The amount of reusable out-of roundness in a turbine housing is a debatable issue among turbo rebuilders. However there is a difference in quality among rebuilders and this is a conservative recommendation intended to emphasize the importance of this commonly overlooked step. Completing this process can help you avoid the situation where owners feel that their engine just doesn’t run as well since they serviced the turbo. Exhaust gas leakage can be an elusive issue since you can’t stick your head under the hood while the engine builds boost. It’s better to measure and know for sure. This is also another reason why a turbine pressure gauge is valuable in addition to a boost gauge for any turbo setup.
