panel under your engine bay?
If not get one or get a filter on the turbo.
A turbo is sensitive to dust.
Even the fuel from a suck through system wares the blades completely over time.
What I do when I have no choice is use mesh and then silk stalking over it.
I rather lose 5hp and have a healthy clean engine with working rings and valve stem seals for 100000+km
