I believe the 2.5 out of the LGT will work. The stock legacy is N/A so it won't work out too good with a compression ratio of like 11:1 and like 14 psi of boost thats a grenade and a half.

As far as I am aware the motor in the LGT is the same as the EJ257 in the STi other than the internals. Mainly the pistons, rods, crank, and cams. That is speaking for the new Legacy GT turbo models, not the older N/A LGT. I believe the older one has several differences in block design and a lot of ecu differences. Someone who is more knowledgeable can come in here and correct me if I'm wrong.

Oops didn't notice you said change the internals.

you think that would be better than a wrx shortblock and put my headers and stuff on?

I wouldn't be comfortable giving that advice as I am not that knowledgeable on legacys. I would recommend getting an Sti ej257 block and put in some cp pistons and rods of your choice.

That's actually pretty good advice. You can find STi engines for pretty decent prices on here.
