why is my turbo getting super red and hot?
i fix all the vacuum to the turbo and all valves seem to be working when i took them all out to clean them. the air filter is brand new. and the spoll in the turbo is spinning freely when i stuck my hand in to spin it.
your catalytic converter or muffler is restricting the flow of exhaust gas . most likely it's the converter ...PBN
OH yea , your converter is clogged up or the ignition timming is slow .
If you just came back from a hard run or a long drive its completely normal.
Take off your lower oil feed line and clean it, and the k03 should never get that red and hot if it has good oil feed. They dont make that much boost.
