Hello everyone - First time posting on here.

I currently own a 2016 A3 2.0 TDI saloon with the EA288 engine, its the 150 version which has the turbocharger with the p/n; 04L253010B

Ive noticed a few people say they've fitted the "190 turbo" but ive not seen much information about it and if its truely a straight swap, although where i live its classed as the 184 turbocharger (GTD1449Vz)

I had enquired with a company a while ago, who said the turbo is slightly different - mainly just the actuator, so im just wondering if its a case of swapping the actuator round from the original turbo to this one? or if its plug and play with modification to the actuator, im in the u.k so as far as im aware the turbo inlet pipes are the exact same (5Q0 129 635), although the goal is to go with a hybrid gtd1449vz -and with any luck, getting close to 240-250 bhp will be a possibility.

Ive also been creating/testing some 3d prints of some custom parts to allow me to run a 2.25" (57mm i.d) pipe all the way from from the turbo to the charge-cooler utilising the O.E flanges, this has been in planning for the last month, and im just waiting for the parts to be machined before doing all the piping, i have tested neuspeeds 46mm turbo outlet pipe, which did make a noticeable difference - but i still think the original charge piping still tapers down too much (as much as down to 42mm, even when the outlet pipe changed for the nuespeed).

Pic here (if it shows up);


My next project which is currently being designed is creating a 3" turbo intake from the maf to the turbo (obviously tapering into the 52mm turbine housing), Im not convinced its going to do a huge deal of difference (if any atall) but theres not much options available - and if i dont try it then it will be sat in my mind if theres any difference to be had :eek:

PN is on the picture quoted in the above post.

Contrary to that post, though, CR190 is distinct from CR184 (code CUNA), and the Borg Warner BV43D of the former is of a bigger frame size than the GTD1449VZ of the latter.

The photos I've seen of examples for sale on ebay are that the exhaust manifold is integrated to the turbine housing. It should bolt up to your EA288 head (check to be sure, the earlier CR TDIs are EA189), but may not match up at the turbine outlet flange.

I have a gtd1449vz hybrid and silencer from xman on my 2015 golf crua. I also bought a cr190 intake pipe. Went on no problem, and I returned the cr190 intake pipe as the stocker works just fine.

Spoke to XMAN and Owain at Malone last night. Both recommend going with GTD1449VZ for drop-in replacement on my 2015 A3 TDI (CRUA). It's a hybrid charger, 56mm 6 blade billet compressor wheel.

What have you found out? Im looking for a turbo outlet for my car before remaping the software. Is there a big difference without the silencer and the Neuspeed pipe?

As even a BONE STOCK 184hp CR CUNA hits the EGT limiter on WOT, you will not be able to get anywhere near 240 or 250 hp with this turbo.

The turbo is limited by its TURBINE flow, so adding a bigger compressor wheel to this tiny GT14 turbine is just a rape of the overall turbo efficiency without any benefits.

As Peppe mentioned Darkside Developments, look them up on youtube, they did quite some r&d with real world numbers what can be achieved with the GTD1449V turbo. (Even though they also might have had to up the EGT limit to get a noticeable power gain)

I dont get this craziness with these tiny turbos to get hybridized…they are already struggling to make the rated power straight from the factory ! Get a man sized turbo and start bragging about it !!!

As adamss24 and majesty78 have stated, the GT14 is turbine flow limited and no hybridization will get you to the desired 240-250 HP with any good results. Even a GTD1752VRK, which I like a lot, will be too small to be optimal for this power range, and you'll want to start looking at the GTx2056, where x=D being preferred, or a GTB2056VKLR.

I think the rationale for wanting to push the GTD1449VZ over the bleeding edge is because that's what comes originally equipped from the factory, so to be able to retain some modicum of bolt-on ability. Honestly, it's laziness and wanting to have your cake and eat it, too. Sorry, but when you want to play with increasing the power >50% over stock, you should expect to throw the fantasy of bolt-ons out the window or temper your target HP - otherwise, do some homework, be willing/prepared for some custom work and fabrication (or pay someone who knows what he's doing the big money to do it).

The main problem is the endless flood of HOAX "Tuner" numbers floating around since "ever", which results in a complete distortion of customers expectance and to be honest in many cases it's a fraud.

But: Where's no prosecutor, there's no judge....

Generally, if we don't make it, then its not worth making and these sort of hybrids are one such product!

Most tuners ignore the EGT's or disable/trick them and the customer deals with the consequences.

The GTD1752VRK is a very good turbo, but not if you only want a dyno figure, its a very good daily turbo.

I have an Xman GTC1556VZ hybrid turbo billet wheel (running 2.1 bar), S3 alloy intercooler, darkside turbo outlet damper, EGR deleted, inlet manifold cleaned, full custom 2.5 inch turbo back straight through exhaust & remapped to 240bhp.
Great daily driver & boosting from 1,700rpm until 4,500rpm.
Also the CR170 standard fueling system tops out at 245bhp so unless ur planning on the very expensive upgrade of CP3 fuel pump & upgraded injectors then there is no point in going for a laggy GTB2260VK turbo or something which wouldnt hit good boost until over 2,500rpm.

Even if you list up your mods 3 times, it does not make the tiny GTC15 turbine bigger or higher flowing.

You can get a stock GTC15 into boost creep with the stock 49mm compressor, so adding a big 56mm compressor does massivly amplify the boost creep tendencies.

It's just a stupid thing to do, no matter who is the supplier, and no matter if you have a hyper mega super FMIC, exhaust or whatnot.

The bottleneck is the turbine.

And to date I have not once seen any logs with reasonable higher airmass from any of those "hybrid"turbo setups than can be realized with a stock turbo.

1752vrk got me 190whp/330tq, I probably could have gotten a bit more with upgraded injectors but as darkside proved the silly cylinder head flow limits the fun on these CRUA/CUNA versions of the EA288 and EGTs limiters will be hit no matter what. The CR190 would have likely not been much of a compromise for the money at that particular time though.
Injector upgrades aren't cheap, but are needed on the CRUA at least to get to the max power which is likely around 240whp with right sized turbo. CUNA has larger units already which is a big $aver. I ended up going down a rabbit hole with my car, hopefully others can learn from it though!

To answer your basic questions:

The 184hp turbo will fit plug and play, actuator has same electric connector.

The actuator calibration is a bit different, but no need to worry, after installation use VCDS to calibrate the actuator to the ECU - done.

However, dont waste money for hybrid on this GTD14, as already been stated above.

Hi all. Any uodate on this? I have a CR150 and Im looking to get to 220hp. Will a standard GTD1449VZ do this power?

The actuator of GTC1549VZ can be calibrated on previos CR engines (ex CAHA), which have BV43a? I'm thinking to replace BV43a with GTC1549VZ. In software I didn't found a calibration map for actuator sensor.

I believe it is "adaptation of turbocharger" in the adaptation menus and to be done with car at idle. Should hear the exhaust note change as actuator is moved from full closed to full open positions.

According to DS website info. If EA288 injectors are only good to support 260hp and they suggest a 2260 for upwards of 300hp (I know CP3 and injectors are needed to get there). What would a 2056 with stock injectors and an Xman CP3 upgrade get me on a US spec EA288 in a '15 Passat?
Edit: or even a 2060?

There are different part numbers for EA288 injectors. CRUA flow much less than GTD (210hp vs 360hp), would bet the CVCA are similar to CRUA. And 280hp is all these cylinder heads will allow. No need for 2260. 2056 or 2060 would be good size. S&S Diesel can upgrade your stock injectors for 1100usd.

Yeah, I was seriously considering one of the "smaller" turbos as an upgrade. Thanks!

PS, didn't you go with a bigger turbo than the 2260? Are you using a 240hp biturbo UK 2.0L (with a single turbo) for the better head flow?
