Rear mounted radiator ???

[1303C2/3]

Well i'm not sure but I think it was the German ''VW Speed''magazine 2002/1 where a 2.2 l Subaru flat four powered Oval window GL bug had a rear mounted radiator fan set up. The firewall had been cut than turned 180 degrees and welded in again upside down. The radiator was an Audi unit (dont know which type) and twin electric fan set up and shroud were Opel. Together with some sort of wind deflectors from under the rear torsion tubes directing air tothe radiator might provide enough cooling I think. It should work with your WBX engine. A friend of mine has a 1.9 lt DG engine in his Fastback with a small an old fasioned Fiat 131 radiator up front in the spare tire location and only a very small air intake under the front bumper. His engine runs very cool even in the hottest summer days. Good luck!
