DIY turbo high oil pressure regulator

I'm ready to boost my motor but the oil pressure is too high going into the turbo and causes the seals to leek into the exhaust and intake. So before I boost oil into the motor I needed to restrict the pressure with a way to moniter it so I don't fry the bearings. Common oil restrictors have no way to know if you are restricting too much oil. This simple set up is about $30 to build and allows you to tune your oil pressure. For any turbo its recommended to have 10 psi for every 1,000 rpms. I started out lowering my pressure from 40 to 20. I have since lowered it to 12 psi idle. for a good read on turbo oil pressure click on this link

Ball valves are not designed to regulate flow, they are only designed for full open or full closed. if you don't want that turbo to fail in the future you might want to pick up a throttling valve. just my .02
I have a vintage NSU with a semi automatic transmission. The torque converter is fed by engine oil and the pressure overwhelms the seals! I am going to use this great idea to keep the pressure to the converter reasonable.
I would check your turbos oil drain line. if it's to narrow it will cause your symptoms. You turbo has a built-in oil restrictor so it shouldn't matter what oil pressure you give it as long as it's above the minimum.
that is a short term solution you need something with a piston and spring and return. That will just limit the flow to your turbo. when at boost for a long time it will still ramp up pressure slowly. because oil pressure is constant. Depending on how much your turbo bleeds off. it MAY work but not really a permanent solution.
Good stuff man. Thank you very much
Just the solution i was looking for!!!!!Nice
Not necessarily. You can take the top bolt off the ball valve and then tighten the lower bolt so it is stiff, then put the top bolt back on so when you are driving the valve will stay in the same position.
@Carnifreekshow I did look into those restrictors that look like a carb jet but they had no way of knowing if you were restricting too much oil or not. I really wanted something adjustable with a gauge so I KNOW EXACTLY what the oil pressure is and peace of mind especially with a brand new $1300 turbo.
Should show the full throttle test as well.
please give us a followup. did it hold the same position, flow rate? Did the turbo like it by not blowing up?
can you tighten that ball valve to keep it from moving during high vibration? Was the valve still fine after the extreme oil temps?
I might do this for my dry sump setup.
ok now the question is, after its your turbo is warmed up, do you now open the valve to lets say 60psi the shut the hood and go driving?
Im going to put a turbo on my old truck. Im kinda new this turbo thing but can i use a oil pump and a oil regulator for the turbo? To use the right amount of oil to lubricate it? The way the turbo will fit in my truck is the oil feedline is at the bottom and exit is on top. My friend said something about fighting gravity? Think he refered to, oil wont go in the turbo?
Thanks
Yep
Did you ever have any problems with it after you had it on for a while?
Are you using oil restrictor on feedline on turbo? Or only this regulator? Because I have same problem and have restrictor with 1.5mm hole and it leaks.
Brilliant. I'll be doing this.
QUESTION???
Did your oil leakage stopped once you regulated the pressure?
after ur turbo leaked then you fixed the pressure problem? ur turbo stop leaked?
Apparently 40psi is recommended
Is 22 PSI high enough on full open throttle?
Did you ever look at the diameter off your oil drain ? That could of been one of your problems.
Pretty sweet set up bro!
Ya but those $6 oil restrictors are subjective to whatever the oil pressure is on any engine out there. Even the 420a's oil pressure differ from car to car. If my car idles at 60 psi and the restrictor only shaves off 20psi I'm still idleing too high for the turbo. My cousin tried a restrictor on his 5.0 mustang and went through 3 different ones to finally get the turbo to stop leaking. But suddenly his turbo fried cuz it restrcited too much. IMO a gauged set up is the only way to go.
Has vibrations from the engine opened or closed the valve from what it was originally set to?
also will the ball valve work its way shut or open from the pressure.
Brilliant and Cheap!
Good Job
wow, he should have paid attention in school
this is exactly what i had in my mind...never though other would actually make this lol
im only worried abit that the valve knob might turn abit...
Use a restricted fitting,
hi dear very good job, you are professional
This is what my turbo really need...thanks MAN.... have the same !@%% problem hey!!!!!!!!! first comment...make it cheaper and place it on Ebay-- :)
Nice
that is how you restrict oil flow not how to control oil pressure lol .. wow
Turbo's are not flow sensitive. They care more about pressure than they do flow, to a point. Everyone uses a restrictor to limit oil pressure in a turbo setup.
wpwwwwwwwwww
thanks
I wonder if can use it for a fuel pressure regulator
this guy is smart as hell im gonna try this
