Hi there,

I am currently rebuilding a jdm ej253 engine with new gaskets to put into my impreza. I was wondering if there was a difference between the jdm gaskets and the usdm gaskets used in these engines? If not, does anyone have a lead on where I can find gaskets for a jdm ej253?

Thanks, Billy

In old Gen and H6 JDM I’ve never had issues buying US gaskets. Ive only seen the generic pvc type hoses be different.

    Should be largely the same.

     

    Use STi Head gaskets, just like the USDM 2.5s.
