I hate to be 'that guy' but in my first post I saw plenty of ways to bring the temps down without buying a new radiator. With the mods you've made, I will now go on record to say you need a bigger radiator. :) I'll go so far as to guarantee you can bring temps down 20+ degrees.
I'm not saying some of the other ideas may help but now you are starting to spend some dollars and tome on some expensive repairs. The radiator can cure some other efficiencies that you may or may not be able to find.
