From 2019, GP Turbos' online shop filed its hybrid turbos by car make. The first categories were Audi, BMW, Porsche, SEAT, Vauxhall and Volkswagen. Škoda followed within a few months, and by late 2020 Mercedes-Benz, Renault and a category for other makes had been added.
Many engines wear more than one badge. A Volkswagen Group 1.9 TDI (turbocharged direct injection) diesel can sit in a Volkswagen, an Audi, a SEAT or a Škoda, and GP Turbos often listed one turbo for all four. So when you ask about a turbo, the engine code and the part number on the turbo matter more than the model name.
A hybrid is built on the factory turbo: the housings stay, re-machined where needed, and the parts inside are upgraded. It needs supporting modifications and a matching engine calibration to deliver. If your turbo needs putting right rather than upgrading, see turbo rebuilds. For how a hybrid is put together, see hybrid turbos.
