My mom and dad bought it at a grage sale and the guy just said it came out of a late 80's honda. any idea? only numbers i can find on it are "PM24". Obviously it's and intake mani but what motor and how much is it worth?

 

That's a dual carb setup for a JDM engine. Civics originally sold in the USA never used this system. Someone imported an engine from Japan and swapped the manifold to one with fuel injection, like everyone does. I'd say it's value is only as scrap metal.

 

alright thanks.
