T3 Turbo Upgrade...

So I thought that I would start my own thread on this subject.

My thoughts are to work with a bunch of member on here who can piece together my crazy hair brained scheme to upgrade our current GTB turbos into the newer GTD turbos.

I need to do some more digging but I believe that the factory GTB2056 turbo found on the north american Touareg's should be able to be upgraded to a GTD style turbo.

I have a source for the GTD VNT assembly, but honestly think it better for anyone interested to buy a used GTD turbo. The reason being that way you have the factory turbine and compressor wheels to go along with the VNT assembly.
Yes i'm sure we could find a source for chinese turbines, but i'm all about doing something the right way, and one time.

The GTD2060 converted GTB2056 should be good for roughly 350 crank HP with the emissions stuff in place, and there is also the GTD2263 which can use the GTB2260 as a base turbo.

It looks like since we have to keep the most of the factory turbo intact and just swapping over the GTD VNT assembly, turbine, and compressor wheels and the possibility of using parts from a used GTD I am going to recomend that anyone wanting to do this also uses a rebuild kit with all new parts for the bearings, seals, etc...
There is a place within 2 hours from me that can balance the rotating assembly up to 400,000 RPM

I'm just trying to help everyone with my crazy idea to get more and reliable power...

Ive been seriously eyeing up this turbo right here. https://www.darksidedevelopments.co....gtd2060vz.html


Unless its drastically cheaper, it almost makes sense to go big or go home and have a turbo capable of 500+hp. If anyone here is even considering a turbo upgrade, you better damn well consider at a minimum a pump upgrade as well.

That's always an option, darkside makes some nice stuff.

I'm guessing for the GTD2060 if utilizing the stock GTB2056 housing, add in a used TD turbo, and having it rebuilt would roughly be $1000

Did you ever spell out the specs of the turbo you got from Europe vs the stock GTB2056?

Sure, what are you looking for?

I have a GTD2263, so slightly different that the GTD2060.

So the turbine housing is in fact larger so simply swapping out housings without machining them is out of the question. IE, buy a used European 2263/2060 and swapping out the housing to match our exhaust manifolds.

The only machining on the GTB housing is for make a place for the mounting "plate" that holds the VNT assembly in place. A new mounting plate will also be needed but I think I have a place that can water jet some SS310 for the job.

The rest of the GTB housing is fine

The plate has the red arrow in it at 54-56 seconds

Are you reusing the GTB electronic actuator or are you swapping over the GTD one?
