NOTICE: Whenever turbocharger air intake
system components are removed, always cover
open ports to protect from debris. It is
important that no foreign material enter the

The Focus RS 2.3 Litre EcoBoost engine is fitted with
a NEW twin-scroll turbocharger. The turbocharger
incorporates an internal bypass valve.
The turbocharger is an exhaust-driven centrifugal air

the "hot" turbine and the "cold" compressor. Bearings
are sleeve type and lubricated by engine oil. Oil is
