If you emulate the inner diameter of the stock oil feed you should just about get it right... I believe its close to AN4.. but thats a guess on my part.

Bob,
Not a turbo guy but recall seeing in past posts that the full 75 lb + oil
pressure of the 13B could push oil past seal into the turbine housing.......
Not sure of the pressure recommended but I believe it was about 30 psi
after the restriction........This info is in the Flyrotary archive somewhere !!

Need a little help from you turbo guys.
How big should the restrictor hole be in the turbo oil feed line? 1/4 inch line from the oil galley to the turbo, on a 20B if that
makes any difference.
Thanks.
