Emailed raceeng to buy some stuff from them but i have a question and so do they, here´s their email:

Nobody here, or at Darton knows if the M.I.D. kit will fit that D16A9 Jap
spec motor.. They work on all the U.S. spec D16 motors, but the Jap stuff
tends to change a lot. I really don't know if they are the same or not..

Does anybody have the answer for it?

P.S: Our d16a9 is your dohc zc

 

bump...no one?

 

Last try... no one builted a dohc zc ever?

 

you might post this in the ef forum. lots of guys running zc's over there.
