turbo making odd noise

[msp03rbuld]

ok so i was driving down the road and i was boosting perfectly fine and then i herd just the motor ... my turbo was still spooling but it makes a really weird noise...... the blow off valve is doing nothing i think i may of blown my turbo anyone have any insight on this problem what may of caused this.. my thoughts are a loose coupler somewhere i cant see

[MSP_4_CODY]

Yeah Its Probably A Blown Off Coupler That You Cant See, Id Check There First, Or A Hole In A Coupler Or Somethin

[LinuxRacr]

Let's just hope it is not the bearings of the turbo.

[dstmsp03]

i bet its a coupler too!

[msp03rbuld]

ok so its not a coupler..... you can hear the turbo fan just all messed up it sounds like its rubbing up against the walls.... and i have vac but no boost... this really sucks..do you guys know of where i can get a rebuild or a used one. its sucks because i have like very little funds at the moment due to paying off so many thing... if anyone know anything about a turbo please let me know asap.. thanks guys(silverprohttp://static.mazdas247.com/smilies/silverpro.gif

[LinuxRacr]

If it is a GT series Garrett, you can replace the CHRA (Center Houseing Rotational Assembly), but the center section is not a rebuild-able piece. May need to contact ATP Turbo (http://www.atpturbo.com/).

[aubrandb3]

sounds like it is time for a gt28rs, What do you mean it sounds like the fan is rubbing. If you mean the (impeller), just remove the intake and reach in to the Turbo. Check for shaft play and free spin. Hope this helps -Brandon-

[aubrandb3]

if you grab a mirror you can visually inspect the impeller for damage. Like if you sucked up some shit.

[LinuxRacr]

If there is shaft-play, you have worn bearings.

[TheDirtyGoatee]

I don't have this issue but a question related to this. Can the car run with a blown turbo? I mean I believe it'll roll and go but will you be ok for an extended period without it just less hp than a stock ES?

I ask because I was driving a diesel boxtruck, a turbo hose blew and the guy told me to keep driving and bring it in and they'd fix it.

[Captain KRM P5]

technically sure the car can be driven without the turbo, it will act alot like an NA protege 2.0

if there are pieces broken or breaking off inside the turbo though i would not want to leave it on there and run the risk of those pieces making it into the engine.

[TheDirtyGoatee]

Ahhh.... that's what I figured. It would probably run more like a 1.6L since there is actually drag created at that point right?

[aubrandb3]

If there is shaft-play, you have worn bearings.

More than likely

[msp03rbuld]

Ok so i have found out whats up. As i was taking apart the intercooler i found a small puddle of oil sitting inside of it. Then some oil on the pipes.... I took off the mani s pipe and turbo. There is seriously something wrong with the turbo there in excessive play in the shaft. So now i gotta work hard and save up some extra cash for either the stocky or upgrade

[aubrandb3]

Just grab a upgrade, if you are buying new there is not a whole lot of diffrence in the price a few hundred bucks.

[LinuxRacr]

The thing is will they bolt up to his ride? Not without totally re-doing his turbo setup.

[JDM Sam]

uh its not better and it wont fit.

[LinuxRacr]

Exactly! You can't just try any turbo, on a given setup.

[JDM Sam]

MS3/MS6 shitty k04 with leaking turbo seals that smoke is so much better

(stfu)

[pavone]

you sir...sound retarded.

[TheMAN]

*grabs the popcorn*

[JDM Sam]

yes, your k04 ms6 is so fast. pull out a digital caliper and measure your inducer and exducer. 06/07 ms6s have the same pos k04s along with the ms3s and they all have turbo seals that go out. if you had an msp, the reason it was slow was because you bought it in bad shape or didn't know how to fix it correctly.

[turbotaylor]

Well aside from the banter here in this thread I too am having an issue with my turbo and need some advice.

Car has roughly 76k on it, owned since new, not a single mod and I can honestly say aside from oil changes i've been horrible at maintaining it. Therefore I think I may have done some damage to the turbo. Two reasons:

(1) Turbo is leaking oil as it has oil all over the outside of it can't pinpoint the oil leak yet haven't tore into her.

(2) This is the main reason. When given any revs it makes a very loud high pitch pur. There is very little boost as well. The noise is extremely hard to explain via the internet but it is definitely coming from that area.

I'm not looking to make this a crazy machine. Thinking of exhaust, intake, FMIC, that's more than likely it, so a turbo up grade is out of the question. Is the factory one re-buildable? I thought I read somewhere that it isn't. (help)

[pavone]

and why sir...do i sound retarded?

what about my post makes me sound retarded ....i would love to know...am i wrong about any thing i said?? i don't think so... please respond and lemme know!

just didnt realize garret made "shitty" turbos, thanks for pointing it out as well as your ignorance! :)

[GiJoe]

But wait the K with swap into the MSP, it bolts right up with some simple refabing of the mani, DP, and ayeah it'll swap right in...

[GiJoe]

Wheres the oil settling at? is it aroun the center of the turbo? on the intake or Hot saide?

[FLAMSP]

whats driving? Silly speedsixxx generalizing

[pavone]

Keep ur racing on the track and off the steets.

In the woods eh? Yet again proving your ignorance.. Enjoy your six. It sure is fast (and heavy).

[aubrandb3]

[QUOTE=speedsixxx;4588302]

Hey Broski,
Do you realize you are on the MazdaSpeed Protege form! All you have done is bash our cars, and the drivers. How about you take that shit over to the MS6 form, i am sure they would like to hear all about it, in fact why dont you start a thread about it. Better yet have it stickied Later -B-

[aubrandb3]

well, lets see i never owned a MSP just raced a whole lot and not only were they all slow but they all shat out nassssty blue/ black smoke.

and i already know that all the ms3 / ms6 / cx7's have the same engine and same turbo yet NO you are deff wrong about them all having bad seals cause as i said before my car has NEVER puffed out any blue / black smoke.

all of the 06 models have had bad luck, blowing motors ..turbos going bad , bad transfer cases bad differentials yet my 07 that i have owned since new has never had ANY problems so instead of us all bashing our model mazdas lets try and be a mazda community... up to you

and why am I going to measure my inducer and exducer..what is that going to prove?

PS...my k04 mazdaspeed 6 is O s0o0o much faster then manyyyy MSP's out there due to their lack of factory power and the type of people who buy them...(young kids knowing very little about driving)

You must have drove a Mustang with lots of stickers in a previous life.

[StealthWyvern]

Get bent man... so your car is faster who gives a rats ass.. Bring it down to 6psi and then you can compare but then again your engine is larger as well. yeah your car is heavier to but then again your compareing two completely different cars and class imo...

Not all MSP puff out blu/black smoke... my friends straight pipe msp only puffs out black(gas not oil), and my msp doesnt puff at all even with 75k on it.

1. very hypocritical when you are calling out other mazdas slow.
2. learn about turbos then get back to me. you're no where technically inclined to discuss such topics.
3. come to Texas, ill be happy to serve you some humble pie.

JDMSam, you are a classy man. Period

agreed...(rei)

[FLAMSP]

goddamn i love you guys....

hell i love mazdas ............

i respect what most of you have to say and your opinions and i'll try to keep my cool when writing.

in my defense i only started writing all this bs because i just gave my opinion on trying something wacky and installing a K04 onto a protege...then i get some asshole telling me how dumb i am and basically to f*** off so i lost it and started ranting.... like i said i love most jdm and i really do hate it when we all get like this.....

except my apology for maybe insulting some of you and lets continue writing about how awesome all our mazdas are! =) have a good holiday my mazda brothers!!!


Thanks for that, you have to rember when posting in the msp section not to diss the msp too hard. I understand how things can be misunderstood in the intanetz, apology accepted. ;)

[zoompastu]

I chukle reading this. MSP has a stock T25 turbo. Saab 9-3 9000 9-5 and a small year group of 900s use a T25. second gen eclipse uses a T25. Sr20DET has a.... thats right a T25!!

[jbilliel]

OK guys back on topic. I am afraid to ask this question in fear of getting an answer.

My turbo seems to be ok under all conditions except when your foot is to the floor. When accelerating hard I hear a very loud whining noise that sounds kinda like a bad bearing. But whats odd is it only does it under full throttle. Stock boost, stock everything.67k on the clock. Should I check for shaft play? How woudl I diagnose this problem? Thanks in advance!

[TheDirtyGoatee]

Might that just be the turbo working?

Is it like a whistle (like boiling water in a cattle)? Mine has had this whistle under WOT since day one. I think it is normal, soulds like a valve venting excess pressure.

Exactly... Wheew I was a little worried there.

This is also normal. Although you need to be at certain RPM to boost since you need enough exhaust gases to spin the turbo wheel, you could also slowly get your car to 6500 RPM without buiding boost by modulating you thottle. Unless you are seeing blue smoke or there is oil on your turbo (could be an O-ring), I would not worry about it.
