Cylinder head
The following turbo-specific modifications were
made to the cylinder head (in relation to the
2.0l FSI):
● sodium-filled exhaust valves
●
intake valves with reinforced seats
● roller rocker fingers optimised for rigidity with
a reduction in cam and roller land width
●
valve springs rated for increased spring forces
(identical valve springs are used for the intake
and exhaust valves)
In addition, the intake port geometry has been
revised, enhancing the tumble effect along with
knock resistance and running smoothness.
The high-pressure pump mounted on the cylinder
head has been installed rotated through 90°.
