Blown turbo on a new stock JDM Evo 9! Help!

[sjaved]

Sadly I start off my posts with a bad news:

The turbo on my new JDM Evo 9 GSR failed horribly (Picture included).

Can anyone help me what the reason could be for this catastrophic failure? My car is totally stock with only 6900 Km on the ODO.

What do I need to do or should do before I install a new turbo so that this doesnt happen again? Could the broken metal chips have gotten inside the engine? If so how should I clean them?

I saw oil inside the piping up to tje intercooler intake piping as well. But not on the other side of the intercooler. Could this mean trouble?

Lastly, will my car ever be like before?

Thanks everyone.

Bloody hell mate :shock: That is terrible, and so little mileage too.

Something hard has gone through that :shock: :shock: :shock: :shock: Debris in your pipe somehow :???:

I'm so sorry to hear your bad news Hope you get a new one sorted soon

Do you know if it was one of the weak IX mag units? I know there were alot of early IX failures and the turbo was changed on later production models.

I can't recall any more than that at the moment, but i'll have a quick dig around.

I've had a quick look, the suspect units that had the compressor wheel failure had part no. 49378-01570. Mitsi did swap them on models in production but there wasn't a recall i'm aware of. The replacement part is 49378-01571 TD05HRS-16G6mC-10.5T.

Don't know if that's much help to you or not, but a pm to Madmat may well help, he knows a lot more about these units than i do.

YEP! 49378-01570--this is the number on my blown unit as well. It was one of the first lot of evo 9s released in Japan. So I guess I just received a bad unit. Mitsu in Japan said that it was not a recall item either.

Will this blown turbo affect my engine or damage other parts? What else do I need to do before I install a new turbo?

That's it i'm afraid.

You'll need to know where the bits from the compressor wheel have gone, so it's pipework, intercooler, and maybe beyond? I'd guess that if the intercooler isn't badly damaged it would catch most of the bits, but i'd check with someone who knows more.

Have a look and see what got to your intercooler, keep all the bits and see what you've got? If shards have got to the intake values they could be damaged and potentially the cylinders scored. If you shut the engine down quickly you may have been lucky. Fingers crossed it's not so bad for you.

Good luck and i hope nothing travelled too far.

The metal shreddings shouldn't get past the inercooler, right?
I found two large pieces of metal stuck in the intake side inside the intercooler. Also flushed out some more very small pieces and some dust particles as well from the intercooler. Do I need to replace the intercooler as well?

Is there any way I can know if any metal parts got through the intercooler. If it helps: The car stopped boosting after this turbo failure, there was ZERO boost, and I couldn't go higher than 3K rpm in each gear while driving. While standing still, I could free rev it very high. The car idled fine, with no smoke out of the exhaust. Just a whining sound when pushing the accelerator.

thanks a lot.

I can't really help you any more, i do know that on occassion when turbos have failed bits have reached the pistons. But if it's running fine you may have been lucky. If the intercooler isn't badly damaged, and you've flushed it very throughly wouldn't have thought it needs replacing.

Hopefully some of the more experienced guys who've stripped down after a failed turbo will be on tomorrow and help out with some advice.

Sorry to hear of your predicament
There is actually a third revision of this unit after some more failures at motorsport level and a few road cars in the mix! (Mainly due to anti lag)
Mitsubishi are a bunch of lying cocks, they still deny that there is no known fault on the GT unit yet there has been three revisions- some ones telling porkies
All i can suggest is to replace your intercoooler for a new item (Good time to upgrade if your looking at future mods), remove all intercooler hoses and clean thoroughly. Clean your intake pipe, replace your air filter, oil and oil filter. Do a visual inspection of your intake manifold for debris.
Check and flush through your turbo oil feed and and return lines. You should be ok.
