For Escort RS Turbo`s, NMS recommends the GRS Motorsport (http://www.grsmotorsport.co.uk) large Intercooler as the best off the shelf product available.

However, this is not the only solution and we produce two alternatives
both of which offer improved ACT's over the GRS and similar items. Shown below are two
such intercoolers for the Escort RS Turbo. These intercoolers utilise either
two or three Sierra
RS Cosworth Intercoolers welded together to form one huge intercooler
capable of keeping Air Charge Temperatures as low as possible, and with
almost zero pressure drop across the intercooler, it makes for an
extremely efficient intercooler setup. It is not as straight forward as off the shelf bolt on unit's
though, as it requires some modifications to fit, and makes fitting a
large fan virtually impossible but is the ultimate
intercooler for an RS Turbo. Please note that the triple version is only
available for the S2 ERST, the S1 ERST has insufficient space without
major remodeling of the front end!
The twin and triple Cosworth intercooler conversion are single pass intercoolers which means the intercooler outlet is on the opposite side to standard. This requires the charge cross over pipe to be re-fabricated in order to complete the installation. We produce a mirror image of the original item giving a factory look but improved function! These conversions are all produced in house and along with a new cam cover we can offer a range of colours and finishes all painted in our low bake oven on site.
