Who need's a new GTX2860R Gen2 compressor wheel and housing?
TURBO IS DONE! ****!
It felt smooth, when spinning by hand, no signs of oil anywhere, no shaft play, PO said it was fine except for the slight compressor wheel damage it had. Sucked something in... Yeah, sure...
Started the car up, no leaks at idle, went for a drive and tried to get very easy into boost, turbo sound was somehwat "high pitched" and immediately a big cloud of smoke appeared behind me. Turbo also did NOT build boost.
Turned car off, scratched head, fired it up again after a minute and it smoked even more. That's 400m driven! Drove home around the block and I was contaminating the whole street with white smoke.
Opened hood, oil on the shelf, oil on the CHRA, oil everywhere. Pulled intake, oil in compressor wheel area, this thing is junk.
Option 1: Put GT2560R back on, have fun and wait until winter to put something new together
Option 2: Buy new GT2860R CHRA, put GTX compressor wheel and housing on it, enjoy new turbo, sell GT2560R
Option 3: Sell GTX2860R and 2560R and buy new complete GTX2860R OR G25-550, but that's A LOT of cash
Option 4: Part out
I'm leaning to option 2, as option 4 is not going to happen and 3 is more cash and the results are the same? Option 1 is also not bad, as the car was fun, but I want MOAR! That's why I did all this stuff
Thanks for the tip. Looked into Pulsar, they offer a CHRA for a GT2860RS for 255€ with dual ball bearings and inconel turbine wheel. Emailed them, if the genuine garrett housings and wheels fit (which I think they do, just want confirmation).
Can your buddy top that? Would be a quick and easy way to get this thing going again.
Also mailed TurboRebuildUK, where I got my wheel from, they also offer BB-CHRA rebuilds and balancing, maybe same price and I can save it, will see
Devastating update and rehabilitation of the PO:
I'm the dumbest POS under the sun, like REALLY! Please blame, flame, whatever me! Learn from my mistakes AGAIN Sitting here at work and suddenly everything comes clear to me.
So, as I'm stupid, I forgot to order an OIL RETURN GASKET and thought I'd be a genius, when I take some kind of paper gasket from another vehicle I have laying around. Cut the outer shape, cut the bolt holes... Dude, that looks great!
And as I'm even more stupid I DID NOT CUT THE BIG OIL RETURN HOLE I blame it on a sunstroke yesterday and running out of daylight Well, maybe I shouldn't.
You can't imagine how I feel now!
Sad thing is, I have to pull the turbo to fix that issue and I'm not even sure, if the turbo got damaged by this quick excursion of excessive oilpressure I don't think there is much information of totally clogged oil returns.
Will keep you updated.
Edit:
Turbo felt super smooth yesterday after the oil drama, no shaft play, nothing. I don't know if it wouldn't spin perfectly fine, when the seals are blown? Help!

I'm going to be optimistic and say it's unlikely you did any serious damage in the 400 meters you drove around the block, especially since you weren't in boost.
Pull the turbo off, inspect for damage, fix the gasket (lol), and if it all looks ok... stick her back on and let's go boosting!
That's what I'll do. Pulling the turbo after work, that's the 4th time I'm pulling one in that car, so I should be fairly quick. Nothing rusted, downpipe is held on by bolts for testing purposes.
Fingers crossed, otherwise a new CHRA it is. I just want the extra 30-40 whp and maybe a few ft-lbs of tq
edit:
The guys from TurboRebuildUK said to do exactly what I'm going to do and what you guys recommended: Pull turbo, clean, fix gasket, put back on and burn that sucker free!

Well, 3h later wrechning after work and the car is still smoking badly.
Turbo was oily on the inside, downpipe, even a little bit on the exhaust manifold. Okay, attacked all the **** with brake cleaner, put a new gasket on, reassembled everything, startet it...
SMOKE!
Thought it maybe takes a while to burn all the residue out of the turbo, but it was pretty clean, when I put it back on, the outside was fart dry after my trip around the block (4-5min).
Still smoking, still high-pitched spooling sounds, did build a little bit of boost, but only 3-4psi in 2nd gear. Smoked like crazy. I think this thing is done.
I now pull the trigger on a complete Pulsar GTX2860R Gen2. 515€ including shipping is hard to beat and I can use all my Garrett housings (confirmed), so the cops see "Garrett Turbo", when pulling me over, that's what's written in my car papers. Can sell my new compressor wheel and the pulsar compressor housing to anyone who wants to upgrade their GT2860R/S and the 2560R aswell, should give me all my money back.
Nope, these are GEN1 (!). ****! Housings are different... I'm going to sleep, will overthink everything tomorrow. They sell GTX2867R Gen2, another option, but I suppose more lag. AND no Garrett housing..
That's three times pulling the turbo in 2 weeks, I'm running out of steam.
We're building a house right now and I can't justify a new 1300€ turbo right now, hope the Pulsar is as good as everyone says it is...
Pulsar mailed back, they sell a GTX2860 Gen2 CHRA for 409€ + taxes/fees. I don't know what to do.... They said, the GT2860R CHRA for 250€ does NOT fit my housings, but isn't the only difference in GT/GTX the compressor housing and wheel?
Can't I pull the the snap ring behind the "carrier plate" of the compressor housing, change to the one from the GTX, put my wheel and housing on and call it a day?
The rotating assembly is likely balanced as a whole unit and not the individual components so it will probably have issues with being swapped that way. And some have different housing mounting components so you may not be able to interchange at the snap ring.
Did you get all of the oil out of the intercooler? It is difficult to do and usually requires standing it on end for hours to drain it.

Lol, dude.....I bet the turbo is ok they are pretty resilient.
edit : I see that didn't work. The only difference in gen 1 and 2 is the compressor wheel and housing. Everything else is the same.
@six: The oil didn't really get into the intercooler piping, that was dry. It only ran these few hundred meters and it "pooled" in the compressor housing by the wheel.
@andy: Is the normal GT2860R also the same? I know the turbine is, but can one change out the compressor housing? That would save me a lot of cash, even if I let it balance for 80€.
I think, I should put my test pipe in, because I have a very expensive 3" cat in the car, poor thing doesn't like to be full of oil I suppose... It's smoking really bad Like so bad, I can only drive it at night, because everyone is watching at me and yelling
What could be the reason the turbo doesn't build boost like it should do, if its totally free and smooth by hand and has no shaft play?
And the stupid sound it makes... Do you guys think that it takes like 10 miles to get the oil out, even if I cleaned it very well? I haven't had such problems, so I'm just unsure at this point

Maybe the bearings got hot enough to turn some oil into shmoo and clog the feed when you initially had it covered? Have you tried blowing some compressed air through it?
No compressed air at my house yet, but I took the feed and drain out and everything looked clean like it should be. Oil just seeped out, when laying it on the side

The 2860rs, GTX 2860gen1 and gtx2860 gen2 all use the same CHRA and turbine wheel. Yes all you need to do to convert any of those is the compressor wheel and housing. My turbo was a gen1 then I swapped out the housing and wheel and didn't even balance it and it's making 400 so who knows lol.
