So, i was at the track this fall and all of a sudden my turbo started whistling and I couldn't figure out why. So, I towed it home and put it in the garage. Well, i decided i needed to find out what to by myself for christmass and I found this......

So, what if any engine damage should I worry about from this type of destruction to the wheel? I am thinking of calling http://www.majesticturbo.com/ or http://turbochargers.com/ to see about getting this slag rebuilt with the 27 side. I am going to do a compression test tomorrow but I honestly am a little nervious that I might not like what I find.

wow that doesnt look good... Any idea what caused it???

Mighty Shilling

Ouch! that's pooey!



I know this happened on Eyal's turbo, and IIRC, nothing major happened to the engine. I'd reccomend an oil change too... but yeah, get that taken care of immediately. do leakdown and compression to find what you're looking for.

The nut for the turbocharger impeller fell off

I've seen that happen on a friends car. Were you getting any appreciable compressor surge?

gandore

I didn't get any surge I knew of but the boost was cutting at aroud 5500 rpm before it started whistling/chewing up the compressor.

Was the turbo ever rebuilt or disassembled at any point?

gandore

I am not sure about the exact history of the turbo.

I'd stay away from Majestic, there were a number of people on this board who complained on their services (smoking turbo's and so on).

Go for Mr. Bob at www.turbo-performance, he charged roughly $650 for rebuilding and a K27 cold side swap. He builds 3-4 of these turbo's weekly, and no complaints on his work.

Your combustion chambers are now contaminated with debris. This may also score the cylinder walls. Unfortunately, this calls for a head-off exam.

WHOA!!!! WHOA!!! WHOA!!!

Hose is soooo far off on his recommendation, four listers have had turbos fail repetedly from Bob. Search my posts, Bob screwed me on three.

Hopefully your IC had enough oil in it to catch most of that, but thats ALOT of shavings. Inspect your intake and maybe even plan on getting a valve job.

Good luck.

Drain your oil, let it settle and look for metal particles at the bottom. The other thing that causes this is airbox screws coming loose and making it into the turbo.

It’s a poor picture but it looks like the nu and part of the shaft are gone!

Typically there is not much damage if any in side the engine - the parts that make it that far a pretty small and at a decent rpm / boost will past right through the combustion chamber. If there were any larger parts they will be in the intercooler – you have to take that out and back flush it – a lot!

If you can find somebody with a flex boroscope have a look down the spark plug holes – a new boroscope is not much more than the cost of the headgasket and seals!

As far as rebuilding – why? You can get a brand new To4e based turbo for about $800 or much better turbos for more$.

ibkevin, sorry on you're bad experience, and i must have missed you're post on the bad turbo, as well as the other rennlisters. From my experience, i had Bob deliver to me 3 turbochargers with different configs, and all worked out fine, even though he was half the world away from me, hence why i recommended him.

hi five for joining the club.

I have since had the head off, no major damage, and also came back with compression numbers of 150 155 150 150.

Pull the ic, either have it professionally cleaned, or spend HOURS cleaning it yourself. (trust me, I had to remove my intercooler twice and spen hours trying to get that stuff out. Pull ALL the intake stuff, including your manifold, and thouroughly clean em all. Change oil, change turbo, and your golden.
