hey all.
i was curious to see if anyonee has ever tried making an ej22 intake manifold adapter so it will mount to ej25d heads, i lined up the manifold and it doesnt seem off by much. its mainly the bolt patterns. I have access to machinery. im gonna cad some designs out and post them. also if i can make it work, would anybody be interested in one?

i could also make one so the ej25 manifold(straight pattern) willl bolt to ej22(staggered bolt pattern) heads. one thing i gotta do is check to see if i can raise the manifold 1/2" with no clearance issues.

let me know what you think.

Is the pattern the same between the EJ25D and the EJ25 SOHC? I'd be interested in bolting the EJ22 intake manifold on the SOHC heads. Right now I'm running the EJ25 intake but the idle control valve is different.

the SOHC has the staggered bolt pattern opposed to the ej25d DOHC which has the straight bolt battern

ej25d (DOHC) pattern

ej25 (SOHC) pattern

so it would prob bolt up.
