Does anyone have access to documentation which tells which engine you have from the engine type number?

Specifically I have found the following stamped on the top of the block "EJ20BUG" and I would like confirmation of which engine this is - e.g. Jap WRX 95MY

many thanks in advance

 

See if you can read the sticker stuck to the bottom of the cam cover and also on the back of the block... easy to see with 'cooler removed !! The number is longer than the one you quoted....
