There’s no doubt that the OEM’s designed some pretty decent turbos in their day, and that some especially still do a great job. There’s not anything particularly special about OEM turbos but all in all, getting a replacement turbo from the OEM will serve you pretty well, as long as you have the money for the OE upcharge.

One interesting case to note when talking about OEM turbochargers is Cummins’ turbocharger division. Cummins has a division called Cummins Turbo Technologies, sometimes better recognized by the name Holset. Holset used to be an independent engineering company that specialized in turbochargers, but was bought by Cummins in the 1970’s. Cummins didn’t officially change the name of the division until this century, and the turbochargers produced by the division still have the name of Holset. Holset turbos are known to be great quality parts. Even though they’re a division of Cummins, however, they are still termed an aftermarket turbo and there are Holset turbos made to fit engines that are not manufactured by Cummins.

As if the whole Cummins-Holset thing wasn’t confusing enough, when talking about aftermarket turbos, you may hear terms like “house-brand” and “branded.” In all reality, an aftermarket turbo is an aftermarket turbo, regardless of brand, but we’ll go more into depth on the difference between house-brand and branded turbos.

House-brand turbos are usually turbos designed and manufactured by an engine parts supplier or manufacturer. Sounds like a normal aftermarket turbo, right? Right. The term “house-brand” tends to throw people off because it’s thought of as a lesser quality, which isn’t necessarily the case.
