Every two-litre turbo four, every badge. B48, EA888, M254, M139, 2.0 T-GDi and the rest.
2.0L Club exists because most modern performance comes from a two-litre turbo four, and the knowledge transfers across badges: carbon build-up, intercooler heat soak, oil choice, tune headroom, and which tuners understand which platform. A DQ381 behind an EA888 and a ZF8 behind a B48 behave differently once there is a map on the car, and that is the kind of thing owners compare here.
For verified owners of any car with a 2.0-litre turbocharged four-cylinder engine, petrol or diesel.
What happens here: engine-platform deep dives (oil, coolant, carbon, turbo and gasket behaviour in heat), dyno days and tuner comparisons, club drives that mix badges around one engine, a parts cross-reference maintained by members, and shared long-term reliability logs.
