Would like to know if the fuel rails on the Version 8 JDM intake manifold are the same as the USDM STi?So I could know if aftermarket rails would fit. And I know there is a web site that sells them but I can not find the thread that had a link to it anymore. Anyone have some answers?

no
usdm wrx rails should work though

usdm sti -sidefeed
usdm wrx -topfeed
jdm sti/wrx -topfeed
