Blown Turbo.

[mazgtr]

Can someone please explain the symptoms of a blown turbo to me?

Ive got a loud rattle that sounds like its coming from one of my HKS turbos, it makes the sound at idle, and it doesnt rise with the revs. My GTR is also down on boost, 0.6bar instead of 1.2bar.

Could a blown CAT cause the rattle and increase backpressure to rob psi?

Thanks, just a bit nervous...

If there is a rattle, stop driving it.

Then check the turbos, see if there is play or not, you'll soon see when you rip the piping off generally as the housing/wheel will have met each other and made a little etching

might be a blown gasket aswell..

[Devils_Advocate21]

Gremlins?

Could be the bearings

[race_snooze]

if it doesnt rise with the revs??? more then likely something loose.

Well CRD have just called me and they think one of my HKS 2540 turbos is blown....

I dont really know what to do or where to look.

CRD beleive that a repair kit for the turbo's no longer exists, although they said they'll call around for me.

I want to try and get out of this as cheaply as possible.

Powerwise, im not really bothered. But 280KW to 350KW AWKW would be the ballpark.

UAS sell Garrett N1's for $3100. The GT-SS's are up around the $4500 mark, thats more than i can afford.

Does anyone please have any advise or places i should call?

Im really stressed out at the moment and quite upset.

Any advise would be great...

Thanks

gcg might be able to rebuild them for you, depends on whats "failed"

could be bearings, the wheels, the shaft and so on...

find out whats busted and speak to gcg in sydney, they should be able to give you a price.

if its unfixable then gt-ss's are probably suitable, you can sell one of your work 2540's for some cash so its not as bad. i dont think gt-ss's are $4500 though, i think the UAS pricing is a little "high"

GCG should be able to rebuild your 2540. it may be worth considering rebuilding both at the same time. also make sure you get them to try and find out why it failed in the first place. faulty oil drain? oil feed? something else?? make sure it doesn't happen again.

[Tangles]

talk to Slide here on the forums about rebuilding both ?

ive got the same thing now on my r33 gtst... but with mine the ticking noise increases as the revs increase. I only revved it to like 1500 to test it out though..

Also there was also a small piece of this black plasticy stuff in the throttlebody, wedged between the butterfly thingy.

Im getting it checked out on monday hopefully, but does that sound like it might be the turbo aswell ??? or the bearing or something ??

also the noise doesnt seem to change in volume. I'll take off the afm pipe and see if the turbo looks screwed up.

[justin911]

took the afm pipe off... hehe the wheel thingy is completly stuffed, theres like chunks missing and bits all over the place..

what would make the ol girl die and how bad is it if parts of it got into the engine ??

[Cubes]

Its quite possible the exh. wheel let go as a result killing the turbo's bearings (unbalanced) causing the comp. wheel to slam in to the comp. housing and breaking. Then it goes through your motor.

Similiar happens when the comp wheel is metal apart from instead of having the plastic go through your motor you have shavings of metal.

well like i was saying there was a bit of the plastic stuck in the throttle body between the butterfly, causing it stay open when i was idling. It was realy small though. There was one other small piece in that metal pipe that connects to the throttle body. But besides those 2 litle pieces i couldnt see any else. Would most of it be stuck in the intercooler or something ??

I probs should of mentioned i was at the sauvic drag day 2day and it happened when i changed from 2nd to 3rd gear at like 6500rpm, then the boost was all gone :~(

but ya what happens if the plastic crap gets into the motor like it might have ???

if its not bad for it, i'll just slap a new turbo on... but it doesnt sound like its gonna be good for it

GT-SS are not $4500 landed mate

I paid $3300, and there are others who have paid ~$400 less than me since then

Um i woudnt be driving your car anywhere, plastic in the butterfly and goin into the enigne is very very bad......i would either start ripping the engine apart now or......slap a new turbo on there and drive it till it dies ......

[justin911]

hmmm so u rekon when i take my car to the mechanic to get em to check out the engine they will need to need to take the engine out of the car to have a look damage ??

simplest way - take out the spark plugs. look inside. if you can see anything in there, your engine is most likely gone.

plastic or metal, doesnt' matter. That plastic isn't like condom rubber or something. it's very hard heavy duty plastic. think about how strong it is to withstand the high RPM.

Basiaclly, it woulda smashed into a powder, probably scored the bores too.

Dump the engine oil and run it thorugh coffee paper.

you shouldn't have drive your car at all. I woulda turned it straight off.

Engine is probably dead now.
