2002-2003 Forester 2.5 SOHC

Foresters - Will a 2003 2.5 SOHC direct swap into a 2002 2.5 SOHC.   It appears there may be electronic issues or not?  Other concerns?

 

Thanks!

should be a direct swap.. Use the cam pulley and crank gear off the original engine, and the intake manifold They might be different. Once that is done really any 1999-2004 SOHC cam engine will swap

I'm assuming a 2.5 DOHC would not work in a 2.5 SOHC vehicle or would it???

 

Thanks

No. It will not.

 

The USA/USDM Non-turbo DOHC 2.5 engines prior to '00  were the older Phase 1 version ('99 was transistion year and had Phase 2 blocks but used Phase 1 for everything else), and the electronics/sensors were not compatible. You 'could' technically use the short block, but I wouldn't recommend it unless it's new/rebuilt as used ones were probably overheated and/or the rod bearings  worn out.

 

And the newer ('11+) FB25 are also DOHC but not compatible either.

Thanks for the info on the motor.  Will the 2003 trans work as well in the 2002?
