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

sleepydsm · 01-18-2009

Hey, just contemplating where to feed my journal bearing oil only turbo from, and whether I should be using a restrictor and or filter on my mostly stock engine that DOES NOT have balance shafts. The oil filter housing thing has not been ported either. Lets hear about what you're using for your oil feeds!

I have a BB turbo but am running it off of the oil filter housing with a restrictor. I did this mainly because the oil is fresh out of the cooler and the filter.

most usually feel bearing turbos from the banjo bolt on the side of the head, and journal bearings off the filter housing.

My setup shouldn't be all that different then yours. MY BS are removed. I run a journal bearing BW. Mine is fed from the filter housing. My oil inlet flange on my turbo was straight from Bullseye who I got my turbo from. The hole in it is tiny as to act like a restrictor. That's what they recommended, and they are the ones I ordered the turbo from, so I took their word for it.

So yes, mine has a "restrictor" (a tiny hole).

I wonder if I should add an air to air oil cooler for my turbo's benefit. I still have the coolant cooled oil cooler housing, and I like the idea of eliminated those stupid little coolant lines behind the turbo, And I'll be needing a different water pipe anyways...

I was thinking about the FP inline filter/restrictor (.100" orifice) from the OFH for my setup. Opinions?

I went to the external setup also. In the end didn't cost me all that much. Just used some cheap push-lock fittings/hose from Jegs, and a Long cooler. Pretty easy.

As for the feedline, that setup sounds good to me. Just make sure you clean that filter out on occasion so it doesn't become clogged and starve the turbo.

I feed mine straight off the filter housing, no BS and journal bearing PTE. I fed both of my PTE's like that and never had a problem. No restrictor or filter and I was using the stock cooler for the 50 trim, then no cooler at all for the SCM61.

See I keep hearing all this stuff, "it will blow yhour seals!" "It won't do anything!" Etc. I almost am afraid, what if a restrictor or filter actually causes too low of volume and pressure, and I'm effing it up. I plan on checking that tiny filter like once every day when i first install it then once a week then every oil change lol.

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?

I use a BB turbo fed from the oil filter housing with the black FP inline filter/restrictor. (I don't remember off hand what size the oriface is) I have an external oil cooler from a '90, and I don't have any problems with it. I usually check and clean the fliter with some brake cleaner every time I change the oil, and I've got it set up so the feed line comes off the filter housing, into the restrictor, then straight into the turbo.

**Shane@DBPerformance** · 01-19-2009

I run no BS and the oil feed off the head with a Garrett center section turbo. My last turbo lasted a long time like this and this one has been on for a while with no oil in the intake or exhaust side. If it had BS, I would goto the oil filter. If you don't have BS and your running it from the oil filter, then I would higly recommend the FP filter setup or some kind of restrictor. I had problems on my 2G with it blowning turbo seals with no BS and no restictors with an oil filter feed.

Swifty1638 · 01-19-2009

so i should get this then for my turbo..

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!

**asshanson** · 01-19-2009

My gauge is right in the line that feeds my turbo, I'd say it's close enough.

twack · 01-19-2009

I run my 50trim of the head , and have for years

turbotalon1g · 01-19-2009

This is an awesome question and one that troubles me a lot.
I ran my scm61 off the filter housing with BS and blew the seals, off the head without BS and it was fine.
I might try to measure pressure at the turbo and make my own restrictor.
If this is for your holset, then I might go with the black (.80 restrictor I believe).
The guy that made his own, used a .78 jet. Holsets don't like anything over 70psi i believe.

sleepydsm · 01-20-2009

Maybe pressure at the head( w/o balance shafts) is high enough to be within Holset specs; I'll just get the FP filter/.100" restrictor and use the OFH.

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.
