this is a cost effective upgrade if you're looking for a bigger radiator. the evo radiator fits with a few modifications, mainly, the way the fans mount. (a few zip ties will do the trick). i paid 100 bucks shipped for the radiator.
here are some pics. as you can see it's more than half as thick but takes up the same total amount of area.
