The way you word it...makes it sound like the turbo is chinese junk ? Otherwise you'd be saying it's a Garrett, Turbonetics, BW, etc etc etc
Are there any ID tags or better info as to turbo type ? It most certainly will not be anything unique that could not be repaired locally...unless it really is some chinese junk.

The exhaust is blowing smoke now...ok...but did this happen suddenly, over a period of time, have others or yours ever had oil consumption or smoke problems ? If not then it would be hard to say the oil drain is the culprit, as bad as it does look.
And 10 kits are enough to know whether that design does work, unless the others dont actually drive their cars ?
Have you ever spoke to the owners of any other kits ?
The turbo is manufactured by the company that makes the kit in the US, so it's not Chinese and it's not an off the shelf unit.

The exhaust has always smoked a little, but is now smoking a lot. I'm talking big clouds, usually when pulling away from stationary.

I've not spoken to anyone else who's had the conversion as I don't know anyone else with it. I did some more Googling last night and it appears that it has happened to others in the US, but is not that common. One guy has fitted a scavenger pump and after having the turbo refurbished no longer has any smoke problems, so I think that may be the way to go.

I'm 100% certain they don't manufacture the turbo. Remove it and take it to a specialist.

You may just be talking a £150 refurb.

There is no way whatsoever the turbo is a totally custom unit. None....zero. And wording the way you describe...just shouts Chinese although it may not be.
Have you any details of the unit, the kit...any details at all ??

If you are going to add a scavenge pump get the Turbowerx Exa, or their smaller Mini Exa would probably do fine

From what I've been told, 911 turbos use a scavenger pump to get the oil back to the engine, so I'm wondering if I'll have to do the same.

Pretty standard practice where the return is lower than the sump. Even some 4 cyl OEM turbo-above-sump oil returns have a special inlet on the sump that the oil pump draws on, to avoid any kind backing up problem in the turbo.

Nobody knows the Porsche flat 6 better than Porsche, so if they felt that was best way to deal with it, I'm surprised the kit maker didn't do the same. OEM installs are usually the best template to copy unless building something radical. But as is so often the case in the aftermarket, turbo 'kits' seldom are. There's always something the customer has to sort out or fix themselves.

Odd that yours is allegedly the only car this has happened to.

I spent an hour or so Googling last night and found some people in the US who've had similar problems. One has fitted an electric scavenger pump to resolve the issue.

It has nothing to do with Porsche, it has everything to do with where the turbo is mounted and whether gravity is sufficient.

A monkey could get it wrong, or right.

Looking at any images I can find of this kit....the turbo just shouts Chinese. Plain castings, no markings, probably a GT35 copy or similar. Nothing fancy at all. Take the turbo off and to a reputable turbo repair shop near you.
Although very odd on their site there are so few pictures of their product. Some does look good quality, so you'd think if everything was they'd be wanting to show it off.

Some re-sellers have a few more images or google brings up some. Either way the turbo is nothing fancy or special

Get turbo fixed, ask fixer why they reckon it failed, and if they do believe lack of oil return, then add a scavenge pump.

As it's only a single turbo, their Mini would be more than adequate.

Or if there is plenty of room, just the regular Exa.

Well yeah, which is what I said, but not quite as bluntly as you. It's true though. Always look to OEMs for solutions because they design things to last 100K+, not 20.

When will a turbo mounted lower than the sump ever have sufficient gravity? Never, as far as I can tell.

The pictures are poor, it isnt easy to tell how bad the mounting positions are or heights. And if it was a good BB turbo these need such low volumes of oil....even a poor gravity drain is usually ok.

But this just looks like a regular cheap oil journal turbo.

But also odd that the kit doesnt want a scavenge, apparently it works for other people and it lasted in this case for maybe 20-30k ?
So maybe it's just a case of st happens, I'd have expected an inherently bad design to have suffered some symptoms or problems wayyy before that mileage.
