What oil feed setup are you using, and how is it working out?

[asshanson]

I feed my journal bearing turbo off the filter housing, no balance shafts, no porting of the relief valve. I do have the red FP inline -4an filter with the .1 orifice meant for journal bearing turbos, but I only have like 5k miles on it so far. FP told me to check the filter element every 2 or 3 oil changes, I planned on checking it in the next 1k miles. I ordered a few extra filter elements but lost them, luckily they are cheap.

Oh, mine is water cooled as well. And I have no engine oil cooler.

Thanks, I can rest assured knowing someone has a similar oil feed setup as I want, and it works fine! Got one more question, where is the FP inline filter located, near the OFH or the turbo? Does your turbo use a banjo bolt for the turbo inlet?

Doesn't really matter where you put it I guess, I have a T off my filter housing for my pressure gauge and feed line, I have a npt to -4an adapter and hook the filter right on there. Then the line goes into the banjo bolt on the turbo.

If you have a fitting that goes straight down into the turbo you couldn't fit the filter pointing straight up, but I found that the banjo bolt 90* outlet was too close to the turbo and I couldn't even screw the inline filter on, so I had no choice but to place it down at the filter housing.

Not to be a jerk or anything but it seems so many people are worried about there oil pressure to there turbo, but nobody takes the time and measures there oil pressure to there turbo!

Actually, I'll be doing this. Im going to but a second oil pressure gauge on my durbo feed line, after my restrictor. Im planning on making a AN fitting that has a changable restrictor (small engine jet or somthing similar) so I can fine tune the oil pressure.

The math says that to reduce pressure by 50 percent, you reduce the total area by 50 percent in the restrictor. So after the restrictor, when the line goes back to normal size, the pressure will be reduced.

The gauge is probably overkill, but should be a good learning expierience.
