Anyone running an oil restrictor on a -3AN oil feed line?
Set up: SC 61 turbo/B18c.
Im replacing my -4AN line with a -3AN line due to oil consumption (oil being pushing passed the turbo seals). Will the -3AN be enough oil restriction alone or should I add the oil restrictor on top of that? The oil restrictor I have is a #72 or #74 NOS jet (I forget which one).

I welded my 90 degree nipple on the turbo shut and drilled a small hole through the weld to act as my restrictor.. I forgot what size drill i used, but it's been working great so far.. btw, i'm using a 4AN line ..
I never see any smoke comin out the exhaust, or oil residue in my turbo inlet and turbine outlet...
a must, if you have MINOR oil seal problems...

I had never seen any factory turbo'd engines' oiling systems until a couple nights ago working on a friend's SR20DET. The restrictor is placed in the banjo bolt and the oil feed hard line is probably equivalent to a -4AN line.
We've also had problems on a 3G Eclipse turbo setup when it didn't use a restrictor. It used a -4AN line.
It doesn't help the original poster, but at least it'll throw more info into the general knowledge pool.
