not all turbos even need a restrictor. restricting a turbo can harm it just as well as over oiling it. some setups are using -6 as an oil feed with no restrictior but also using -12 as drain.

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
Interesting. Not saying you're wrong, but in my experience the oil restrictor has always been needed. I figure that restricting oil flow too much will sieze the turbo while over-oiling it will just push oil past the seals but still allow the turbo to spin. Over-oiling has happened to me a few timesOriginally Posted by Quik
How big are the turbos with -6 feed and -12 drain? I'm assuming they're pretty big.

it all has to do with how much can escape really. more goes in the more has to escape at similar rate. being rear mount youre already fighting gravity, not mention on how far your oil has to travel to exit the system.Interesting.

i supply 65psi at idle on my current setup and last setup saw 55 at idle both pegging the guage at 4000+ rpms.
but if it works for you then so be it. just make sure your getting enough oil to the turbo or it will the bed early

Will do. Thanks for all the input

With your breather setup did you eliminate the factory pcv system all together (nothing to the intake manifold or before he throttle body) and just run the breathers to the catch can?

Yup, I deleted the factory PCV system and just ran hoses from the valve covers to the breather tank
