Radiator options for MK1 Cab with 16v and twin carbs

Can anyone recommend a suitable radiator and pipework setup for a MK1 cabby running a KR engine on twin carbs?
 

If my memory hasnt let me down i think a corsa rad used to be a common mod, its slightly smaller and fits under the slam panel making for a bit more clearance.

had the same dilemma running a 9a with Omex throttles, ended up getting a custom made rad from a company that advertise on ebay, they sell the polo rads for caterhams but they’ll make one to your dimensions, thicker core rad, pipework wasn’t too bad, bought some silicone elbows and stainless swaged tube and made it all fit without too much hassle, you will probably need to chop the ally cylinder head outlet pipe and re-weld it to point down more to clear the carbs or buy a ready fabbed one, I run a variable speed Spal fan driven off the ecu which shifts a lot of air at full tilt, had no overheating issues,  reckon a good quality fan driven off the normal temp switch would probably have done the job, pics attached
