Ej25 motor

Asked by Jul 21, 2017 at 09:00 PM

Question type: Car Customization

I have a 05 wrx ej205and the motor blew up. I also have a
short block for a 07 legacy ej25. I'm wondering if I can put
turbo internals inside the legacy block along with new
crank and my wrx heads on the legacy block. Could the
block hold that? Not sure if the legacy and sti blocks are
the same considering they are both 2.5

I am pretty sure the turbo engines had a beefier block with semi- enclosed decks rather than the open decks of the non-turbo engines. I would carefully compare the blocks and do research before using a standard EJ block.

Is it a legacy (outback wagon)?

Legacy limited

Just a sec checking Subaru tech site

Unfortunately you can not, if the legacy was a gt you would've been able to.

What's the reasoning behind that

They have the same block number on Subaru website
