Hey guys, so i have the EJ22T and was thinking of swapping to an EJ25 the NA SOHC same as the foresters and things like that, i was wondering has anyone done this? I assume so, i searched but did not see anything. The reason i want to swap is because during the RallyX's i've done i need TQ and the 22 just doesn't have it.

Search for frankenmotor swaps. You can use the EJ25 short block, but the newer heads are not compatible with our older sensors. People have gotten butt loads of low-end torque (by NA standards) with the 2.5 block on 2.2 heads.
A full 2.5 long block would give you
less low end than you have now

Good to know, ill look up the "Frankenmotor" but essentially its using the EJ25 block with EJ22 heads? i would assume delta cams, and thats more or less about it. I guess its true subarus are giant LEGO's and everything just snaps together.
