Default Technical docs from Subaru?

Anyone know if there are technical documents available from Subaru like the ones all over the internet now for the Acura ITR? Would be interesting to see one for like an '04 STI and a '15+ or something.

There are plenty of deep dive tech articles for the DCCD, but I haven't any for the EJ257 or other parts of the car. Maybe I just missed them?

You can find the factory service manuals if you search for them online. You can also find technical service bulletins as well.

What I was trying to get at was the differences between the WRX/STI and Impreza similar to what the article I linked to is addressing with the Integra GS-R vs Type R. It's not super in depth, but still a technical overview of what changed and why for the STI.

I can deduce to some extent why compression ratios differ between the EJ255 and 257, or whatever other things. But it'd be nice to read Subaru's thoughts, I guess.

Sounds like I might need to become a subscriber for some of that information, which sounds a lot like a thing Subaru Technica International would do lol. Very private division from what I've heard.

Unlike with BMW or other companies where leaks are happening all the time and internal technical presentations are surfacing.

The Subaru Factory Service Manuals have tables that list difference between cross models.
