turbo life expectancy-"94"

[joe_murphy]

generally speaking how many miles can you expect the turbo to last?

[john8662]

Usually, throughout the life of the engine...

The turbo as an assembly (CHRA, wastegate flapper/bushing) should last around 150-200k miles, if shutdown and allowed to cool properly after hard use.

Oil quality and air quality among other things weigh into the life of the turbo...

My 94 has 255K on it now and it is the original and was only apart to clean things at 240K during the overhaul.

As John says, clean oil, clean air and a proper cool down will really help the life span.

At 255K Im not complaining

Thanks for the infor.-sounds like I don't need to worry about it for awhile

Depends on how the truck is used, as a grocery getter as little as 150,000- 200,000 miles but as a vehicle seeing only highway miles 1,000,000+.

1,000,000 miles? this is based on one you've seen or driven?

[bcbigfoot]

Based on the fact that highway tractor trucks turbo's routinely get this type of service and more. The 6.5's turbo if used in a high mile applications would have no reason to also see this type of service. It is one of the few pieces on the 6.5 that is of a design, quality that would far out last the rest of the engine in service life. The turbo on the 6.5 has a very easy life compared to 90% of turbo applications were exhaust temps remain high and boost psi is also high in the 25 to 35 psi ranges for most of thier service life.

ok I'll buy that. If you think the 6.5 turbo is built as well as the big guy's turbos.
