Just hoping someone may have a lead on a thread that compares the 2 years and what was switched up? If in fact there is any real major differences besides being the Hawkeye style, any info appreciated

I actually took the time and went through the differences between the engines and transmissions over the years. That information is in these threads:

https://www.igotasti.com/vBforum/th...w-of-the-Changes-Over-the-Years-(2004-Present)

Also, this website is one of the sources I used, and they go through most, if not all, of the details changed from year to year:

Those links will serve you well.

Off the top of my head the big ones are :
the wheel bolt pattern (the 04 has the same 5x100 as the wrx, usually STI is different at 5x114.3),
obviously the whole exterior styling package (hawkeye vs blobeye, tail lights, hood scoop size, interior controls, etc...)
Some minor chassis stiffening
I think the 04 and the 06 may have different internals for the rear diff. This is mostly inconsequential except for what fluid you put in them
Minor engine-bay reorganization?
