well, i dont try to make a kind of groupsbuy right now,
if you see to the seller, he got those turbo's for sale on ebay right now for 222€!!!!
i ordered one for myself today.
i paid +-281€ for it, dilivered.
i think he still got some turbos for sale.
he offered me one for 260€ including shipping (but he wont use ebay, the lower cost is becouse he dont got ebay-fees...)
if you want one, i think this is a good price.
offcorse i will leave my feedback from this turbo on vwdiesel also :wink:

well, i recieved it today, i post pics later.
the turbine (inlet) is A/R 0,64, compressor (outlet) A/R 0,61
the oil ways look difrent to other turbo's i saw (under angle of 90°)... i post my question one of those days.
what should be the max safe pressure from this thing.
ooh, it looks very big

this is it
the oil ways under angle of 90degrees
i think this is the oil supply, as you can see there are 2ports :?: :?
i think this is the oil who returns to the carter
i never saw a turbo with oil ways like this... normal the supply must be up just with a little bit tollerance and the outline-oil downwards.
i found some pics from the turbo original mounted: (this should be a Isuzi, but there should be no big difrences...)
someone got a theory for the 90angle degrees?
why are there 2 oil supply lines?
with a normal turbo you can see when the oilsupply wise up the turbo is pounted right, but how can i see this now :cry: i dont wanna blow my shaft...

The small hole is definately the oil supply. Tons of them are designed like that.

The allen screw is a part of retaining the center cardridge internals, I will take some pictures of my VNT-boom if I get a chance.
Measurments on the turbo would be useful and welcome Benjamin :wink:

The allen heads are not reatining anything but themselves. I'm quite sure they are machining plugs for the internal oil gallery that starts from the supply port on the bottom and lubricated the center bearing stick from above.
I tried to get one off but the flats were just sheared off when I hit them with the impact socket driver :twisted:
The center section is one piece cast/machined I don't know what those could be used for apart from the explaination above --^

That turbo was from a toyota D4D, its a GT1749V but the main design features are more or less shared among the same generation lines.
Luckily I don't have a dci but I'm studying what turbos might be suitable for my toyota 2.4 project. I could use the tubine and compressor inlet and outlet diameters for reference as well as the compressor housing diameter to give me an idea of how big that bad boy feels
I've had poor results with the 1749 before so now I'll be shooting for the biggest I can find !
Thanks

tw your turbo is watercooled, that's the two identical holes on the other flat surface, which is in and which is out is up to you.
Having seen how small (0.5MM ?) the oil passages are in the center bushing of my 1749 I can easily think the unit is not exactly flooded with a great oil flow. Watercooling is mandatory IMO

yeah, a gt1749v is just to little for a 2.4.
i think if you got a good tuned pump a gt2559v will perform very good.
for a 1.9 i cant say how fast it gonna spool, but for a 2.4 i think there is no problem at all.

I'm afraid it might not be big enough for my long term plan for for a start it will probably work...

i dont have a map.
if you wait couple months more it will run on my 1.9 and you can see the lag yourself.
its just a gues, but i think you better can go for a twin turbo if you are thinking about more hp, i think it will be pretty laggy on my engine, maybe it just wont spool... we will see.
