Holset Oil feed "pre-made kits and your experiences"

[turboglenn]

I've searched andfound many different routes and know how to build lines too but i was just wondering for those with a lot of miles on their holsets, that have had good life from them and no troubles with the oiling system currently being used.

But would you mind linking to the line you used, your engine setup as far as it's oil pressure/BSE?/OFH modded?? and the miles you've put on the turbo and your satisfaction with overall fit of the kit, and if you know it, what size hole in restrictor?

I don't have the option of the 12 x 1.5mm thread at the CHRA because my unit has the inverted flare fitting cast into it, so whatever i get i will have to adapt to a -6 atthe turbo which i can handle, but please link me to the kits you used

not a single "turbo trader" link has worked for me, seems to no longer exist

I run 1/4" swagelock hose and fittings off the filter side of the OFH, un restricted. My engine makes about 85psi when hot on the pre filter side. At the turbo inlet I have about 50-65psi at 4000- 8500RPM.

Personally, I am not scared of running 80+psi to my turbo, you absolutely will not "blow" the seals. At super high pressures you can actually burn the oil in the bearings, but thats way way way higher than 80psi.

A good drain is imperative however, you won't 'blow' the seals, but it will smoke. Mine smoked horribly when I had a cobbled drain, it even leaked out where the chra joins to the turbine housing, . Soon as I fixed it, it was all better.

Heres my setup

I'm digging that WGA setup you got there. Very creative.

As far as I can tell, most if the holset failures I see are due to not having a sufficient oil drain.

bastarddsm, your pics aren't working for me...

 

[turboglenn]

Pics aren't working here either, I came up with a complete feed tonight but still have one damn problem, no fitting at the turbo, since i have the flare cast in all i have is a -6 fitting that will seal to it, i could machine it off and thread the inside of it i guess or find some place to get fittings that takes paypal, I was on ANplumbing.com or whatver that nice site is and they had no paypal option after i spent 2+ hours on there picking out the parts for the perfect oil supply

You should get a Paypal debit card if you use Paypal a lot. It's free and makes it so you can use your Paypal balance to pay at places that don't take Paypal. Plus, you don't have to wait 3-4 days for the transfer to your bank account and you get 1% back for some purchases.

As far as the oil feed goes, I'll be running a -4an line off my OFH. I'll be using a nitrous jet on the end of a fitting in place of the flare and I'll drill it out as needed.

So it will be BSPT to -4an 90&#176; fitting, -4an female to -4an male with 1/8" NPT tap: -4an male end machined flat for the nitrous jet instead, then -4an line with female fittings on both ends. Then for my HE351ve, it's a M12x1.5 fitting, so I'll use a -4an male to M12x1.5 unrestricted banjo bolt.

yea,i need a paypal debit card, would really help a lot

as for making oiling pieces, i've done all that, i've got a few ways i can oil it, I was really looking for feedback on any kits companies offer, but i did enough machining tonight that it really don't matter i'll have what i need either way. was just looking for something that was "install and go" for once because i need to focus on working on other things. but like i said i took care of it tonight and came up with 2 more ways to oil it, i just need to check pressures and can't find my gauge fittings i had ina little baggy in my glove box

let me know what you drill it to and what your results arethough, i'm interested in hearing.. I want to make sure there's not enough oil to slow the spool but i want enough to have sufficient lubrication and figure i'll spend lots of time experimenting which was another reason i was looking for feedback on premade line kits or some one to say "i run no BS's, non ported OFH, and "X" restrictor for 10k+ miles and no problems" i'm asking for a lot

Lol You like that? Works like an absolute dream Rock solid 22psi from 4000-8500. Working on a billet two port actuator so I can use a paint regulator to adjust the boost up.

Anyway, The pics should show, just click on it and go thru the album.

Glenn, I see no reason why a 3/16" or 1/4" line off the ofh wouldn't be just fine. Just make sure you got the drain for it or it will smoke.

I WOULD NOT restrict it. Run it off the clean side of the filter which will be about 20 psi less than your gauge shows anyway. Put a gauge on it, make sure its at least 60, and not to much more than 80. Run a healthy drain and your set. I've got around 3k on mine HY so far and 2500 of it was at 22psi and 6-8000RPM, . My WH1C had about 10k on it, and was solid until the 1/4" brake line I was using to feed it failed.

Seems like so many people make the oil feed way more complicated than it needs to be, and then still don't get it right.

A not wore out cummins will have 60-80lbs of oil pressure, and they are fed NON resricted with a line just a little bigger than -3.

yea, oil feed and returns on holsets are driving me nuts, there's so many conflicting posts i'm about to say forget it and keep a garrett fed from the head unrestricted

but seriousely, last time i checked pressure at my OFH it was HIGH, pegging the gauge by redline easily, but that was on the "dirty side" of the filter.

I took and machined a fitting to use a banjo bolt on the OFH clean side last night, then filled and drlled the banjo to .085" i'm hoping with a garrett return flange, 2g oil pipe cut in half with a hose connecting them i will be fine, I can't really afford to buy 100 dollars + worth of AN fittings for the return but could probably make something, just pulling the pan in my physical condition is a painfull and time consumig ordeal (to weld in a larger fitting)

I'm trying to figure out what combos on the feed side are letting some get away with this exact drain while some can't use anything smaller than the 19mm+ holset recomends and since i don't even know how my machined turbine housing is going to perform i'd hate to do all that modding for it to barely spool , cause then i'd have to get a 2g mani, BEP mitsu housing then weld a wastegate flange into the manifold, and all just to run this thing when i could have just put a gerrett combo together in the BB CHRA i have and probably gotten the same results

 

[bastarddsm]

Don't run it hard with that restrictor. I allready told you that you have at least 20psi less on the clean side of the filter. Your drain should sufficient. Mine is about 17mm at its smallest. It jsut needs to be smooth and not kinked. I used to runa 1g drain on mine with no issues, but the new turbo/mani wouldn't work with it.

seriously, run it un restricted off the clean side with ## 2g drain setup. Just make sure its un kinked. If it smokes restrict it back to like .125"

 

[turboglenn]

starting off no restrictor tomorrow, the smallest opening in my feed setup is .123" at the banjo bolt inlet OEM size, could make it larger if i need and pressures are within range. I started a thread that will document the install, the oil pressure fromstart to finish and then strreet logs for all, hopefully they aren't embarassing.

If needed i can restrict down to .090 - .085 i'm hoping there's no need
