Depending on use (it's not going to be a burnout car I assume) then any of them should do. A friend has an eBay alloy job in his 20V AE86 and it works fine. An old rooted two core Gemini radiator (about the same size as an AE71 rad) kept my 4AGZE cool unless drifting flat out in 30+ degree heat. Another option is an ST162 Celica radiator and thermo fans, which is pretty similar to the Excel setup. It's kept my 4AC cool even on track... yeah, that's not that impressive is it.
I'd choose the one that would be easiest/cheapest/give you the most bling.
