Default Difference between v4 and v3 sti? Quickest way to check engine type/number?

Slow day at work so i googled my vin number. Turns out that my car is a V3 STI, not a V4. However i did have an engine swap a few years ago (when i knew nothing about scoobs). How do i go about finding out what type this is, EJ20 or EJ207 (is the 207 much different to the 20?).

Also does this mean there are any inherent differences i have been thinking its a v4 all along!

V3 to V4 is quite clear because they had different dashboards. Mechanically there is hardly any difference.

Ash,

Two pages to look at.

http://www.type-ra.com/impreza-timeline/

But the main difference is the dash. The RA's as an example.

Thanks for that! wealth of info on these pages . but how can I physically check what new engine was put in? are there locations of ident numbers etc where i can check? I don't really fancy ringing the garage saying - hi you know that engine you put in for me 2 years ago, was it from a v4 or a v3 etc

Ash,

Scroll through this informative thread from Type RA (again) and it should help.
