Here you go, Richard. See the attached pic, it shows both manifolds in
comparison.
Jimmy, you might want to add this pic to the urS4.com tech FAQ.

As for the RS2 turbo, here's an old Jani's post from my archive:
---------------------------------------------------------------
I have access to the Borg Warner 3K CD, which has info of all of
their turbos(KKK). For the Audi RS2 Avant (232 kW) the information is
just as SJ says:

COMPRESSOR HOUSING K26-2672GGCAA,
BEARING HOUSING K26 D75/51/41,
TURBINE HOUSING K24-6.12,
SHAFT&TURBINE WHEEL K24/G,
COMPRESSOR WHEEL K26-26

...except that the manufacturer of the turbo has no information of
any "Comp" RS2 turbo.

In fact, only place I've heard of a comp is this list. RS2 was never
officially raced, so a competition turbo would seem odd. This is from
the factory? What's the part number? Or is this something made by
some tuner, like a limited edition 380 hp RS2 I've also heard about,
but never seen the evidence.

And from Tom:

-------------------------------------------------------------
I had look at my new RS2 turbo today. The "Audi" part
number on the plaque is correct, but the second set of numbers on the
plaque
don't jive with numbers that I've gotten from various sources.
Can anyone tell me if this is the real thing or is it some funky hybrid.
It's driving me crazy!!  :-)

from the stamp on my turbo.
