Difference between EJ202 and EJ20E


Recommended Posts

Hi!

 

I have a question: I'm thinking about buying a Subaru Forester MY98 or MY99 with a broken engine and replacing it. Now I found out that the Forester uses EJ202 engines instead of EJ20E used in Legacy and Impreza. What's the difference? Can I put in an EJ20E without changing the original ECU? There are many old and cheap EJ20 Legacy out there with working engines just rusting away so that would be a perfect swap...

 

Oh, to clarify: In Germany the Forester was offered with a 2.0 L engine (like Australia), not with 2.5 L like in USA.

 

Thanks!

The biggest difference as it would matter to this application is that the ej20e is phase 1 and the ej202 is phase 2. They are not electronically compatible, you will need to find another phase 2 ej202 to replace yours.

It was MY99 here in the US, I'm unsure if that was true worldwide as our model year guidelines are slightly different. What the Japanese and Australian market calls a 99 Legacy is what we call a 00. The phase 1 and phase 2 sohc engines are easy to distinguish from each other though. Phase 1 sohc motors have the head bolts and raised ridges on the valve covers, phase 2 sohc engines have larger smooth valve covers that hide the head bolts.
