I would like to know what size restrictor to use and what downpipe flange I would need so I can get the exhaust shop to make me a custom downpipe. Let me know if you need more pictures or information.

 

Do you know the a/r sizes of the compressor side and exhaust side. If the turbo isnt ball bearing there really is no use for a restrictor, and you will need a 5 bold exhaust flange. Hope that helps you out.

 

I had the same question regarding my Garrett .57trim and posted this thread not too long ago>>>>

As you'll notice, there are ALOT of different, good opinions from some people on HT that know there stuff. I run a .065 restrict-or flange on my btw... GOOD LUCK!!!

 

Run a restrictor. You will need one. Turbos only need around 10 psi of oil press. Now think if you ran 70+ lbs of psi what it would do? It will push past your oil contole rings and it will then smoke.

 

that looks like the larger ford style 5 bolt dp pattern.

 

The exhaust is a .48a/r and the intake is a .42a/r.
Well I decided to use a .060 restrictor, now I am just trying to find a downpipe flange. The normal t3 five bolt flange just doesn't line up.
