The Factory Tech Rep at Rotax advised me a couple of years ago that a Nissan
300ZX intercooler is the correct size as is the location of outlets. Dennis
Vories installed an intercooler on his XS but did use different outlet and
inlet locations. He worked with Lockwood on the development and has
reported good performance and cooler temps. I viewed the installation at
Arlington a year ago and it is very, very nice. Sorry, I do not have an
e-mail for him.

Hi, Erich --
Cooling fin area only - Oil - 10 x 4H x 2D; Coolant - 10-1/4 x 3-3/8D
x 3-1/2H. Both with mounting arrangements widening them, and fit in a
13" wide duct. But if your substituting for Europa parts, the
important spec is what they do thermally.
I would like to know too what an intercooler will do; auto enthusiasts
install them for different purposes (best power pedal-to-metal). The
climb rate should improve, but cruising at 75% power (if we knew
exactly what that is), the gain is in fuel efficiency. I don't know
either if the computer adjusts boost based on airbox temp (it limits
it above 162F for sure), but they don't say. That would nullify the
intercooler a bit, power wise. Has been done, but anybody got hard
data?
Searching the net will produce lots of hits, but aftermarket prices
are something else. Junkyards may not be a good source, as the
hotrodders will have them already. There is net of junkyards with
online inquiry for what you need, once you know what yr/make/model.
Bob Berube told me some Nissan is good fit.
In looking at my engine room, I was concerned over maintaining enough
induction airflow, or you overwork the turbo. And the additional
inlet air is aerodynamic drag, w/o knowing expected benefit.
