Uhm....should the turbine housing be red hot?

Yeah....that.

I opened my hood tonight right after i shut her down and....lo and behold, its glowing....with my exhaust manifold too. Why does this seem not normal?

Perfectly normal. Don't worry. Get into the habit of letting the engine idle for five minutes after a long run. At least until the auxiliary fan has had the chance to cycle on and off once.

It's pretty normal if you've done some harsh driving, or long driving. Though if your timing is off, the turbo and manifold can glow way quicker (more or less 5 minutes of just idling) than when the timing is correct.

based on my personal experience.

I remember setting my boost one night with the gillis and after having gone at it with an M3 BMW on the highway raising my hood and saying GEEZUS!! It reminded me of the Science Channel's "The Surface of Our Sun".

Indeed timing can definitely be a factor here. If your timing is too far retarded, some of the combustion is actually occurring in the exhaust manifold and into the turbine housing. In fact, rally cars often do this purposely to keep the turbo spooled, shortening turbo life in the process. If you're seeing the hot side glow under non-boosted conditions, I'd try advancing the timing a couple degrees.

Good to know...although im sure this vehicle could use a good timing adjustment anyway. It still stumbles under full boost. With or with out the KS. (no pinging though)

Also...something that helps is that turbo cool down pump from the MBZ that the PO put in.....that thing is great. When i was under the hood watching it glow, the pump came on and started pushing coolant around again....i could pretty much watch the glow fade....

I think you might just need new plugs (NGK TR5) cap, rotor and wires all Motorcraft (rotor is either press on or screw on), all caps are the same, wires WR4011C's... See if it clears up. All should be avail at local auto zoo.

By all means, check the timing before doing or assuming anything!

From the TFI Follow the leads to the spout, disconnect it or pull pill depending on which one you have, hook up a timing light with the sensor on # 1 lplug wire loosen distributor bolt and set to 13*BTDC...this is to be done with the car warm.
