Turbo Not Spooling

[sogeCEO]

hi guy as the tittle states i've lost pressure some where and the turbo no longer spool's.

"The back story" The car when bought was standard 138xxx's, just 3 days ago I decided to add a FMIC and BOV.

I dont know if these additions have actually helped to send it on it's way, but straight after the FMIC was added, driving it away i lost all pressure but then came back

2-3 minutes later and was back to normal, the next day after starting the car and driving away the turbo made a strange whistling sound while spooling under load

but when free reving in neutral nothing this sound lasted for another 2-3 minutes but the went away and all was normal.

Last night when i started the car and started my driving the whistling sound grew louder and turned into a slight siren like sound, the car still spooled but would not go into

positive on the boost gauge, it would struggle all the way to 0 and still set the BOV off but the higher i rev the louder the sound got.

This was happening right from 0RPM till 2500-3000RPM which is about when i changed gears, then my mate fxxxed it trying to force it into positive on the boost gauge

and thats when all pressure was lost, now the car just feels like it an NA, the car's standard boost gauge for some reason still says that the turbo is spooling and building

it up to the mid point which is 0 but is this only cause of the air passing through the airfilter?

Can anyone please help as i dont know JACK!! about mechanics as for the car its a

Series 2 R33 GTS-T with the new additions aside its still got the stock ECU, should i have replaced it before adding these item or atleast remapped the standard one?

Someone told me i blew a seal in the turbo "on the inside" i dont know if this is true, another told me a compression leak.

Did i just blow mine up? Could i rebuild a busted turbo or should i just buy a new one

Man i dont know but i really appreciate all of those who take the time to read and reply

Cheers

what did you hook the waste gate lin eup to .

sounds like a massive dose of fail to research

[sogeCEO]

FMIC was all install at a workshop as I dont have the knowledge to install myself so it couldn't have been to my own fault as for the BOV "HKS SSQV" i got my mate

who's a mechanic to install.

Have you set up the BOV correctly? If it's whistling, then maybe you are simply pumping any boost straight out of the BOV. Put the original back on!

And have you checked ALL the intercooler plumbing joints?

[sogeCEO]

ok just came back from the mechanics and my turbo has actually seized up and the fan hitting the interior housing, can the turbo still be saved by rebuilding or would

a new one be in order?

[nuclear_skyline]

Hi-flow the standard turbo if possible. Good results to be had there. It depends on how stuffed your housing is though...

[sogeCEO]

Called GCG yesterday and explained the problem to them and said that it was no problem so i guess Hi flowing/Re-building is what im going to do.

As for the housiung i hope its not to bad.

[mad082]

the housing shouldn't be a problem because when they rebuild it they machine out the housing to fit in bigger internals, so any scratches, etc will be long gone.

ahhh i see now why he wasn't so worried when i told him, thnx for that mad
