looks liek a fuckign mechancial bear started clawing at that thing... then someone smeared **** over it...


so... gonna try to use that housing again? heh,

did the seal hit the compressor?

 

No damage to the hot side of the turbo. A very very light scratch on one fin, more or less in the buildup that was on the compressor wheel.

I am trying to track down the housings and a new rotor now.......

 

I have 2 s5 n/a housings, just need to grind out the diffuser or swap the sleeve. One is questionable in a spot but is perfectly smooth, other one is in awesome condition. Both 90k original miles, PM me if interested.

 

aight, back to the original post from me, as for mods turbo stock,intercooler stock, i have full 3" exhaust with a pre muff(could be a cat , dont look like one.. no emissions where im at) 3" downpipe, running just rich as **** right now tryin to figure out the prob pretty sure its my injectors(there stock) , FCd, Blitz blow off valve, non ported wastegate, walbro pump, SAFCII yet to be tuned with(waitin on money to hit the dyno) just seems fucked, im having boost problems right now as well , wont hit full boost till around 4500-5000rpm also thinking vac leak somewhere , any one experienced any problems like this in similar situations???
seem to be running so rich its boggin my engine and slowing it down? to the point were im matting it and am smelling gas seems like rpms are rising slow... HELP!

 

ok i just layed down on my bed thought about this **** and i think i might have it figured out, out so lean = hot (red glowing turbo), and me smelling gas which i probably shouldnt right? maybe i got a fuel line leak somewhere in the engine bay causing lean running and the smell of gas, fuel pump and inline filter were changed 10-15km ago.. any ideas where it could be leaking? ima take a visual but i think its gona be hard to tell because the smell only occurs under driving situations at full throttle???? any one had this before?

 

no, im pretty sure that your running realy realy rich. you will smell gas like crazy and since its so rich your going to have gas igniting in your exhaust that didnt ignite in your engine making your turbo glow like crazy. my exhaust manifold was glowing on my car when it was rich and i have an N/A

 

yea thats gotta be it , i just took off the intercooler looked around for a good 20min no signs of leaking, and it wasnt my turbo glowing red it was the wastegate, but still. gotta figure out what the hell is making it run so rich, my boost gague reads -12kg or whatever it is, so i dont think theres a vac leak... gotta be injectors what do ya all think? my only concern is that my engine is a mazda reman, with like 35,000 40,000km on it wouldnt they put in new injectors???? and if so what would even make them go bad so early or what else could be causing the engine to suck in so much gas, im clueless?????????????????

 

^I agree. Thats what I was first thinking with the off timing, car was running rich, fuel not burned goes into manifold, bad timing+heat on manifold causes it to burn inside.

If he was running lean, the heat you see on his manifold would also be in the engine, and you'd defenitly be in trouble (detonation).

*edit*
I wonder what corky bell would have to say about this?

 

I remember when I had the silencer on my car, it would idle for like 2 mins and the turbo would be glowing like crazy.... It took a sawzal, a flat head and a hammer to take out that stupid silencer....

 

any ideas on the injectors from a reman, id think that they would put new ones in with the rebuild, if so its kinda early for them to be ****** up aint it 40,000k?

 

I doubt its your intectors. Too rich can cause a turbo to glow just like too lean can. Its much more common for lean to = heat, but if it is way too rich, that can cause excess heat too. Also listen to the people on here and check your timing.

 

mine glows too, but you can only see a very mild glow at night. Everything seems fine though

 

so you think that bad timing will cause it to run so rich, to point where i can smell gas when im flooring it driving? it just doesnt seem right . the flooding is pretty bad.

 

though this may be unrelated... I hope...

My 91 N/A vert gets real, real hot (I haven't checked if it glows yet.) Well, after I let it idle for about 4-5 mimuts, cat seems to start to raddle and hit against something near by. I haven't been able to visually locate exactly where, but it seems to go away when I put it into any gear. It seems to match the rpm, but can't exactly find what the problem is. Could this be a cat problem?

Thanks!

(edit) Martin, I love your lights. Could you tell me if it's a kit? Thanks.

 

yeah when my turbo did this for the first time I almost had a heart attack. I thought i blew it up but from what I have been told is this is just because the turbo is so old.

 

"Old" turbos should not glow because they are old.

Running excessivly rich will cause the turbo to glow.

It is normal for the turbo to glow slightly after running the car hard for a little while.

Failing or clogged cats will cause exhaust gasses to back up, and can cause the turbo/manifold to glow.

 

I've only seen a glowing turbo and manifold once, off my friends talon after a few high boost runs.. and damn, was that thing glowing.

 

well i think i have come to the conclusion that my TPS is messed, and my timing is probably off, and its not the turbo glowing red, its my wastegate but still it glows red hot after only like a 10min drive of easy driving, so i gotta get a new TPS and go from there i guess.

 

Hrm.... I also seem to have the same problem... glowing turbo after light/medium driving. And its no light glow either - full on light up the entire section of my engine bay and maybe light up the ground a bit too.

So timing - how do you go about checking it and correcting it if its not right?

Thanks,
Jonathan

 

Turbo + precat glow
This is after 30sec downhill and 30 sec uphill run...
My injectors were bad then...
