Explain why? The intercooler in a turbo installation cools the air charge
from the turbo to the intake. The turbo does not run at a different
temperature. Cooling the air charge increases the air density and therefore
increases the power and the whole purpose of the IC is to provide the
maximum temperature drop without reducing the flow.  It is for this reason
that some people (me included) use a water-cooled chargecooler (not stock!)
to keep the charge temperature right down. On my S4, the turbo is also
water-cooled and doesn't require the warm-up, cool-down cycle that regular
turbos need to remain reliable. Are you confusing this with intercooling as
watercooling the turbo increases its life?

Back onto the subject line, I would change my 1.9 waterboxer if I could get
the 5-cyl parts in the UK and find a knowledgable garage to do the work.  I
have been offered a complete Audi turbo car for 450UKP (about $600) with
good engine as a donor and then I know that I have all the bits I need
(including the Audi leather interior).
