Discussion: Increase turbo pressure [ecm titanium] 2.4 jtdm

leave the gtb2056v , at most put a 2260, 2256 ? a turbine of the old generation. Then I would tell you that you adjust a turbine increased not ? cos? as simple as it seems, will have to be adjusted (to attempt) the whole of the duty cycle of the variable geometry and the corresponding PID controller. do you...

thanks to all for the answers ! the game the axis do not have one, I checked it from the cold side ( as if it were new to the turbo), I spoke to a mechanic and telling him to phone the problem mha said that' match the geometry, also xke' make lots of pressure fluctuations , example : I do a pull in third, starting from 900 rpm to 2000 rpm and pressure to 1.5 then back to 0.7 then immediately rises to 1.4 , and then you hear so much of this 'empty' .
Someone I confirm the compatibility of this turbo [ Garrett VNT-2256 1.8 constants 2.0 peak amended by mdracing, cost 1700 euro] glue for my car ? the type that is selling it says that it is perfectly suitable
Turbo oririnale and' gtb2056v

I usually geometries in the disassemble to clean them and place them don't change a turbo unnecessarily...
maybe they were customers of today is the day that as the year of the troubles go on a full replacement...

do check the geometry, you will often incrustations or very small irregularity? on the surface, where rest the fins in the long run break the turbine... if manutenzionata time it really takes very little to clean up and smooth out the irregularity?.
In theory ? a job that you could be yourself, a lot of good will? and a bit of caution in disassembling the turbine...no ? need to ritararla seen that you're not going to touch the impeller.

Emits some whistle the turbine?

It begins to whistle +smoke after 3000 thousand rpm at full throttle while if I press to the bottom of the gas is not given

B? you could also try to give a clean as whistles only at 3000 rpm, in some cases, when the fins deform the turbo whistles before then pu? also be that it is only a scale.

I say that you have the palette of the geometry, smeared great. Smontale, there are guides on the net, even if I am not of your troubles identical, but basically the system ? what

Yes I also think so, once disassembled, you may clean it with a little bit of gasoline in order to remove any kind of dirt.

confirming that it is a problem of variable geometry you've got it by the fact that after the removal of the dpf problems are increased with dpf most likely be the opening of the blades of the geometry was sufficient to generate the required pressure, in the absence of exhaust back pressure after the removal of the palette should open up more to compensate and may be blocked.
