The tiny hole it is a restricts for the oil to run a ball bearing turbo The journal bearing turbo loves oil so if you running a journal bearing one drill the hole or just get another one and you can keep the restricted one for another turbo
@@AlonzoCubano There was no need to drill it out. The most common way to blow center seals is from oil stacking up in the return the second is sending to much oil to the center section You have about 80 psi of oil pressure by the time you hit mid rev range, there is plenty of oil going through that hole. I'd get another one anf go back
Unlike gasses, as flow volume increases pressure increases for a fixed orifice There is more oil in the center section of a ball bearing turbo at any given time. A thrust bearing center though has higher pressure There is no engineered volume difference need in the two center sections. The volume difference is just based on the physical space the balls take up making for more room. That decreases the pressure A ball bearing center spreads the oil through contact of the balls as they spin where as the thrust bearing does it through pressure to get the oil across the shaft and bearing A thrust bearing center is more LIKELY to blow a seal because the pressure is higher but both will blow seals if you increase the volume to the point where the oil pump is pressuring the seals because the oil can not get out of the center EASIER to do on thrust bearing because of volume but still possible to do on a ball bearing IF you increase the size of the hole with the same pressure They both use the same feeds They seal is a GAS seal to keep exhaust gas from passing through NOT a liquid seal to keep the oil in. Another thing that people forget is that the restriction is there because you added space to the SYSTEM by adding more volume. You created more volume to be filled with no increase in pressure at the source which means a pressure drop across the entire system The car was engineered from factory to have X pressure to get oil from the sump to the head and through the crank to the bearings THROUGH a filter You also change pressure dynamic because you have oil hopefully free falling into a crank that now sees PRESSURE under boost (why you should be running a catch can open to atmosphere from either the crank or the cam cover by rerouting PCV) In some builds you NEED to restrict the pressure at the feed to regain some of the pressure loses the system sees by having to flow extra distances into a crank case that is changing pressure with RPM I see a lot of people trying to outsmart Engineers and have made good money fixing those mistakes as an Engineer In a well engineered turbo the orifice is specific for the seal and is a best average for the differences in pressures across different cars In cheap cloned turbos its a general average to allow the turbo to function across different car's oil pressures Either way... don't increase the volume since turbos do not need much oil in the center. Do not increase the pressure there because the seals are not designed for that specifically @@TenthMan-ip2jp
@@jrich436 First of all journal bearing turbos don't have oil "seals" since what they use are more comparable to a piston ring and grove that blocks oil by slinging it with centrifugal force from the shaft. And lastly it's virtually impossible to pressurize the cartridge since it is connected straight to the oil pan through the oil drain line. The only limitation to how much oil it can handle would be the size of your oil drain, but with a proper size line it can handle as much pressure as the oil pump can put out since the cartridge is not really seeing any pressure, just volume.
thanks for this man. ngl the internet says and forums say the videos on how to do this are everywhere on the web and on youtube yet as i look there is no video thats comprehensive enough on this lmao. thanks for showing me! subbing
The threads to that union aren’t 1/8 npt they are a bpst thread pitch so it won’t thread in at all you can get a 1/8 bpst to 1/8 npt and you’ll be good to go
Thanks man! I’ve learned recently that if you have a ball bearing turbo, make sure to make sure either the turbo or that oil feed fitting hole is the required size and same if you have a journal style turbo. Ball bearing turbos want less oil in comparison to journal.
How dare you tell the makers of one the most reliable big power making engines that "The oil filter is in the wrong place, I don't see why they have it there" 🤣😏
I believe that information is more for ball bearing turbos. Journal turbos like a bit more oil than ball bearing ones which use a significant restrictor. In my case, it looks like I may have drilled the hole out just slightly too big as I’m using an an4 (which is recommended) and the restrictor itself was made for a ball bearing turbo. Time will tell and if there is smoke, I’ll just swap the fitting. Not really the end of the world.
@@AlonzoCubano no. they are right, you should not have drilled the hole If you smoke then the seals are blown and you need to repair the center section seals. They made TENS OF THOUSANDS of those feed plates over the last decade, been making them since the 90s. There is no way that yours was made off spec It was that size for a reason
@@AlonzoCubano I’m sayin this gon be a everyday thing? Need you to clean up that hole you drilled with the unibit Metal shavins all in the motor Rookie….

Thanks for that bit of information. I am running a journal turbo so I’m glad I drilled it out.
Thanks again.

@@jrich436As far as I know journal bearing turbos need a big volume of oil. What you said does apply to ball bearing turbos though.

A thrust bearing center is more LIKELY to blow a seal because the pressure is higher but both will blow seals if you increase the volume to the point where the oil pump is pressuring the seals because the oil can not get out of the center
EASIER to do on thrust bearing because of volume but still possible to do on a ball bearing IF you increase the size of the hole with the same pressure
They both use the same feeds

The car was engineered from factory to have X pressure to get oil from the sump to the head and through the crank to the bearings THROUGH a filter
You also change pressure dynamic because you have oil hopefully free falling into a crank that now sees PRESSURE under boost (why you should be running a catch can open to atmosphere from either the crank or the cam cover by rerouting PCV)
In some builds you NEED to restrict the pressure at the feed to regain some of the pressure loses the system sees by having to flow extra distances into a crank case that is changing pressure with RPM
I see a lot of people trying to outsmart Engineers and have made good money fixing those mistakes as an Engineer
In a well engineered turbo the orifice is specific for the seal and is a best average for the differences in pressures across different cars
In cheap cloned turbos its a general average to allow the turbo to function across different car's oil pressures
Either way... don't increase the volume since turbos do not need much oil in the center. Do not increase the pressure there because the seals are not designed for that specifically

Sweet motor man. I'm build a 2j ge vvti and needed a good way to feed and drain the turbo. Cheers

Hey man how did you fix your turbo drain clearence issue? I’m struggling to fit mine 😅
How did you end up routing the drain line? I have the same manifold and I’m in the process of figuring it out lok
I used a 90 towards the strut tower and curved the dash 10 into a straight that went into the pan.
What did you do about the turbo feed line size
How dare you tell the makers of one the most reliable big power making engines that "The oil filter is in the wrong place, I don't see why they have it there" 🤣😏

FYI it’s a bpst (what ever it’s called)type thread for you new guys. It was easier to tap npt for me as I’m using a 150psi sensor with 1/8 npt.

how long is that oil feed line?
Question what ecu and harness you use to make this setup work
Ecu emu black with a custom harness
That was small for a reason it keep oil in turbo longer but I would have make it bigger my self
Link to oil feed and line
lmfao the oil feed hole is suppose to be that small lmfao ... its so that your turbo doesnt get too much oil and start to smoke.
