Turbo Running Hot...

So I just got my old 15g replaced with a new one. My father did all the work himself, but there's a problem...STILL running overly hot. You can look at it and see it bright red...Only drove it 20 minutes so hopefully no problem. Car still makes boost, got a new cat on the car...So either exhaust system is fouled up before the cat? Getting no water? Getting no oil?

WHAT THE HELL, someone please give me some ideas and point me in a direction. How easy is it to check the lines, or would that involve taking off the turbo <_< ?

EGT's are hot or the exhaust housing just glows?

If you've got a new cat and the housing is still getting red, trust me its pretty normal after a hard (HARD) drive.

Do you have:

An egt gauge?

A wideband?

No EGT gauge

No wideband

And what Joseph said, it's after normal driving...20 mins of normal street driving did it today, and barely boosting the car even though it's well capable of boosting to 10psi.

Also gas mileage is at about 9mpg :o , I get heavy bog/hesitation still around 3,000rpm

didn't you have a thread about having a bad cat? If you never got this fixed could be the prob, MPG is a common symptom. Correct me if i'm wrong but a clogged cat clearly won't allow as much exhaust to flow making the turbo hotter

Naw, he said he had a new cat.

Honestly, it sounds like a cooling problem... IIRC, these turbos are water-jacket, so check that and the oil. It sounds like you have other problems too, though...

OK, sooo my day of having the car apart is done with. Found a tiny clog in a oil feed line, and in a water feed line. Nothing too major, but nothing too small. Car will be tested in about a hour, wish me luck. I still don't think that this is gonna solve some of my other problems, but hopefully it'll eliminate this one.

My turbo has a pewter red color to it now <_< . It's brand new so I hope it got a chance to be broken in before it faced such bad heat. My old turbo is still in good shape, sooo I'm kool in that department for now.

Tested the car this morning, SAME problem still existing...Now that I know everything's hooked up right with the turbo, lines are clean, new cat so no exhaust clog. What else does that leave? Is it possible that somehow coolant or oil isn't getting circulated or even moving to the turbo? I don't see how that could happen but still up in the air about the whole thing...
