Default Precision turbocharger Oil restrictor?

Hi, i have to build a turbo kit for a s2000, never used precision turbocharger really, everything garrett , and i was wondering if these turbochargers require oil restrictors too, turbocharger is 6266.

Thanks!

.065 restrictor just like journal bearing Garrett turbos, or .035 for ball bearing turbos.

The need for a restrictor is entirely based on the maximum oil pressure the engine produces.

that being said basically every Honda requires a restrictor due to the high oil pressure they produce.

All precision and Garrett turbos need a .065 restrictor for non ball bearing turbos and a .035 restrictor for ball bearing turbos on a honda engine.
