Specifically EJ22T EJ20T EJ25 (both versions) and EJ257.

Im looking as well, but I thought you guys could help get the info faster. If you find conflicting info please post it too, so we can work it all out.

Here is some of the info, Id assume its all correct? http://www.wrxworld.com/iclub/engineconfig.jpg
It looks like everything we would ever need, and helps me to get 2.33L displacement like I wanted to start with! (which screws all my flow calculations and turbo choices :roll: )
