Go at mappers witch took the turbo with it , it's a turbonetics t4 roller bearing
External gated item any one know of a turbo of the same , this one good for
600 + . It's at s turbo place but they saying its mashed to bits . So I'm after something Asap it's on a v band exhaust side .and kind of why my plate says

likewise, brand new GTK550 here, or a friend has a GT4094R, but that's maybe a bit big.
Although autocorrect turned off would make the post easier to understand !
if it is actually a Turbonetics unit...how old is it ? They have some pretty good warranties ?

Hi Andy I have one big ask here as you have such a big turbo on your focos . Have your Pistons been machined to a lower compression and if so wot to ?
It's just a bit funny your car has done over 600 miles with that turbo on it . It goes on the rollers and it goes so wrong and I can not for the life of me see how the injectors could take out the turbo . From wot I no if your head is standerd and your Pistons are standerd then your turbo will have a lot of back presher hitting it . and it will put the turbo under a lot of strane big time

For reference,
The engine arrived with a random missfire that came and went at idle.
While we were wiring up his Dash 2 coolant, rpm and wheel speed sensors we obviously had the engine running and the missfire got worse and worse and we found it was fouling No:4 plug. Upon investigation we discovered number 4 injector has an intermittent dead short which is causing it to stick open and miss close events from the ECU thus causing overfuelling on Cyl4.
The engine / turbo also smokes when it gets very hot which is indicative of a failing turbine oil seal.
Because of the above two items, along with a few other issues like a leaking fuel rail the engine was never driven out of the estate, nor did it ever make the dyno for mapping to even be started.
I fail to see how the injector sticking open with the engine only ever idling has caused the turbo to be "mashed to bits" I would challenge that diagnosis with whoever has made it pal.
Fuel in the exhaust housing cannot destroy a turbochargers core as the oil pressure is higher than the turbine inlet pressure... The only way it could is if it ended up in the sump and heavily diluted the oil which it didnt as we checked oil level when we discovered the problem and it was fine.
I guess if you have run it like that for a long time with a lot of oil dilution then yeah, maybe you could scorch the bearings, but as it came to me on a trailer I am guessing not?

Odd thing is...there are no oil seals in an oil journal turbo. But it doesnt make any sense a leaky injector could fuck a turbo.
Although what make etc of injectors were they ? such problems are rare
