There is a gaggle of good deals on Garrett VGTs on ebay:
GT2256V $60 (http://cgi.ebay.com/ebaymotors/MERCEDES-GARRETT-TURBO-AL0007-GT22V_W0QQitemZ270238060576QQcmdZViewItem?hash=item270238060576&)

Liberty Turbo 3 (http://cgi.ebay.com/ebaymotors/GARRETT-TURBO-35242115F-763360-1_W0QQitemZ270238076314QQcmdZViewItem?hash=item270238076314&)

The third Liberty turbo is the 35242115F version which is a GT2260V. Other than the vacuum actuator it seems to be exactly the same as the more common 35242112G model so I believe that all of the Jeep Liberty turbos are GT2260Vs!! :dancefool

jeeze.. do I want to splurge and get a VGT... soooo tempting

No excessive shaft play yet they all say that they are cores for rebuilding. Is he just covering his backside?

probably

Yes. I got my turbo from him with the same description and it is in perfect shape.

Yes. He has no history on the turbos so he always assumes they need work to be safe.

I doubt it. Notice the third one has a nut on the compressor wheel while the other two do not.

I did miss that nut. The numbers cast into the housings and inlet and outlet sizes for the compressor and turbine seem to be identical though, so I definatly think they are the same size turbo.

I wonder how the shaft is held together on the other type. :confused:

So are these direct bolt-ins for the stock turbo? My gut instinct makes me think not, but it sounds like you guys would be the ones to know.

Are these an upgrade over the stock units? Better design? Better tech? More efficient? Less lag? More boost? What?

Inquiring minds want to know. School me. Please.

So are these direct bolt-ins for the stock turbo?
There are only two direct bolt-ins for the engine, the stock T3 and K26 that Mercedes used on them.

Are these an upgrade over the stock units?
Definitely yes.

Better design?
Yes. The T3 series turbo is a 1970's design. These turbos are the more modern GT series which have the benefit of computers to help refine the design.

Better tech?
Yes, the GT series is more simple and more reliable.

More efficient?
Yes, the turbine and compressor wheels have much better aerodynamics to move air more efficiently.

Less lag?
Hell yes! Thats the key to the VNT/VGT greatness. The vanes on the turbine side change the pitch and velocity of the exhaust gasses to act like a tiny turbo but flow like a big turbo. Kind of like putting your finger over the end of a garden hose.

More boost?
Yes. The K26 turns into a heat pump at 14psi and the T3's efficiency peaks out around 20psi. Although they can go higher, their terrible efficiency at those pressures means it hurts performance rather than helping.

What?
Its not easy to install one.

Adapter plate to mount to the exhaust manifold
Custom oil supply and drain lines
Adapting to the intake manifold
Adapting the exhaust pipe
Installing an adequate air filter system,
Controlling the vanes
and about a dozen other small details.

Thanks for the info!

Since I have the T3 (which appears to be the better, more efficient of the two stock units), I think I'll leave it for the time being. I have several other simpler things I need to find time to bring back up to snuff before I get into anything radical like a custom install or max performance mods.

Once I have everything back up to par, and an EGT & boost gauge installed, then I'm thinking a simple wastegate pressure controller should do the trick for me. Since I'm more interested in economy - rather than flat out performance - I'm thinking the T3 will be able to give me all the boost I need.

The wastegate controller helps quite a bit in faster boost.

My boost controller failed, wont be using that again.

I just noticed that the 60$ one has a different looking compressor geometry. Any idea what difference that would make? I'm assuming that would make for a vastly different pressure map.

I verified mine with Garrett employee as GT2059V. There are different flanges so who knows. But I know mine is what it is.

It's just a different compressor outlet. That is the turbo Forcedinduction has.

How did you get a hold of them? I tried, but could never get a reply. It seems really odd that the smaller displacement sprinter engine would have a larger turbo.

No, Look at the compressor WHEEL itself its drastically different than the others.

It looks like it was run with a K&N. :D

The compressor wheel is shot.

Well, I bought one... We'll see if its any good. I need a new turbo anyway, figured this would be a good route. Now that two of our members are using them.

Talk to diesel kid for the mating plate. I think he was charging $85 for it (but dont quote me).

Thanks, but I have access to a mill :). Otherwise, I don't think that I would ever tackle such a project.

If you want I can give you the turbo side flange schematics. I also have a 2d mockup of what we ended up going with.

Got Your PM, Thanks!!

If you look in the "need something fabricated" thread there are cad drawings of the adaptor.
