Welcome. Check out the Subaru Retrofitting side of the forum for ideas

If you are referring to the ej25d, you can swap heads and use its bottom end with the heads original to the recipient car. What i am saying is in general. Do some reading in the retrofit forum for specific engine recpied. The ej25d would have a different intake manifold and/or wiring harness/maf/throttle body. Mechanically parts do interchange.

those engines codes are odd.....can you clarify.  like he said, you can bolt the 2000 heads to an earlier EJ25 block, but use thick headgaskets - like the 610 headgaskets for the EJ25D block.  i've done it before.

 

i'm not sure if it would work, i haven't calculated it out - but if you can use EJ25 Turbo headgaskets, those are much better as they don't fail like nonturbo EJ25 headagskets...but i don't think anyone has ever installed them on an EJ25D block before.

Welcome to the USMB. 
 

I'm going to move your thread to the retrofitting forum.

no, those engines are not a direct swap, either way.

 

but as mentioned you can use the short block of the ej25D and the heads & intake of the ej251 and make a good engine.

assuming the heads are good.
