Your question is too vague. Give more detail.
Also, have you searched the forum for a possible answer? This has been discussed a few times already...

The stock radiator (or OEM replacement plastic tank from Koyo/Calsonic) is very good. There is little to be gained from buying a larger dual core aluminum one.

Now stop starting new threads and search.

You can get a thicker core, I have plans for one someday. The thickest radiator I found was a 1.57 by both Mishimoto, and Mizu, I don't know which is better, but a thicker core usually cools better.

if you can flow air through it.
it is actually better to have a thin core and additional face front size--but due to space limitations--thicker cores where developed.
If you go to a thicker core than oem you really need to upgrade the fans and their controller too.
