Engine conversion


 

I’m planning on doing another engine conversion on my ‘91 MT Vanagon. Currently I have a ?EJ 25 DOHC from a 1998 Forester. I could have a low mileage 2004 Imprezza engine. My question is, can I use my current Kennedy adapter plate and all the other components? They are both EJ 25 engines, except the new one is a SOHC. I also have the complete wiring harness from the Imprezza.?
Thanks for your help.?

I’m running a KEP adapter plate, flywheel, pressure plate, carrier bar, and clutch on my 2006 Impreza SOHC EJ253. I initially used it on an EJ22. I’ve heard the EJ engines in Vanagons described as legos, and I feel it’s an accurate metaphor.?

Point being, it should work no problem. But maybe give KEP a call to confirm.?

I also am running the KEP adapter and when I ordered it they said the adapter would fit the EJ22 and EJ25 with no issues. Mine is a EJ25 from a 05 Impreza and had zero problems with the adapter fitment whatsoever. The engine cradle is another issue altogether.?

Morning Christoph. ?I put together a few notes related to upgrading your engine from a 98 DOHC ej25 to a 04 SOHC ej25.

Kennedy Adapter plate
Direct swap.
Engine Mount
Should be able to directly swap. ?I’d suggest new mount/pads while you’re in there.
Wiring Harness
You’ll need to remove your old harness. ?Reconvert/install new 04 harness and all related electricals.
Intake ducting
Direct swap
Coolant Plumbing
Direct swap
Oil Pan
Direct swap

To be sure you should talk to Kennedy. ?But I am 99% sure its the same.?
