This is all on a rebuild motor. Got it to start but it was idling really rough. I had to hold it at about quater throttle to keep it idleing. After about 20-30seconds of that it would idle by itself but still rough. Then i got out of the car and saw that my turbo manifold was cherry red...not good. So i killed the car turned the heat on, my electric fan on, and put a box fan over the turbo to cool it. Hope i didnt fry my turbo. So after it cooled i started it agian and as soon as it started i went and moved the distributor and tps sensor and got it to idle smoothly but now my manifold has a crack in it that i will weld.

Q: What i want to know is if the timing is what caused the manifold to turn cherry red?

If the timing was way retarded would it cause that. It seemed like there was a huge load on the motor even though there was none. Tonight i will weld the cracked manifold and tomorrow i will time it and set up the tps. I hope i didnt fry the bearing in the turbo or cause any damage.

The manifold will glow if you have a fuel problem or timing problem. What motor is this? what do you have the timing set to?

it is a ka24e. I am not sure what the timing is at. I am going to be getting a timing light tomorrow. When i turned the dizzy counter clock wise(retarding)that is when it started to idle better. On another forum i was told that advanced timing will cause that kind of egt's at low rpm. I will know tomorrow. It shouldnt be a fuel problem. The whole fuel system is stock with a walbro pump. Remember that the manifold was glowing at less than 2K rpm's.
