i think you need a reverse water pump on black top but dont quote me?

the roose motorsport do conversion hoses off the shelf and a guy on ebay sells cvh thermostat housing to zetec head adaptor plates


as for management the cheapest way would be to get a megasquirt ecu kit from boostmonkeys and have karlos g fit it and mapp it......

dont bother with ofab as a zetec turbo chip alone is £250
