restrictor, hopefully last question

Would this work for the head as well as the turbo? Or could the hole for the one in the turbo be opened up for more flow into the turbo?

Thanks to Chris from TU for the link, BTW

And if the .035 is to small too feed both here's another:

No matter what you try you will need to verify hot idle oil pressure
at the head with a gauge. Try the .035, just open it up if the psi
is too low at idle when hot with a drill bit.

I run a .098 restrictor into the head...no problems so far (i also have 2 -12 drains).

does the .035 really need to be in the turbo? Thats 1 bearing i wouldnt think could get TOO much oil, no?

[nemesismachine]

Ok. So I can run a line straight from the block, no restrictor on the motor. And run a seperate restrictor on the head AND on the turbo. Sound right?

Why would you want to decrease the amout of oil to the turbo bearings? Or am i missing something?

supposedly it needs to be regulated as well, to sustain oil pressure across the board.

correct me if I'm wrong but doesnt the oil feed to the turbo come from the splitter in front of the block, the oil restriction happens in the head when the oil is pushed up the block from the oil pump.

basically if the preasure is too high it can blow oil out the seals

Yes, I agree with this comment, am I wrong? The restrictor in the coupler on the front of the block should be enough, no?

Only so much oil can actually go through the bearings. just because you are pushing more oil at it doesnt mean you are going to actually move more oil through the turbo.

The restrictor allows you to be able to have a hole big enough that you are getting enough oil to the center section but not allowing the oil pump to just slam the seals in the turbo with excess pressure that cant get out.

[nemesismachine]

but you see, thats my issue. I dont have the restrictor thats supposed to go on the front of the block. Back to my initial problem, WITHOUT the restrictor on the block, will the restrictor on the turbo and on the head suffice?

[phantomrt]

Hmmm. My turbo cars have no "restrictor" for the oil supply to the turbo. The feed line comes off of that "oil distribution bloc"k in the front of the engine, straight to a fitting at the turbo with no small orfices for it to go through.

I don't see how this oil distribution block thing I refer to can be considered a restriction. The hole is big. So is the hole in all the fittings that go to the turbo. Where's Chris W?

That is true on the 8v head. He is asking about for the 16v head where you have to run an external oil feed line and it needs to be pressure regulated so you don't starve the engine for oil.
