Help Please On 32 Gtr Engine Or Turbos

[foney]

I have read 90% of all posts and have found nothing that matches,

Background,

Last week i recieved a bad batch of fuel, car ran ruff and got to a point where it didnt start, lots of smoke.

I did a complete drain of the tank, pulled out the fuel pump, flushed the fuel lines and the fuel filter then cranked it over a few times to clear any remainng fuel.. put in about 20lts of fresh BP ulitimate as i mannaged to get it running again like normal with boost. Drove to station and got some injector cleaner and drove aroun for 10 minutes, seemed to run ok but kinda still a lil ruff paked it up and left it for the night,

The next day i tried to start it again and it now runs again like it did before with the bad fuel, ruff idle lots of black smoke, tried to take it for a drive no luck.

stalls and runns ruff and i also then found a noise comming from the intake pipe from the rear turbo, comming out of the airflow meter loude wistle/sucking noise after a lil throttle, massive smell of fumes etc. I had the pods off at this stage.

I have newly installed Z32s as well,

Im thinking i have F ucked the rear turbo, dunno how, or its a pipe which ive inspected everywhere..

If the turbo was gone then it would still idle corect?

Im lost and alil upset, Cheers guys any help would be good.

The symptoms you have described do not sound like a blown turbo.

What ECU are you running with the Z32 AFM's?

[R.3.2.G.T.R]

i was thinking un-tuned ecu for the bigger afm, but his signature states pfc, double check your afm plugs

computer is power FC, will recheck connections to the z32s, however the voltage is all running good and no probs with them on the hand controller were displayed.

umm maybe turbo oil seal has gone, however i remember when my rear turbo zorst wheel let go, i didnt have any hunting, idling etc issues, only boost would get +ve boost.. i assume you didnt hear it go bang.. perhaps check cat for remains of rear exhaust wheel to confirm..

yea, im in the process of ripping the old turbos off to do a better inspection,

Youre not making alot of sense.

When you say running rough, is it a rich rough or a missing rough?

White? Blue? Black smoke?

If you make these clear we can help diagnose.

You will always have a little bit of oil in your rear turbo, thats where all your blow-by goes so its not necessarily blown.
