Please give me advise about intercooler!

I have RS2 Chip for 65mm pulley ... but don't know what cooler to use...
Important condition is that i don't want cooler outside my bumper i want it to stay hidden!
I think about from golf g60 stock cooler, or mk2 GTD i think they are same?!
Please give me advise....

My advise would be to not just look at VW parts, go to a scrapyard and have a look round at coolers on all sorts of diesel cars.

Ok, but how would i know wich kind of cooler is best for this set up!

just go off the size.  They all do the same job.
