I was wondering if anybody had any info on restrictor size for a ball bearing turbo? Even for a thrust bearing turbo too. I think I read somewhere .060" for non bb and .035" for bb. I have a -4an to .035" restrictor from ATP and wanted to make sure it would work ok. The hole seems very very tiny Don't want to starve the turbo Thanks.

that hole is fine, you won't starve the turbo, because it is at a constant pressure which is more important for BB applications. remember, the ball-bearings mean that it is floating on a thinner cushion of oil in its bearing system so it is not needed.


You're fine, don't overthink.
