Default GTB2260VKLR Hybrid

Hi Guys,

Does anyone have any experience of hybridizing the GTB2260VKLR. This would be for a C350 CDI.

I have spoken to a few turbo specialists in the UK such as Turbo Dynamics, Xman and AET and they advise that the most they could do with this is a bigger compressor wheel.

Is there any scope to add a bigger turbine as well?
Thanks

Why do you need it bigger? It's already plenty for a 1.9 or 2.0 unless you're going with a compound setup.

Because why not? Its normal that basic chip is not enough after some time and you wanna make more power. Some basic 300hp is really not that much such a heavy cars. Not sure if there is bigger wheels available for vklr.

The car in question is running a 3.0L V6 (OM642) currently 310bhp with just software. I have a friend with an E90 BMW 335D stage 2 that i would like to keep up with to answer your question

Im really just looking for experiences anyone has on upgrading the GTB2260VKLR and how they found it and any expectations on what power increase a bigger comp wheel would give over the standard unit.

Thanks

I'm already considering going from 2566vk to GTD2872vkr On a 4 pot. The quest for stupid power never ends.

It may be worth you taking to Craig at TDI Turbo's in the UK, he is ex Turbo Dynamics.
I had a VW T5 2.5 GT2056V machined to take a Mercedes GTB2060 turbine and comp wheel.

Talk to Majesty here, i think he has a solution for the VKLR , should be enough for 380-400hp
Under 3000rpm will be dead of course, not much fun for a street car.

Change only the comp.wheel and you can push it to 350hp max also. Larger turbine would be ideal ofcourse. There is option to go gtb2056 as base from v6 320cdi and use amg turbine and some larger compressor. This would give you potential for 400hp. It would be pnp but slower to spool as its not bb turbo.

Thanks all

From reading up it would seem to keep the drive ability and to keep the potential for lag down then an upgrade to the comp wheel to something reasonable would be enough for what im looking for (along with supporting mods)

Its interesting to see the page from KC performance, looks like they have fitted a 70mm comp wheel to create to the GTB2270VKLR, i wonder how the lag would be with that size of wheel....i was only thinking of going GTB2265VKLR

From what I read you want to keep the compressor inducer the same size as the exducer turbine roughly, what goes in must come out, I don't no if the amg gt23 turbine fits the vklr as it's ball bearing but its 48.6mm exducer so a compressor wheel around 48mm inducer would be a nice match

There are lighter options for AMG TW that go with BB.
70mm cw on stock vklr turbo makes no sense.
