To ascertain whether you have a JDM AVCS or non JDM engine, you need to get one of the plastic timing covers off from the front of the engine (3 pieces, left, center and right) like shown:

This is a picture of my 2005 WRX STi's EJ207 engine. It is an AUS DM vehicle which is almost identical or equivalent to the STi V-Limited JDM model. This has single AVCS on the intake cams only. The shiny camshaft gear, is AVCS, while the bottom black gears are non AVCS.

That aside your ebay listing is for a DUAL AVCS engine - this will not work with you as 04 WRX's did not come readily available with DUAL AVCS in any shape or form. If you decided to go ahead with it, you would be swapping over not just the engine, but ECU, locks and immobilizer.

Sorry to say but this is far from an easy plug in swap.
Hope this helps.
