It would be best to go with a more modern turbo and at the minimum, I'd go with either a GTB1756VK or GTB2260VK depending on what mods you have done to your TDI.

IMO, I'd go with the most current turbo you can buy for the best performance you can get out of a turbo and that would mean going with either a GTD1752VRK/GTD1756VRK or the larger GTD2060VZK.
Here are a few GTD1752VRK/GTD1756VRK options:

https://gottuned.com/product/gtd1756...ck-1-9-2-0tdi/

If you wanna upgrade to a GTD2060VZ, it will require quite a bit of customization to make it work on a 1.9L TDI.

Then I think, I will choose one of the gtb series. 1756/2260. I was thinking that using gt2260v it might not be the best choice, being old technology, but I needed at least one more opinion. But what about KKK 2260 from audi? I saw it's full of them, even more than garrett? I was looking for garrett and found almost only kkk. Are they failing at high boost, or they cannot even load hi boost? Thanks!!!

What PR is your LPT pushing ?
And how many milles did your HPT last ?

You can get ball bearings in the GT25 frame size. Probably just need to get the CHRA and move over the wheels and housings.

Garrett's Z-bearing technology may help too.

The permanent solution is to bypass the HP stage at the top end.

why do sequential when I can do straight compounds? Whole reason I went with compounds is to get the breathing there without needing to buy a camshaft.

LP is making 25 PSI, HP bumps that up to 45
iirc the interstage WG is sprung for around a PR of 2? Just the thrust load with the increased airmass is too much.
Got maybe 10k out of the old bearings in the turbo, haven't checked on the new set yet, but they've got about another 10k on them. Got a VF27 on the shelf, just gotta get it jammed on there, after the insight swap is running... Ugh, projects.

If you wanna upgrade to a GTD2060VZ, it will require quite a bit of customization to make it work on a 1.9L TDI.

I will soon use a gtd1756vrk on my BKD because I have stock injectors so I don't need bigger turbo, but I think using gtd1756vrk with sotck manifold is not good, actualy I use gtb1756vk mfs, before I was using it with stock manifold and now with 4 in 1 tubular manifold and there is a big difference at low rpm, now no surge and spool realy quikly.


I realy think that my old gtb1756vk with tubular manifold is better than gtd1756vrk with stock manifold. stock manifold has realy bad flow

Still slightly bigger than the BMW's 36mm, so that's good. Can't yet tell from pictures online whether it is integrated with the exhaust manifold or separate.

Yes same wheel size for 210 version, only difference is the rpm sensor.
This unit does 3200 mbar on a stock 2143cc engine, quite amazing for a turbo of this size.
I will test this turbo with a GTD2056vzk comp wheel soon. Let's see if we can reach 3400 mbar...
