There is something wrong with information about GTD2355VZ, because I cant find that turbo and seatching using turbo part Code I found GTD1244VZ, what is more real, if it comes on 1.6 engine with 120hp.

Hello Guys,

I am new to this forum

Really amazed to see the amount of information being dumped here

I own a 1.6 tdi skoda rapid and has plans for turbo upgrade along with an intercooler and exhaust

Currently stuck with two options for turbo

a) GTC1549VZ
b) GTD1752VRK

Some threads metion that GTC1549VZ is best suited for 1.6 while some others argue that GTD1752VRK would be better

I got a chance to drive another rapid fitted with GTC1549VZ and was really amazed by the pull but found that the turbo kicks in only after 2500 rpm !

I am not sure whether GTD1752VRK will have a similar behaviour though the specs mentions about lower lags

Plan is to have 200+ bhp and 400+ nm of torque

Expecting suggestions/comments from experts

I've been debating whether or not I should replace my VNT-17/22 with a GTD1752vrk ever since I learned about the turbo. I know it's an improvement over the old 17/22, but how much?

Then I found these hybrid GTD1756vrk & GTD1760vrk turbos and was thinking that they would give me the larger bump in performance that I'm after.

What do you guys think?

Define your power goals and then we can go the minutiae of wheel sizes and types. But in general, I take a dim view of wheel sizes >= 56mm for a 1.9 TDI on account of surge limit unless specifically warranted by your build objectives. The OEM GTD1752VRK is installed in a 190 HP engine out of the factory and has headroom to support ~230 HP, so unless you're going to be making more than this, it is only wasting money and putting your engine more at risk of operating in compressor surge conditions at low-RPM/high-boost conditions. Besides, when you start going to the ~250 HP range and above, you should be looking at upsizing the turbine frame size anyway (with, of course, the attendant compromise to transient response). Edit: That leaves a narrow range of power 230 < HP < 250 were there is a gray area to look at alternative compressor wheels, and I personally would prefer to work completely away from this grey area and employ highly engineered OEM solutions instead of being sold to aftermarket spin for "Gen XX super-ultra-hyper-awesomeness billet expensivium" wheels.

I knew I should have posted what engine mods I have done on my BEW(PD100)
VNT-17/22 Turbo
Whitbread 2.5" to 3" Custom exhaust with Aeroturbine muffler
Forge PD130 FMIC
PD150 Intake Manifold with Race pipe
PD150 Turbo Inlet Pipe, R32 MAF and Airbox with R32 DSG snorkel
4 Bar MAP sensor
PD150 injectors and head bolts.

My goal would be to keep the response I have now with the 17/22 all while gain power throughout the rest of the rev range till red line. My car currently makes ~ 190whp and my thought process was that with the GTD1752vrk and R783 nozzles that I would be in the 210-220 whp range.

The reason I asked about the GTD hybrids was to see if they would allow the car to make an extra 10-20 hp over the OEM configuration. The problem that I worry about is that I still have stock internals in my BEW, but it's no longer a daily driver(if that matters...)

I personally would leave the GTD1752VRK as it is.
Although 210-220 "W"hp will be a tad to much IMHO.
