EJ20 - You're Going to Have to Be More Specific

EJ20 - You're Going to Have to Be More Specific

We get calls and emails all the time about people wanting to swap an EJ20 Subaru engine into their car and we love to help with this! However, it's not enough information since the term EJ20 is a very general identification for any Subaru EJ engine that has 2 liters of displacement. It's not specific to the model year, whether it came with a turbo, AVCS, etc. So when you are describing your engine to us for your build please be more specific (ex: version number or year). If you aren’t sure, then you are welcome to send us a picture and we can help identify it.

 

We've included a basic list of common engines with some general information to assist.

 

Not sure which engine you have? Watch this video to learn how to identify your engine.
