wondering how i woudl know if my turbos are blown or not. what are the symptoms? My turbos or at least i think its my turbos are acting funny. I have liek some sort of whine in my engine which i think are comign from my tubro. Hasn't been doing this before. My boost guage is fucke dup the *** so i can't get a reading on that. If your turbos are blown do they still boost? Because my BOV still goes off pretty loud, like i had some boost. COuld this be somethign else? would a lekaign vaccuum line lead tot his or somehting?

To be clear I have a weird sound coming from the turbo area when i step on throttle even if i hardly touch the gas it makes the noise. I went to track today and ran a 16.3, even though i am automatic, this is still very slow for a rx7. My car doesn;t have the same push as before.

sounds like you have some possible shaft play in the turbos.

Take off the intake tube that runs to the turbo closest to the front of the car. Do a visible inspection of that one atleast. Give the TB a little tug and see if the turbine spins, it should spin fairly easily, just look around see if you can spot anything.


Any idea how many miles approx are on the turbos?

Well tubos are stock with the 95 car. Theres 85,000 mile son the car so i would say its the same for turbos. When do they usually go out on fd's?

Can my car still be driven? Can i drive it safetly or should i just nto drive at all?

spekdah

Any help here would be great, I seem to have the same problem

spekdah

so when people say 'shaft play 'do they mean the TB itself doesnt spin so freely? or just when you grab the TB it moves and wobbles too much in there?

spekdah

either way I suppose both is bad

ok, so your saying you dont know what boost your running (and you don't got enough money for a new gauge) and you still went to the track to run your car??? well... all i can say is good luck, your gonna need it! that and more money haha if you don't got either of those, you had better have an entire bag of bitching ready to spew out to us when your engine goes and you dont know what happen and you want help trying to fix your car

Example) rotaries are shitty and unrelible...
Example) help i think i blew my engine...
Example) why wont my car start...
Example) another one bites the dust...

this is seriously one of the most halarious post i have read for a while now! thanks for that ruff

i mean seriously, who except for you tries to fix their cars which is making weird noises and has broken gauges by going to the track and pounding it? i have never hear anyone say anything remotely like "hmmm my car might be in trouble and i dont know wtf is going on with it becuase my 30-50 dollar gauge is out of order so i think im gonna try to race it at the track and try to kick some *** there!" before in my entire life.

could be a vacuum leak, if you hear your blowoff i assume your getting boost. Buy another boost gauge asap

No Spekdah, the TB (Throttle Body) is what you use to rev your engine from the engine bay. If the turbines / compressor wheels are wiggly, then your fucked...

I agree with skunks in regards to ruff's process of illimination on his problem. Going to a track was probably not the wisest of choices, anyways... we all learn by making stupid mistakes.

I really dont know what to say in regards to this issue as I have not had an FD for close to a year now and my knowledge with specifics is pretty vauge. Really probably the smartest thing you could do with a minimal amount of money is what everyone has already advised -- buy a boost gauge.


Oh and Skunks, 85,000 is a pretty good time for the turbos to go out. Not being an ***, but with an owner like you driving the car I probably would say they should have gone out a long time ago along with the rest of the engine.

spekdah

I cannot believe that a guy who may be on a limited budget ( we dont know) would post quite a simple question to others who might have the knowledge to help him and all he got was a smart-*** reply like this !
For a start he said he noticed the problem during his track day not before it.
As far as his process of elimination - he hasnt actually done this yet , all he said was his boost gauge was fucked up, I know he wasnt clear about the symptoms but I gather me means its not reading like it should, either way we could simply ask him to tell us the reading.
Why you listed a series of Examples is still beyond me and laughing at his expense aint gonna help him. If fact ,reading through your response you aint helped him at all!! you've just been a smart-***. Grow up!

Oh and by the way 'Spoolage" when I said TB I meant Turbine, sorry bout that.

Yea,

Well unfortunatley there are alot of smart asses on this forum, and everywhere else in our society. I think its that proud American spirit that has been instilled by our mighty president Bush... laf

Anyways,

If I knew more I'd probably be more helpful, and yes after reading your post again i realized you were just abbreiviating tb for turbine. Anyways, 85,000 is a good time to replace the turbos.

skunks

what does 85k miles on turbos have anything to do with me? im just wondering becuase im pretty sure i did not mention anything about time being related to turbo death. In anycase, ill do it now i guess, i dont think that 85k miles is a good time for turbos to go out. They should last longer then that but thats in my own opinoin. can you give me any reasons why turbos should last only 85k miles? Also, why would an owner like me have their turbos "go out a long time ago along with the rest of the engine"??? I dont abuse my car (well more then any other car should be ); I drive my car like a normal car should be driven; i change oil frequently and I have my boost undercontrol (at stock levels); I have done damn near every reliblity mod out there and I'm still trying to figure out more; I keep my temps between 180 and 190 degrees and I dont get on the gas till im warmed up. im sorry but i just dont get it.

P.S. my car is running great , has been for about 3 years now hehe

upon rereading the time post of his post, i guess it might have happened at the track but then again. I figured that his second post was posted after a while where nobody responded and he wanted to bump up his post or something like that (you do get 30 mins to edit your post, i kinda wonder why he did not edit his original post instead of reposting another one 3 mins later... i know i know, POST ***** HAHA. just kidding ). he did still run his car at the track with a broken boost guage. personally, the way i read the post was that

1: he started to hear the weird sounds
2: did not know boost levels
3: posted first post
4: went to the track anyways
5: posted second post

(that is the order in which he typed it so thats just how i figured it went).

Skunk, guess you have no idea what could be wrong with his car and just decided to lecture him on some bullshit instead of helping him out.




Anyways, it sounds like your turbos are on their way out if you are getting the whining noise (sounds like a tornado warning siren kind of?) and you car is not boosting. I had the same problem with my primary turbo just before the turbine (exhaust) wheel broke off and started dumping oil into my exhaust (talk about a james bond smokescreen). If the primary turbo does not hit over 7-8psi, then the secondary turbo will never come on line and continue boost past 4500rpm.... therfore you will have no boost (and a 16 second car).

Time for some low mile turbos, or 99'spec 280hp turbos.

Look to spend between $300-$2600 on some stock turbos. You may find some BNR turbos for $1000-$2000 if you are lucky (they just don't spool quite as quickly as stockers).

skunks

yeah, i figured that i would have to post something (the way i read it the first time, it was just bugging the crap out of me not to post something. i guess i have too much time on my hands). i mean other then what was already posted, im not sure what exactly would have helped. spoolage did already gave the best advice. at least i did mention that he should get a boost gauge

Well, at least you are not attacking me for pointing that out.... nice of you to do that.

Actually i did not go to the track knowing my turbos had problems. My boost guage was reading 10psi before it went out so bosot was fine. Then it went out but i had plans to go to track anyways. That morning or the night befoer i went to trakc i heard some nosie from engien but very veyr light would leave and come back. AFter track was different sotry was a loud noise. So going to the track fucked somethign up. Yes i knwo my fault for going without knowing my boost .

hahaha 1234rotor, u have it right on the dot. The first thingt hat came to my mind was that it sounded liek a tornado siren. Yes it is my primary turbo that is makign the noise, but pass 4500rpms the secodn turbo does come online...still makes the noise but nto as loud probably because the primary isn't workign as hard ocne the seocndary is on. If my turbo is blown would my secondary one work?

Btw for eveyrone else i think spoolage said it, I don't drive my car hard. First time to the track so i have never actually raced my car because i don't really race on streets. I take good care of it, oil change when it needs to be done i add lubricants to the gas, warm it up before goign anywhere. First time its acting up on me

DCrosby

Stock turbo's typically have 1 of two major issues,
They either work, spool
Or they don't.

If they spool, (you'd need a boost gauge to figure this out, since BOV isn't a valid indicator) then there is a possibility of noise, or oil. Noise you can hear, and will usually sound like metal grinding. And Oil you will see in the rear view mirror, in the form of blue smoke.

Now if you're missing a turbine blade, or something else major, noise is usually the symptom. Allthough a crooked blade can cause starnge boost issues, but is inevitably followed by noise, since eventually the turbine will discintegrate due to an imbalance.

Get / Borrow a boost gauge, before you start chasing ghosts, or discribe what the one you have is doing, since it's possible that the gauge is fine, and the turbo has the issue, and is showing it in the form of the boost bouncing all over the place...

Oh and a bad 1/4 mi time, can be a mirad, of issues, from a bad clutch, to poor driving... just cause you own, a bone stock, FD doesn't mean it'll do 13.9 everytime you drive it....

Not trying to take this thread from ruffryder but my car is starting to do the same thing and it still feels like it is boosting just not as much as it used to and i only hear the whisteling in between 5500-6500 rpm's. I dont have a boost gauge yet because i got my car not that long ago but it was windy that day and it may of felt like it was going slower than normal. Are my turbos goin bad too u think? 78000 miles on them, the car is all stock
