Turbo is ******! take a look

[zzMSP03.5]

looks like something i would see in my nightmares!

Yea im kinda thinking about doing that myself... i have had nothing but issues since i have installed the unichip and i am still getting beat... i want a faster msp crazy sleeper.... just have to come up with the dough...

 

[tekkie]

wow, you know that thing is not for disposing of trees right?

something fell in there for sure by the look of it, maybe a screw or something from your intake?

that reallys sucks ass man

do an autopsy on the turbo, block, etc.

The tune was good? The car happened to blow up as soon as it was "tuned", what was the A/F and timing throughout the tune at? The motor sounds like it hit a lean spot or something.

Blew engine, ****** Turbo.......sorry to hear that...

 

[altspace]

Doh! Not coming to the meet then?

 

[smo0f]

you didnt hear any noises while this was happening?

tune was fine, i checked the plugs, no detonation what so ever. plus no audible knocking so if it was bad enough to blow it the engine the plugs would show something. plus i tuned it rich, he was at 10.5 @ wot before the lsd blew.

and no it hadnt blown up as soon as it was "tuned". its been on a rich tune for a while that he didnt get fixed. on top of that the day the lsd broke i checked his turbo for shaft play to make sure all was well. his turbo was fine, then the lsd blew, and when he got it back the engine blew within 24 hrs. so after leaving the tranny shop, within 24 hrs the turbo was chopped to bits (filter has no holes and intake tract was sealed when I left it) and the engine blew. on top of that his wg line had a hole...so yea must be the tune...

Damage like that is possible JUST from the blown motor... at least in my mind it is. That damage looks to me like like it came from the shaft/compressor blades being pushed (out toward the intake) into the compressor housing. It would not be the first time that somebody lost their turbo due to a popping motor.

Just a thought... I don't think that anything got in there to chew those blades up.

sweetlou wasnt in the car when it happened. so this cant be answered technically.

so when a rod goes it has enough force to come back through the intake, though a maf (on presure side), fmic and back to the turbo and blow a compressor wheel, all without losing any pressure with a hole in the block? i dont get it, just seems impossible to me. hes got pits all inside the intake of the turbo...like something was jingling around.

 

[smo0f]

that sucks. well, when my motor blew, the dealership wanted to change out my motor and turbo, even when the turbo turned out to be fine. so maybe it's expected that when an engine goes, the turbo goes too due to debris?

 

[terbow]

yea i was asking, i dont know personally, just seems kinda crazy to come back all through that, not damage the ic at all and chew up every other turbo blade. not all of em are damaged. just seems wierd to me. thats all

 

[smo0f]

it's a mazdaspeed protege. 'weird' is the norm.

Haha, that's not at all what I meant... that would jack up the other side of the blades anyway. But... if you think of how the shaft starts to get "play" after awhile, it is a in and out type of movement. Now think of that same movement while the blades are spinning, and think of a force great enough to make it hit the housing... see what I'm saying? Also, those pits you speak of could possibly be from the small fragments of blade hitting the inside of the compressor inlet after they were broken up.

It's harder to tell while looking at pics than it is for you there in person, but I just wanted to throw in here that it didn't HAVE to be something getting in the intake, like everyone in this thread is saying. Tell me this, is there any damage to the compressor housing where the blades WOULD hit?

 

[terbow]

oh so u mean if the turbo had to much play for whatever reason and maybe overboosted and then hit the housing, self destructed, then went into the engine, and made s*** go boom. valid. makes sense.

i dont think anything got in the intake unless it was rmoved cause filter was good and it was sealed. plus the pits look like they are shooting outwards.

 

[terbow]

we were tuning it at like 6 psi btw.

 

[505zoom]

It's kind of a long shot I know, but like I said, other people have broken a turbo JUST from blowing a motor, so it's not impossible. Just a quick glance at the pics makes it look obvious that something got in there, but I dunno, it just seems unlikely to me that a rock or bolt would damage ONLY every other fin almost exactly the same, and leave the other ones alone.

 

[terbow]

right. also fishy to me, and when u blow holes in the block its kinda hard to preserve ANY evidence of material being the culprate. when i rip the block apart maybe there will be some signs of a story.

Wow, I never even thought of the compressor wheel hitting the housing, but when you go back and look at the pictures it makes more sense than something getting in the intake.
