Hi,
i was searching with my buddy for Garrett GT2559v turbo's. This IS the biggest Garrett VNT turbo!
i'm talking with a vendor on ebay to make a deal. (he got 100% positive feedback over 190deals)
He got 5 VNT-25 turbo's.
Who is intrested for one to????
the price gonna be something like 300-400EURO (maybe less than 300EUR) shipping in for a GOOD-condition turbo.
who is seriously intrested???
this is a photo from it.
(http://i50.photobucket.com/albums/f305/joericambi/turbo-71b.jpg)
The turbo's are from Renault with 177hp, on a bmw they use also the gt2559v, he's making 270hp, with chiptuning they make 340hp.
Do you guys think this turbo can spool up quick? or shoult it be to laggy? (1.6/1.9 use)
Greetz, Benjamin
@Admin: i dont got no any idea where to post a "asking for intrests" vs "kind of groupsbuy". :oops:
-
I am... i ll see you on msn
-
new or used
-
spool up should be pretty quick as to compared to wastegated turbo's
-
What controls the VNT?
-
new or used
they are used. The guy only sell turbo's on ebay, with 100%@190deals. I think very well we can trust this.
What controls the VNT?
the actuator need to be rebuild, problebly the turbo also need to be rotated (so the oil-in wise to above).
Use the search for more knowledge :wink:
Dont forget this one http://www.vwdiesel.net/phpBB/viewtopic.php?t=1306&postdays=0&postorder=asc&start=0&sid=2a86bb6a3d8ec250a546cc60750e4a73
Greetz, Benjamin
EDIT:
condition, this is what he mailed to me (i cant go visit him, i'm from belgium, the seller is from UK.
The turbos are all used, all about 20,000k and in good condition.
You are welcome to come and look at them.

Who is seriously intrested more for the biggest Garrett VNT turbo?
This is the original link. (but our price gonna be lower offcorse)

i'm interested... but i dont have enough coin...
how hard would this turbo be to retrofit it to a 1.6?

Named tintin his project:

the oil line need to wise to above
(http://img116.imageshack.us/img116/2331/entrhuilecorrect9nm.jpg)
so you need to redrill some
the red holes are original, becouse you need a other angle against the oil suply, you need to redrill on other degrees, the red ones
(http://img320.imageshack.us/img320/3858/filet5dp.jpg)
You can rebiuld the original vacium actuator to boost controlled or you can put a actuator on from a waste-gated turbo wich is allready boost controlled.

(picture from Jetman)
So yes there are some custom works, but if you are technical you can do it.
When i see those pictures from the gt2052v and the gt2559v they look pretty well the same, maybe the exhaust will fit? :P the cold side is problebly other sizes... but it got +- the same style, isnt?
Greetz, Benjamin
-
i'm interested too....... i dont have enough money for the moment :cry:
which is the size of the compressor wheel?.... 59 ??
which is the size of exit of exhaust on a vnt25 ? .. very important for me, because, if it is similar like the VNT 20 (approximately 1.5 inch.) is not large enough for me.

compressorwheel 59.
i dont know how big the exhaust is, i think its similar to the vnt20, that means you can use the same exhaust, but i'm not shore about this!
i got a gt2052v and a gt2252v, i will look or there is a difrence between the exhaust to make a reference...
@Named tintin (or someone else), is my explaination about the modification right to convert the oil supply to up? 3drills thats all?!?!!
Greetz, Benjamin
-
I dont know if the vnt 25 need to be reclock.
I running over 6 month with my car and no problem with my reclocked VNT20, can be that I should open it to see what it is that this hole.
-
if you say now you want a turbo, you NEED to take it, otherwise i'm ******.
I will get the 5turbo's, i will inspect them, if there are problems its all between my and the ebay vendor. This will take about 5-9days.
You pay to me, to my bancaccount or paypal, i send the turbo to you.
If you want, we can do this over Ebay, but then you have to add the ebay costs.
The final prices depends on the shippingcost.
final price exclusif shipping ,GT2559v from Renault will cost: 300,00EUR
sebzero belgium: you can get it in Sint-Niklaas, or shipping is 11,20EUR, it will take about 2days.
libbybapa usa (i need your postal code + city) it will be between 52EUR
RabbitGTDguy usa 14905 NY (i think this is New York) it will be between 52EUR
(usa shipping: i found one for 52EUR, i THINK i can find one for 32EUR i'm searching)
the shipping period, i dont know, i still need to find out, i think it will not take longer than 3weeks, problebly faster. i'm still searching for good shipment methods to USA/Canada.
(its my understanding jtanguay & NamedTintin are not intrested)
(all prices are in EURO)
_______________
are there more intrested guys? let me know!
Greetz, Benjamin
(post under construction!!!!!!)
-
ARF!! If I had one week more I would take some too.....
I have just bought a quattro kit, is necessary to leave me time to breathe one can :lol:
In any case, I will try not to miss this offer, I t'en give again news.
-
There are still turbo's for sale. (at least 2)
if you want one, let me know, this weekend i try to order, if i dont got enough buyers, i cant buy them...
turbo cost 300EUR
shipping to:
canada & usa: 52EUR (longtime shipping -35EUR).
Europe24EUR - 28EUR. (depends where you live)
if you are seriously intrested, let me know so fast as possible (the seller asked me to not wait long)
Greetz, Benjamin
__________________________________________
EDIT: 20november
becouse there are no realy intrested people who got the casg right now, the deal NOT go on.
You can always PM me if you got questions.
-
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:

I might be looking for a GT2256V..
-
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 8)
Greetz, Benjamin
-
this is it 8)

the oil ways under angle of 90degrees
(http://img295.imageshack.us/img295/3790/kopievanpict0067ul7.jpg) (http://imageshack.us)
i think this is the oil supply, as you can see there are 2ports :?: :?
(http://img231.imageshack.us/img231/6401/pict0065dt3.jpg) (http://imageshack.us)
i think this is the oil who returns to the carter
(http://img92.imageshack.us/img92/6229/pict0066ie0.jpg) (http://imageshack.us)
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...)
(http://img58.imageshack.us/img58/1599/2288kz5.jpg) (http://imageshack.us)

(http://img58.imageshack.us/img58/5658/2678gs7.jpg) (http://imageshack.us)
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...
Greetz, Benjamin
-
looks to me we the turbo's are not 100% the same.
Anyway, thanks for the better expenations

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 --^

what is "allen"? :?
wich measurments do i need to make?
is the coolant by water or oil?
@2446: from wich engine is your turbo?? you own a 3.0dCi? :D
Greetz, Benjamin
-
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.
Greetz, Benjamin
-
I'm afraid it might not be big enough for my long term plan for for a start it will probably work...
-
do you happen to have a compressor map for it BTW ?
-
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.
Greetz, Benjamin
-
turbine housing A/R.64, compressor housing A/R.61
compressor inlet diameter 65mm / outlet 45mm
turbine inlet diameter 42mm / outlet 46mm
did the oil supply/outline from your blown gt1749v wise down or can you turn it some degrees? (with normal turbos i know the supply need to wise up, outline/exit-oil down, if the degrees are wrong, the beering will blow in a time, normal tolerance is about 15defrees to each side with the 'normal' turbos)
i wanna see that socket/flange from your supply/outline from the oil
Greetz, Benjamin
-
thanks for measuring, I thought it would be bigger but it's a good stating point.
The oil supply/return is a simple flat flange on which 2 steel tubes are brazed, the oil supply tube has a banjo fitting at the other end and connects directly to an oil supply port on the engine block, the return dumps into the block at the very bottom end and is connected with a rubber hose. The lines are vertical but I don't see a couple degrees off being a problem.
The center cardridge and turbine housing can be rotated, when I did it I just had to drill two holes, one for the roller pin that indexes the position, and one for one of rollers of the vanes ring control that was in the way of the actuating finger. Once you open it up it all makes sense :wink:
-
is there a gasket between the flange for the oil and the turbo?
(and between the coolant flange and turbo?)
yea, rotating is easy if you got the worktools, its not my first opened vnt :wink: its much bigger than a gt2052v wich i got.
i believe you can push this turbo till 300hp on a 2.4, alltough, i dont know what is the max nominal pressure for this unit.
Greetz, Benjamin
-
Yes, there were gaskets on both mating sufaces. Original ones were some kind of multi-layer metal but I've successfully used custom-cut cardboard too ;)
The engine head will have blown a long time before 300hp :lol:
-
those max15° off is what a guy who working in a turbo rebuild shop told me.
Greetz, Benjamin
edit: its max 30° to each side, but its not the best, you better go for 0° !!!
-
How did the Vnt 25 work out for you? there has not been any updates? Thanks J
-
Hi,
i was searching with my buddy for Garrett GT2559v turbo's. This IS the biggest Garrett VNT turbo!
Nope. That's really small Garret VNT turbo. I have few REALLY big ones like GT42vnt. it weights 40kg and it's good for 600-700hp on diesel. I also have smaller GT37vnts and GT32vnts to play with.
Here's GT42vnt. This one is going to my friends 3,0L V6 gasoline dragracing car.
(http://i16.tinypic.com/4ckhmwn.jpg)
(http://i19.tinypic.com/2djv59d.jpg)
We have also project with MB300td 12-valve with modified GT37vnt. Aim is 500hp and torque seems to be unbelievable.
-
Okay, so there are bigger ones. What size VNT would equal a Garrett TO3?
Any ideas? I figured it was about the size of a 25? Did Garrett make a 28vnt?
I'm in the USA and they don't offer very many VNT's as stock units.
thanks
-
Can you post pictures of that GT32v?
-
oke guys, i did my first drive with my pump turned back (maybe about 60hp or so), it pulled 0,5bar/7psi with the vanes somewhere between closed and open. i believe it will not be to much lag. :D
but...
i made a flange with the connections for the oil supply & out.
it was a normal flange with a metal gasket between (i made this myself, with the same matrial like the manifold gaskets -not copper- but dark grey gasket-.
...so oil was leaking between it, not very much i think but enough to damage this turbo, it was like brand new, now it have medium or even large play :x :x :x :x :x :x :x
(http://img92.imageshack.us/img92/6229/pict0066ie0.jpg)
does anyone know how the OEM flange + gasket looks like? or so
i know some other vnt turbo use this same flange, any pics or so.
i hope someone can help me
Greetz, Benjamin
-
Maybe you can machine yours to take o-rings?
-
i wish i could use a kind of adaption becouse if i ever need a new turbo its less work. thats the reason why i wanna see the OEM flange.
i you look good to the picture you can see how the previous gasket problebly looked like, maybe gasket with copper o rings in like a headgasket is build?
Greetz, Benjamin
-
I've seen gaskets from both "paper" and "metal sandwiching o-rings" style. You need to make sure your flange is super flat, it can warp a fair bit during welding. I don't think your flange/ gasket could have leaked enough to prevent turbo lubrication ? Maybe it's just broken in from a tight rebuilt ?
-
ok, its not broken, but just a little bit more play on the shaft, but still good, i was in a bad mood yesterday :oops:
tomorow i go to the shop for the original gasket.
2446: thanks to reply my post :wink:
Greetz, Benjamin
-
today i just ordered a couple OEM gaskets in the Saab garage. tomorow i will have them. it was like 1,33€ or so.
i also asked price for the OEM piping, its about 250-300€ for those :shock: i also have a picture from it now, i post it soon.
Greetz, Benjamin
-
ok, this is a technical draw from the Saab sale.
(http://img475.imageshack.us/img475/3811/03052007008rd2.th.jpg) (http://img475.imageshack.us/my.php?image=03052007008rd2.jpg)
after installing the gasket it was leaking even more, tried to make the flange more flat myself but finely i machined the gasket and now its up and running.
this is the metal gasket about 0,5mm height. as you can see this is a GM gasket, its becouse its the same engine & turbo.
(http://img475.imageshack.us/img475/1390/03052007009gc8.th.jpg) (http://img475.imageshack.us/my.php?image=03052007009gc8.jpg)
this is my manifold, a home made spacer with a EGT probe in and the turbo on (dont look to the vnt controller, it have to make again)
(http://img214.imageshack.us/img214/5562/05052007008nx4.th.jpg) (http://img214.imageshack.us/my.php?image=05052007008nx4.jpg)
i did a run and some feul quick adjustments.
the vanes are full open all the time, i had between 1200-1400°F, boost start coming on 2200 in 3-4th gear, with 3000rpm you have 0,5bar (no quick response) i had 1bar on 4000rpm. there is a little peak when it run a little bit fast. till now my T2 was much better.
i need to shim my main spring in my pump becouse max rpm is 4700-4800rpm in all gears. with 4500rpm i think the boost is almost gone becouse the feul cut is there.
the car run like 11-12seconds to 60milles/h 100km/h. :cry:
it have a 2,5" exhaust, its very loud and a open air filter.
there is a lot of sound comming to the exhaust, (i rather have a silent car), there is turbowissle, very cool but i dont know how good this is.
i hope to give better feedback soon when vnt control and better feuling is there.
Greetz, Benjamin
-
today i did the governermod (i gived it some preload to the main spring).
i drove and its realy go fast, alltough i cant say how fast...
after going to 5500rpm i looked to my turbogauge and it was only showing 1,25bar, when i stepped of the pedal it wa still there, my boost gauge blowed (scale max is 1bar).
becouse i was idiot enough i folowed my feelings and boosted again, i drove on the highway, there was no need becouse it was still give good perfomance but on +-180km/h@6000rpm i shift to my 5th gear. i have no idea what pressure i was making but the a hose fly off my turbo (bov sound). i stopped to put it on again but i noticed there was some water around my watertank... broken headgasket. :cry:
i gonna install a new headgasket, and a good boost gauge.
Greetz, Benjamin
edit, in fact i did one gtech but it was my first run with the new settings, shifted to low in rpm range, i did 0-60miles/h in 8,34sec. i know its slow but to shift that bad and no vnt controller i think it was pretty good. i didnt the 400meter, to bad. but it realy was a great time! governermod is awsome! i could rev higher if you feel the perfomance on 6000rpm but i dont dare to do that becouse i wanna save my conrods and pistons.
-
with the vane controller positioned like that don't forget to install a heat shield to protect it :)
-
it will be replaced becouse the vanes are closed on boost and open offboost.
Greetz, Benjamin
-
Is there any way you could get me the part numbers for this sheet?
ok, this is a technical draw from the Saab sale.
And you said you got the gaskets from a GM dealer?
I just got a center section from a VNT17 and the ports look the same as yours.

http://toy4x4.free.fr/passiont/vnt/
treu, it is problebly the same. 2446 his vnt17 was also with this center.
i ordered in a Saab garage, but they gave my the gasket with GM on it.
i think you can ask for the number on the picture, but just go in the garage from wich brand the turbo original came from and ask for the gasket. Or go to saab, renault, opel (gm), and ask for the gasket from a 3.0td with 177hp from 2005.
cant wait to boost again :lol:
Greetz, Benjamin
-
You must be pushing alot of fuel through your engine to get that much boost on a big turbo with the vanes open. What is the A/R on the GT2559V's turbine?
My GT2256V will barely hit 0.76bar (12psi) at 4800rpm (3.0L engine) with the vanes fixed open.
-
0,63 is the compressor (inlet)
0,45 or 0,49 is the exhaust side.
the EGT on full boost was something like 1200F.
I hope to get that head off today and take a look to my cilinderwalls.
Greetz, Benjamin
-
the head is off, the cilinderwalls look like 7000km back when it was stock, you can see the honing, no vertical stipes or so.
but i think for shure the headgasket is not blowed, i saw on my cilinderwalls 2drips, so if i go look very very close, i see 2 little holes in the cilinderwall :cry: its very little, like a couple 1/10mm. i try to take pictures. i dont think its becouse of the high rpm or (big?) boost or egt. i think its becouse of a fault from fabric maybe but problebly its from corosion or so.
Greetz, Benjamin
-
0,45 or 0,49 is the exhaust side.
That's for the GT2559V? That seems awfully small. Even my GT2256V has a 0,64 A/R on the exhaust side.
-
treu, it was like that for a vnt20 or maybe my stock turbo, i searched for the details again:
turbine housing A/R.64, compressor housing A/R.61
compressor inlet diameter 65mm / outlet 45mm
turbine inlet diameter 42mm / outlet 46mm
Greetz, Benjamin
