Look,
Im not tryin to get into a "lets see whos doink" is bigger. Ive never heard of puttin in a oil restrictor to fix a leak in a turbo. Consider its spinnin in excess of 30,000 rpm, id want oil to the bearing in a major way.
Big truck turbos run 25+lbs boost all day long, whats the diff ?
If Garret said so then id like to see it.
