Hello, I ask you for help. What the difference is in the turbine GTD2060VZ and GTD2060VZK ? I bought GTD2060VZK number 059145873AJ? Is this the same turbine at GTD2060VZ 059145873BB or BC ??

If Im not mistaken, I believe the only significant difference is the VZK has both it's oil supply and drain located on the same side of it's CHRA and the VZ has the more traditional top supply, bottom drain.

Hi everyone!

I am getting my hands on a new gt2052v turbo from a t4 transporter, the question is about the fitment in my mk4 golf 1.9tdi. I will know hot to reclock it, but will be there enough space to weld a flange on the old header so it fits there and does the job?!
The thing is I haven't measured anything when I pulled the engine out and now I can't get to my car for a while(Because I am working foreign) so could anyone help me out with some tips and hints about fitting that turbo on a stock header(cutting off the old turbo). Cheers!

I have a pd100 brm in the US. I have a blown 1646 (pd140) turbo with good housings. This turbo was only available in Europe, and is expensive here. I've heard the new passat cr140 uses a 1646 variant, and the jetta uses a 1749 in the US. These are much more readily available here. Do any of you know what it would take to fit a cartridge from either of these into my housings? I can make the actuator work. Any suggestions or thoughts on performance expectations? I'm running the colt stage 2 cam with a kerma tune.

GT1646 from PD140 is GTB series turbo. What you call "1749 from jetta" is most probably gt1749va from mk4 generation 1.9tdi. If so, then CHRAs between these two are not exchangeable - different generations, different VNT designs, different turbine housings etc.
Get yourself GT1749VC (which is also GTB series) from 2.0tdi PD170 (engine code BMN) and then swap exhaust housings

Hi nin,

Thank you for the response. The Cartridge replacements I found were from CR140 cars. From what i found, the Jetta and Golf MK6 with CBEA or CJAA have a GTB1749 with smart actuator. The passat (NMS, US version) has a CKRA with GTB1646 (also smart actuator). I can purchase a cartridge for either of these very reasonably. I was considering doing that and using the stock actuator from by GTB1646 from PD140. It sounds like this is very possible from your post.

nin2 · Sep 2, 2015

Sorry, I'm not familiar with CBEA and CJAA, but quick googling makes me think they have Borg Warner turbos...

None of this is correct, they use BW BV series turbos.

NTX_TDI · Sep 4, 2015

Thank you for your help. I'll keep looking for a compatible CHRA. I know a GTB1749 will fit in the manifold (turbine side) from reading here. Can I reuse my compressor housing from the 1646 with the 1749 compressor wheel?

Thank you!

nin2 · Sep 8, 2015

Sure, why not.

majesty78 · Sep 9, 2015

If you machine it to fit the 49mm wheel, then yes.

Hi. what do you think? what will be today the best replacement for GTB2260VK? My 2years old vk unfortunatly died on our 300HP setup with 2,4 boost and 950egt

maybe extended tip bilett wheel GTB2060vklr?
or GTB2260vklr?
or extended tip bilett wheel GTB2262vklr?

or try to use GTD2060vz? (thats my favorite now

i hope ist not to big spam question

Take steps to reduce the EGT first, then ask the question again, or else you'll just kill any new turbo also regardless of what it is.

majesty78 · Sep 14, 2015

I have to 2nd this what Dave wrote.

With 950 celcius sustained you will kill any VNT turbo sooner or later....

As 300hp are not so very much, I guess injection timing is not in optimal window....

gabrielT · Sep 14, 2015

yes im working on reducing egt, but i think last emprovement will be bigger valves because i have ported head and 260° dbilas camshaft
i dont no other HW upgrade for reduce emp
it is ve engine with 12mm pump and firad 120% nozzles, fmic etc..

that is reason why im put modified GTB2262 on my list because encrease the boost will help also i think...if not we need to reduce fuel...i know...

edit: 950°C is the top of egt...it means 5th gear ful throttle from 100-to 240km/h

thank you for help!

IonutTurbo · Sep 17, 2015

Hello ,
Dose anybody can help me whit the meaning af hella actuator code ?
I am wondering if the red marked zone can make any diference in functionality as log as garrett code and hella code are the same.
Thanks in advance for your help.

JFettig · Sep 17, 2015

Probably just the mold cavity marking

Shortydap1mp · Oct 29, 2015

I would like to know what software I would need to tune myself?

Rub87 · Nov 2, 2015

software won't be the biggest issue I think

IonutTurbo said:
Yes is already available , i will have it this month , i will be back with infos about measurement of turbine and compressor wheel also obout the ball bearing.

Is this the bmw unit which you offered for sale some time ago? let me knwo if the price has dropped in the meantime

and offcourse would be nice if you could post wheel dimensions

Rub87 · Nov 11, 2015

Quite small comp inducer, that will be killer low/mid end turbo.

need although 40mm comp inducer wheel with ETT

is not a problem to mount a 42mm / 56mm

i am curious about the cw 8+0 blades , i hope i have time to make a test like ...
36 mm / 52mm 8+0 blades VS 38mm / 52mm 6+6 blades

[486] · Nov 11, 2015

I did some quick googling a bit back and from what I've read the "GTX style" compressors are quieter, maybe spool a little quicker, and based more in the low end of flow, where the 6+6 wheels flow more but are louder.

Somewhat interested in how it does. Got an old GT1752 with similar wheel dimensions I've stuck into a VNT turbine housing I've been talking about putting in for a while now.

loudspl · Nov 13, 2015

GTX-style wheel supposedly better for our high PR engines, faster spool

6+6 is better flow, but spool can take its time!

That GTD1752 w/ billet ~40mm wheel would make a killer daily driver

hatemi · Nov 15, 2015

If thats the turbo thats on a F series X20D engines, it is supposedly good for 220-240hp...

On a CR, less on a VE or PD.

Why would that be?

diffas · Nov 16, 2015

Better afr on cr engines

Rub87 · Nov 16, 2015

that not really 100% true, a 16v PD will have similar FSN at equal lambda and slightly better bsfc than a CR engine.

Honeywell Unveils First Boosting Application with Two Variable Geometry Turbochargers in One Unit

Honeywell’s VNT technology uses a row of pivoting vanes that move to continuously match the turbine flow capacity to the actual exhaust flow and drive the compressor to deliver the exact boost requirements that the engine needs. The development of a TwoStage Series Sequential system, using VNT turbochargers for both the high pressure and low pressure stages, demand strong competencies in performance modeling, aerodynamics, heat transfer, material science, mechatronics and control. Together these sciences and system design deliver exceptional low end torque, transient and steady-state performance at class leading fuel economy and meet the stringent CO2 targets of Euro 6.2 regulations when coupled to a modern after treatment system.

Honeywell is using two different size VNT turbos in its most recent TwoStage system for the new BMW 4-cylinder diesel engine in the 125d, X1 2.5d and 225d. In this application, two variable geometry turbos are located above and below the exhaust manifold. The smaller high-pressure turbo is mounted on top and larger low-pressure turbo below. The combination creates new levels of responsiveness at all speeds and helps the engine perform more efficiently to improve mileage and emission control.

For those who love the GTB1756VK, I hope this makes life a little bit easier; especially for tuners.
VAG ECU PN 4F2 910 401R belongs to the Audi A6 2.7L TDI. Now, parts gurus who know more than me, please verify that this ECU belongs to the right Audi A6 that had the GTB1756VK on it.

Assuming the engines have the same VE, we can easily convert one map to the other. A 2.7l engine moves more air at 1000 RPM than a 1.9l, or precisely by a factor of 2.7/1.9 ~= 1.421. Multiply all stock RPM axis values by that factor and you get a 1.9l map, effectively. I took a little creative license to interpolate ~1/3rd of the map below since there were some holes due to the lack of 'resolution' of the boost map after being scaled.
