xyzb Posted August 8, 2016 Share Posted August 8, 2016 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! Link to comment Share on other sites More sharing options...
matt167 Posted August 8, 2016 Share Posted August 8, 2016 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 Link to comment Share on other sites More sharing options...
xyzb Posted August 8, 2016 Author Share Posted August 8, 2016 I'm assuming a 2.5 DOHC would not work in a 2.5 SOHC vehicle or would it??? Thanks Link to comment Share on other sites More sharing options...
wtdash Posted August 8, 2016 Share Posted August 8, 2016 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. GL. Td Link to comment Share on other sites More sharing options...
