yes they will. i am assuming you destroyed the bottom end of the EJ20 if you are now bolting them onto an EJ25.
Good Luck jeremy p.s.: use the head gaskets for an EJ25 Last edited by HndaTch627; 11-06-2002 at 12:54 PM. |

You know...people keep saying the WRX heads don't flow as well as the EJ25 heads, but I have yet to see proof.

well boys FWIW the WRX heads flow worse on the bottom then the EJ25 heads, but on the top they outflow them tremendously. I'd be worried about the cam's not having nearly enough lift to power an EJ25.

also I can understand flow being of importance but what about the fact that you have a bit more mechanical timing control witht eh WRX heads seeing as how they are DOHC. would it be worth it if you could find cams? Brad |

You could look into MY98 EJ25 DOHC cams... those might work with your WRX heads.

Just wondering, if it was the other way around (ej25 dohc heads on a ej20 dohc) would you run the ej20 head gasket?
