Oil Restrictor

Do you guys are running one? I know that every BB turbo should have one.

I'm seeing too much oil in my 300zx t25 turbo, but I think that my return line is too small. Brand new turbo and smoking.

all turbos should have a restrictor with either -3 or -4 feed lines and -10 or -12 return lines.

Cincy's spot on. Most of our oil feed lines are -3AN and the return lines are 5/8" which is roughly -12AN, I think. Mitsubishi turbos do not require a restrictor. Only ball bearing turbos need them.
