Alpha radiator versus beta radiator
 

Do you have to swap radiators when doing the beta swap? Will the beta one fit ok or do you have to fab up something to make it fit? Or is the alpha one just fine for the swap?

Alpha one is fine. Especially the full width Alpha radiator.

They are sufficient for the cooling the engine but I think the extra heat from the engine puts extra stress on the plastic at the top.. I have blown out 2 rads so far...
