your an idiot. and not every swap require major work.
and to the OP. if i get this right i know alot of 2g gst's are starting to put the 3g eclipse blocks in their car and still run the 4g63 head. so i would imagine that you could maybe try to find a 4g63 head. and piece together a turbo setup and drop the head on your block and run boost. i hear the combo is a good turn out.
