Intercooler is sorted. Found that the Escort 2wd Cosworth has a nice size intercooler that will fit between the top of the chassis and nosecone.
By removing an intercooler infront of the radiator this should help quite a bit. Next step i think is to find a Westfield SEiGHT V8 Radiator.....

Or an alternative that is no more than 580mm x 350mm
