Default please help with ej257 swap in forester XT

First question is about the EGR system. my old motor (ej255) has an egr system but im not sure if the ej257 does...my friend is doing the swap and is a bit confused about how/if to swap over the EGR system to the new motor.

i have some more questions but this one is most important right now. thanks in advance.

There should be an EGR system on there, all 1995 and newer Subies have EGR systems. Look around for the valve, they all look the same it shouldn't be hard to find.

Your old motor; '06 FXT is the same as the '06 WRX motor, and comes with that air pump stuff. Just have it unplugged and have the code turned off.

The EJ257 motor is going to run a lesser compression ratio. 8.2:1 vs your 8.4:1.

thanks...i will do that. however the compression ratio will actually be a bit higher (8.5:1) as this is a rebuilt block and that is the new comp ratio with the CP pistons.
