glowing turbos
Is there anything other than injectors spraying too much fuel that could cause red hot glowing turbos?
I searched and the only cause I could find was dumping of fuel.
I replaced my turbos (smoking) with a set of low mileage stock twins and now they are glowing at idle.
The only difference that I can find is that the engine is idling high now (1500 rpm). I think this is because of a missing vacuum hose that i found when working on the engine. I am guessing that i just need to adjust the idle not that the hose has been replaced.
Any advice would be appreciated.
Thanks,
dave

Well, the theory that i have seen is that if the injectors are dumping fuel, it burns in the turbos, causing the excess heat.
I will check the coolant lines.

That glow has got to go..........
You sure the twins you removed didnt glow too????
I have seen this on a couple of FD's w/twins. All of those had downpipes & cat backs but still had a cat or aftermarket perf. cat. Installed midpipe, glow was gone.
What injectors are you running??
Why did you replace the twins ??

could be:
1. ignition timing to retarded (something wrong with tune)
2. you're detonating and its causing the ecu to pull timing a lot - meaning there is an underlying issue with the fuel system and control
3. could be as simple as a clogged or almost clogged catalytic converter or a flex pipe that has collapsed on the inside
it has nothing to do with the coolant lines running to the turbo. those only cool the center section of the turbo to avoid bearing failure. it doesn't cool the turbine housing

Actually out of all of the things mentioned above, I wonder about the nuts being tight enough. If it were leaking air it would run lean and hot. I pulled the turbos yesterday, and the nuts/bolts came off easily enough, granted they were off not too long ago, but still......
I have a fairly new Bonez hi flow cat on the exhaust. I suppose it could be bad, but what are the odds. It probably only has maybe 5k miles on it.
I replaced the twins because they were leaking oil into the intake tract.
Stock injectors.
Cant' say for sure that the old ones didn't glow, but i never noticed it.

i would imagiine not enough fuel if your worried about your injectors.....hot turbos come from hot combustion or to much boost for too long.....and possibly lubrication or cooling issues to the turbos.....

Hope this helps. The owner of that particular car is Paul, he is PC1138 on here.
