I just updated my electronic parts catalogs with new cd's. And guess what car is in there? Anyone? Yep, MY04 STi. If you have any specific questions, maybe I can find out. There isn't any specifications listed as to what size parts are, but you can tell alot about how things are put together from th parts explosion diagrams. For instance, the trans has an oil pan, an oil pickup and an oil pump inside. I thought that was cool. Another little tidbit, the water spray for the intercooler is a purpose built tank in the trunk. I couldn't find the switch to control it or the DCCD, doesn't mean that they are there, just means I can't find them yet. But it's only a sneak peak, there's not to many things available and most don't have prices yet.
