GT3071R - Oil restrictor?
 

Hey guys, I'm coming to the end of my engine build and it'll be time to fire her up in the next couple of days. I just remembered reading about oil restrictors some time ago and realized I don't have one.

Do I need to run a restrictor with a gt3071r?

Relevant to my interests.

What I ran with GT2560/2871 and will run on GTX28...

-4 size Oil inlet fitting for GT28/30/35R with built-in restrictor : atpturbo.com

Garrett's spiel on it...

Oil & Water Lines | Turbobygarrett

the 2560 can be run without a restricted flow but you can use one to be safe.

negative. if it does not have one built in (never seen one built in), then you will have to run one external.

I thought garrett claimed that some of their bb turbos could be run without a restrictor. Of course you would run a higher risk of blowing the oil seals out of it.

Need an oil restrictor with all garett bb turbos.

Yes

Yes run restrictor. I have made the mistake of not running one in the past...

As did I, surprisingly enough nothing serious happened. Car started to smoke alittle, put the restrictor in, smoke went away, ran turbo for a year, sold it, still works fine (3 years later)
