in comparison with the temperature of the exhast gasses flowing through it, the heat contrabution of the turbo bearings is negilable. it is enough that it needs to be controlled for the bearings lifespan, however the amount of heat it generates in comparison is not worth worring about. the turbo needs pressure to operate, and since the volume is fixed, the temperature goes up as a result. worth noting however would be the difference in pressure between the exhast manifold tot eh turbo and the downpipe out of the turbo.
