HI!

I would not fit the watercooled intercooler from the escort. At low
speed you will heat the air up with the 90°C hot water from the
engine cooling circle.

To fit the escort intercooler with a seperate cooling circle will be
much better but also quite expensive if you donīt play Mc Gyver and
build it by yourself (radiator from an motorcycle, electronic water pump
from Audi or VW,..).

Think about to fit an intercooler from the Golf 5 TDI. It has more or
less the same dimensions as the RS500 cooler but is just 3cm in depht.

Mathias
