Options on Turbo Upgrade

[NZVDUB]

Hi, I’m fully deleted, stage 2 TVS Tune (185hp) muffler removed, 68000kms and looking to upgrade my turbo.
Was undecided whether to go with XMan hybrid 1456 or bigger 2060.
It’s my daily driver and ideally looking to get up to 250hp.
I’d have to upgrade the Maf sensor to 4bar for the Xman 1456 turbo and could do the same for the 2060 but if I wanted more power then id have to get injectors and a CP4 fuel pump which I don’t want to do because of cost.
I’m in a pickle or procrastination on which turbo to get ha ha

what do you guys recommend?
is an 30-50hp worth all the costs?
will it good for a daily driver / racer?

GTD1456 will be far more economical as far as install goes..much more plug and play with the intake, exhaust, and oil lines.
I don't think it will get to 250hp though, it's still a tiny turbine but would work well with stock pump/injectors. You might be able to turn up the rail pressure to 2100bar and get them slightly above 210hp, but not sure by how much.
Also, stock MAP sensor on these is already 4100mbar..no need to change.

Spoke with Xman and they did say the gtd1456vz would be an easy bolt on and with the 4bar maf sensor I could get to 240hp by upping the boost

Well, your car should have 4bar sensor already from factory, but I doubt that turbo will last very long at 3bar boost request. And the fueling is what will limit you, not the boost.
It's a worthy upgrade still for the ease of install, but I would keep expectations a little lower.

@Xtremefunky I know has tuned some of the CR190 hybrids, would be curious what he thinks.

Every EA288, even as little as the 1.6TDIs have a 2200Bar sensor as well as 4Bar map sensor from stock.
Even more so. The stock sensor measures exactly 4.12Bars and "upgrading" to the ordinary 4Bar map you do on EA189 engines,
is actually a downgrade and doesnt make any sense at all. If anyone recommend you ever to install a 4bar map "upgrade" on EA288,
I would highly recommend to rethink about this guys suggestions.

Anyway. GTD14 doesnt make any sense to upgrade. Since the beginning of EA288 it was never a CW (compressor wheel) limitation.
It was always the exhaust gas temperature. In order to get the temperature lower, you need to do something at the exhaust side and not on the
compressor side. By "upgrading" the compressor wheel, you make matters worse. Generating less power than the stock turbo,
when used with normal EGTs.
If you (or rather said your tuner) dont care too much about EGTs and reliability, you can surely upgrade the CW and benefit from it.

Ok noted on the 4bar map sensor. I'm not that clued up on the car and it's my first diesel

The price to service and upgrade my CW on stock turbo costs the same as buying a new turbo hence why I was going down that route.
Was hoping to get more acceleration from stop-to-start traffic and powerband past 4500rpm.

What i don't want, is to spend the money and not be thrilled with the upgrade. I'd rather save alittle longer and get a bigger turbo, fuel etc and get the most out of Stage 3 upgrades.

OR

I leave it as is and start working on the efficiencies to make it lighter, ride better and cooler air....

OR

Buy a BMW 335D station wagon and tune it to get more power and acceleration

If you want power past 4500rpm, you need a bigger turbine. A GTD2060 or GTD2260 would be all the turbo you would ever need for this motor without being bigger than necessary. I would caution though, that if you've never driven a bigger turbo TDI, that there will be compromise in torque before 2300rpm or so. If you drive mostly in low RPM situations, stick with a CR190..if you don't mind revving or downshifting often, then for sure go larger.
The larger turbos will require different oil feed/return lines, modification of your downpipe flange to match the different turbo flange, modified turbo inlet from the airbox, and slightly modified charge outlet silicone. On the CR150, the oil return port on the block is super high up just underneath the exhaust manifold. A turbo like GTD that is welded to a matching exhaust manifold will make that easier IMO.
