An AU with E series sized accessory pullies would be underdriven.

there are a few differences that make it a no go..
harmonic balancer from e series cant be used.
the water pump pulley has different bolt spacing, I guess it could be re drilled..
but from what I can see the major part in underdriving is the harmonic balancer size. which no one does for au.

Keep the AU harmonic balancer. Turn up a custom pulley set in E series sizing but Au offset for the water pump, alternator and power steering.

Where has the vision gone people?

I think it comes down to alot of money and or work to get custom pullies for such a small gain..

What happened to the EGR spacer on the 200kw & 220kw motors? I notice I've got one on my engine (which I assume is a 185kw motor :cry: ).

There just isnt enough $$$ in it for companies to pick up and start producing them(underdrives).

the au don't run the egr so the 175,185 and 200kw runs the same throttle body with that blank spacer.
the 220kw just has a deeper throttle body with no spacer.
