Just did the first start on my build and as soon as it got to temp the turbo started smoking like a freight train out of the downpipe and puking oil. Theres oil in the cold side as well. My oil return goes to the timing cover and is downhill the whole way with no kinks or dips. I tried putting a restrictor in and had the same result. It's a large amount of oil. Are the turbo seals bad out of the box? First time dealing with turbos/boost.
Pics of drain setup? What did you use for fitting on both sides? Measure the ID of fittings?
Soundsd like it may be a turbo problem, but your feed and drain is less than optimal as well. Esp if you have any sharp bends or use cheap china fittings with small ID's.
3/4 to 1" drains are whats optimal. Not that some don't get away with smaller.
ID of an S400 based turbo drain
ID of a -10 AN fitting.
Straight from Turbonetics... and their drain diameters aren't as large as the BW.

I'll have to find a picture, I know I have one. It's all -10 Fragola fittings. 2 45s coming out of the turbo to snake around the merge then a 90 into timing cover.
I should be fine with the setup. There are multiple setups I've seen with even worse angle having no issues. I shouldn't even need the restrictor. I don't think it's a drain issue, it's a serious amount of oil, not just puffs of smoke.
Why the high pressure pump? 72 psi at idle is way overkill. No need for pressures that high. Change the pump to either a stock pump or a high volume if that'll let you sleep at night. You're probably blowing through the seals with the pressure so high. A restrictor is just going to reduce the volume, not the pressure. If anything, the pressure is increased even more. Remember to add additional oil if you go with a high volume pump so you don't suck the pan dry.
I have the S475/92, I use a #4 feed and #10 return.
I come out of the turbo with a straight fitting down to a 90 deg into the
pan right below the balancer (it was tight) and no problems
I use a stock ported pump, 45 PSI at idle.
Makes me think you have a seal issue, unless somehow your return is blocked-was there a clear shot behind the timing cover where the fitting goes
This is why I don't understand my issue. It's not a super tight fit or anything. My line is angled but not insane. It's something that should work but isn't.
I called Forced Induction yesterday and we went over my setup and issues, they assured me the high pressure oil pump is no issue and I should be running the Borg without a restrictor.
They are adamant that my oiling issue is my drain, especially with the 90 degree fitting at my timing cover, and the 45 coming off the turbo.
I have seen the same setup everywhere, but not on a Borg. Maybe they are special and have more drainage than most, I don't know. But I went ahead and took the easy way out and have a Turbowerx Nano scavenge pump on order. I've been doing this build for over a year and just want it done already.
I found the pic of my drain finally. You can see how there's really no other way I could run it with this turbo orientation, at least to the timing cover.
I might be able to fit a 70 degree fitting there, definitely not a 45. It's pretty tight with the belt there. It doesn't matter now, Turbowerx pump will take care of everything.
Maybe run it straight out of the turbo and into the pan along the side. You'd have to remove the pan to install the fitting, but that may be what it takes.
I guess I am not convinced its a drain problem, here is an old pic of my orig setup, still the same way on the new engine-#4 feed, 10 return, 90 into the oil pan. Of course all setups are diiff, anything is possible
The only thing is what's behind your fitting in the timing cover-I have never tried it, but I wonder if you ran the engine for a few seconds w/o the return
installed in the timing cover, maybe stick it in a 1 gallon jar, see how much comes out-also examine the hose for a collapse or something-my BW is the cartridge type, they said use the feed unrestricted, I think rest. was used for ball bearing.
Just a thought, maybe far fetched, could the engine be pumping oil out, maybe a bad cyl-not sure if you have a PCV system and how its plumbed, but using an LS 6 system mine was sucking oil out

Yeah I tried running it with the drain disconnected and with the restrictor there was just a trickle of oil, FI said it's because I have that 45 right off the turbo with no chance to let it drop straight down. I'm going to run it without the restrictor and see what I see. It really seems like the drain hose is clogged or something but I haven't taken the fitting off the turbo yet, I will tonight. I can always sell that Turbowerx pump, but I think I'm going to need it. There is no other way to run this drain gravity style with my merge curving up where it is, it's already resting against the merge and I don't want to burn up the hose even though the merge is wrapped in DEI and I have heat tape on the drain hose, I'm still worried about it.
I have a Mighty mouse catch can btw. One connection is on the intake manifold by the TB and the other is on the passenger side valve cover. I've only idled this anyway so there shouldn't be much pressure in the first place...
Ditch the restrictor. Get yourself some steel drain flanges super cheap off ebay and hog them out to ¾”. Then weld some ¾ steal tubing oil drains on the angle you need. Make the drains as long as you need to clear the hotside, then start with the rubber tubing. Something similar to this with longer steel tubing section.
If that doesn't drain properly with no help from a pump, it's the turbo.
