There are many approaches to turbocharging thanks to technological advances. Sequential turbos were once the rage (remember FD3S RX7s?) to combat lag. Twin scrolls are quite popular these days. Instead of a single track, you have two tracks. One for low pressure (smaller diameter) and the other for high pressure (larger diameter). Both within a single turbo housing package. This minimize lag and deliver optimal turbine efficiencies. I remember first reading about it in the Mitsubishi Lancer EVO X.
IIRC 911 Turbo uses variable geometry turbos with tiny vanes that moves to maintain efficiencies.
Some mfgs are using electronic turbos too (see Audi Q7). It reminds me of the Surbo. Lol! But this time it's not fake.
