im trying to find out if an exhaust manifold will be interchangable between a b18 head and f20c head. the reason why im asking is i have a custom build turbo manifold for a b18 that would be nice to use for my new build. and im currently in japan so i cant just go look up exhaust gaskets lol
thanks everyone

 

Why don't you just buy stuff there that isn't available in the US and bring it over... heck just buy a new engine

 

No. They are totally different in port layout and design.
