Hey guys,

My turbo spatt the dummy yesterday , what happen was i was in a merging lane, and a truck wouldnt let me through, so its either get stuck behind the truck or get in front of it. Obviously good things come to those who wait... but with my impatients, i dump it into 2nd @ 60-70km/h. Car boosted and heard a loud backfire pop after i back off.

Now the car makes a weird az sucking sound. Its like your normal turbo spool sound but on a rhythm like a WRX burble. No i havent drop a cyclinder. Only makes the sound on boost and comes from turbo not engine or exhaust.

Im not blowing any smoke and the turbo is still boosting ( 10psi then, have now pulled it back to stock )... I've check the front wheel and got no shaft play side to side, but slightly back to front. The front wheel is perfectly fine with no defects.

So my conclusion is , i've done my Bearings over...

So my question is... Lots of people sed if you keep driving a car with a blown turbo your engine will eventually die and will need a rebuild ( something to do with ceramic dust, but i dont think my rear wheel is gone ) ?

Is that tru ? Even if i drive off-boost ??? Its my only daily round about and with uni/work. i need to get around. So is it ok to drive the car as long as its off boost ???

Any help be GREATFUL guys !!!

P.S: Anyone got a Highflow for sale ????

it only damages ur engine if any parts of the turbo drop back into the egine through the exhaust manifold when it blows but as a daily drive stay off boost... drive as lightly as possible and if u have a boost tap, wind it up so no boost is made. thats a safe way to stop doing any damage, but on the other hand this could be the perfect time to get a new turbo?

something ball bearing..

I didnt say it sounds like a WRX ... Read the post properly dude...i sed the sucking sound of the turbo is in a rhythm like a WRX... and its not the engine note or exhaust note, car sounds perfectly fine off boost and wen in neutral reving. Exhaust note is normal even on boost.

Its only when the turbo spools and on boost.. It goes shh shh shh shh shh instead of Shhhhhhhhhhhhhhhhhhhhhh

Plus if the turbo is making boost doesnt mean its fine. You can have warned and f**ked bearings and the car still makes boost... also noticebly less power

Well cant pull the engine apart to check inside, but tappets aint ticking, no oil or blow by, idles fine, no knocking or detonation, revs cleanly in neutral all way to red. And wen you drive the car. Engine feels and sounds completely normal off boost, even wen on boost, car feels normal as in operating normally. Just not as must OOMPH and turbo sounds like shit....

Wen i pulled all the cooler piping off, no oil or any bits in it. Exhaust note is normal. Car doesnt blow any smoke whats so ever.

I've did search and ask few mech friends and they sed turbo bearings are gone...

Although i forgot to mention.. prior to this the last month, the spooling sound has been gettin a louder whine/whistling to it. And feel not as fast as it use to be ( could be because im used to the power ) ... but i always thought it was like gasket leak. But check all mani bolts / turbo flange bolts ect... Its not a Exhaust leak sound. Its definately coming from Intake / spooling sound

Yep check all piping when i pulled it apart to check front turbine wheel... not losing vacumn on boost gauge, car would of stall and idle funny if i had cooler pipe blown off...holds boost fine too ( but i try not to try on boost now )

Turbos generally spin at up to 130,000rpm - any bearing issues will show up very quickly in a seized turbo / blown seals pissing oil everywhere.

Almost sounds like something loose in your intake - is there anything loose in the intake side of your intercooler?

How about loose nuts between the exhaust manifold and the turbo exhaust housing

I have had that on turbo cars where with this being loose, and the gasket flapping around making a pulsing sound...

definately coming from the intake... Cuz if thats the case, the intake sound wouldnt change if its nutz and bolts... The spooling sound/intake is making the noise. Also already checked all nuts and bolts to. just going to undo the cooler pipe on the hot side.. and check if anything is sitting at the cooler core.

If anything went through the Turbine fins would be super screwed...

Heheh but little do you know my avatar... that money was loan money from bank to buy the car... lolzzz... wish i had that dosh.nt

Yeh i really wish i just be patient and let that truck go.. :wub: ... but i guess it would of happen sooner or later.

Car is pulling 201rwkw

Greddy front mount

SAFC2

Full zorst / 3" cat

intake & Cai

Walbro pump

and 10.5psi and spikes to 12-13psi...

I believe the turbo was at its time to go, it is 13years old and i guess the turbo spike doesnt help.

Whats with the the sphincter of the universe slapp ??? i say something wrong, even on load car revs cleanly to red, just flat power like N/A. ( not driving on boost anymore though )

Everyone has diff ways to diagnoise their car, i just figure if the car revs cleanly to red, even in neutral with no load... it would let me know if i drop a piston or dun a valve spring or something as the car would not rev cleanly.

But i aint going get into a forum argument that leads to no where... it doesnt help or fix my probs.. So you can the sphincter of the universe slapp me as much you like

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
