Do you have a Holset turbo, commonly found on Dodge/Cummins diesel engines, and are unsure about parts interchangeability and upgrades? Or did you find one for sale and are not sure the description matches how it appears?

In this video we show how to identify common Holset turbochargers from early generation H1C and H1E, to HX35 and HX40, to HY35, HE351 and S300 turbos. We also discuss strong and weak points, upgrades and common modifications made to this popular turbo.
