Default Restricter size for GT2860 rs

Gettin back into the miata project game and the turbo lines are pretty much situated and wondering what size oil feed inlet people use. Right now the regular -4 an fitting is 5/64ths (.1406) and for a BB turbo its too much. I the smallest drill bit i have is 1/16th (.0625). What should i use?

No idea. I think ATP sells something in the .060 range as well, not 100% sure. It's probably fine provided you don't have some crazy 70+psi shimmed oil pump.

too big. I have a .035 with #4 lines. It works and no more smoke at cold-start and now more oil through the BOV.
