Calling all JDM STI Engine owners

I'm trying to build up a database/table of the EJ207 engine codes for the new age Impreza. As most of you know, there are three model years in the 'new age' catagory.

MY01 - First production year, known as GxxA (i.e. GDAA, GDBA, GGAA, etc) Also called Version 7

MY02 - Second production year, known as GxxB (i.e. GDAB, GDBB, GGAB, etc) Also called Version 7

MY03 - Third production year, updated body sytle, twin scroll turbo on the sti. Known as GxxC (GDAB, etc). Also called Version 8.

What I am looking for!

I'm trying to map out the engine codes. The engine code can be found in two places. First is a small white sticker on the lower left passenger side of the black plastic timeing belt covers (front of the engine). The second stick is at the bottom back side of the drivers side head. You can see it from the top just a bit, and read it with a mirror (it is on the back side, just all the way down).

The Number on either sticker will look like:

EJ207DW3CR-xxx yyyyyy zzzzz

The yyyyyy is the block serial number, which is also stamped into the block on the right back top side, where it mates with the tranny. On the block it will usually be Byyyyyy.

So, could any/all of you with JDM STI or JDM WRX motors read this number and email/post back, also let me know if you know what MY it is. I'll keep the chart below updated with all of the info I can find! This will be VERY helpful for anyone who is considering doing an STI swap in the future.

Ok. Good news. I have just spoke with a real deal S202 owner in UK. Surely enough S202 has EJ207dw4ER. Just wanted to reconfirm since I got one of these bad boys.

I have every single News Pub book they have ever released for a Subaru. I have not seen anythign there.
