Doing a ej205 while possible is a major pain in the ass. Item id 5814 models usdm wrx 2006 07 usdm wrx 2008 2014 usdm sti 2004 2007 usdm fxt 2006 2013 usdm outleg 2005 2009.
Jdm Ej205 Wrx 2002 2005 2 0l Long Block Dohc Engine Swap Package
Jdm ej205 vs usdm ej205. Jdm 20l ej205 replacement engine for usdm ej255 wrx. Customers who plan to swap their vehicle use either the ej205 from the usdm 02 05 wrx the ej207 from the jdm version 7 and 8 sti the ej255 from the usdm 06 07 wrx and 04 08 forester xt or the ej257 from the usdm 04 07 sti. Im wanting to potentially swap my 98 25rs with a jdm ej205 with avcs and i was wondering if theres a difference between the jdm and usdm harnesses beside the usdm not having avcs plugs. Im wondering because i dont mind merging my harness with the jdm one myself but i can only find the post. You have to do cam triggers cam gears whole intake manifold ecu and more to get them to pass. If you are doinghave done an engine swap with an usdm 2002 2005 wrx into another chassis like a 25rs the same rules apply.
Any vehicle that is wired for a usdm ej205 can use the 2001 2005 jdm ej205 and ej207 longblock but will require the addition of avcs wiring and an avcs compatible ecu. The 207 bypasses that since it has tgvs and the same harness plug as the 205 usdm ecu. These engines are newer more reliable and more powerful than older jdm engines. Thats where all the wrong information of jdm will never pass smog comes in.
