I think mine might be the dimensions you listed, i'll have to check. There is room for one that is slightly bigger, not much bigger. Once you go bigger, the piping is more tricky getting around the A/C. The hot side is the only hard part of the entire FMIC install. The cold side is really easy. <p>Anyway, i'm curious why you want something bigger? With a stock turbo, the IC that Phuzzy sells is plenty. Did you already buy it or something?
I have a 26x12x3 and it takes no more bumper modification than Phuz's smaller intercooler.<p>You do still have to cut away part of the lip on the bumper, but you have to do that with the Phuz intercooler as well.
Here's a few pics of it. Definitely looks better in the mouth of the bumper IMO<p><IMG SRC="http://img.photobucket.com/albums/v724/tarmactrr/Volvo/DSC01931.jpg" BORDER="0"><p><IMG SRC="http://img.photobucket.com/albums/v724/tarmactrr/Volvo/DSC01937.jpg" BORDER="0"><br><IMG SRC="http://img.photobucket.com/albums/v724/tarmactrr/Volvo/DSC01942.jpg" BORDER="0"><br><IMG SRC="http://img.photobucket.com/albums/v724/tarmactrr/Volvo/DSC01961.jpg" BORDER="0"><br><IMG SRC="http://img.photobucket.com/albums/v724/tarmactrr/Volvo/DSC02100.jpg" BORDER="0"><br><IMG SRC="http://img.photobucket.com/albums/v724/tarmactrr/Volvo/DSC01906.jpg" BORDER="0">
