200TDI engine but what intercooler?

Hi folks, Picked up a 200tdi disco engine for decent money recently and i'm starting to gather the parts to complete the conversion. I didn't get the radiator or intercooler with it and I'm trying to figure out what to do. Should I just look for a discovery rad with inter cooler then get the conversion kit?
Or can I use my existing radiator and oil cooler but buy a large intercooler to fit in front of the rad and match up the pipe work??

you could do that, disco and defender intercoolers are the same by the way, but radiator/intercooler frames are different but the disco one is an easy mod to fit
