As said, all 2.0 litre engines are EJ20 (the '20' for 2.0 litre)... then the rest of the code letters/numbers is code for MY, variant, etc, etc....
Check the driver's side black cam cover - it might still have the white sticky label intact. If you have the original cam cover, the label should have the correct full engine code printed on it, "EJ205.. blah...blah...".
I think the VIN plate on the passenger front turret has the full engine code too...
